Sensor ventilator for COVID-19

The COVID-19 virus is spread by direct contact with an infected person's respiratory droplets (generated through coughing and sneezing). Individuals can still become infected by coming into contact with virus-infested surfaces and touching their faces (e.g. eyes, nose, and mouth). The people infected with COVID-19 suffered from breathing issues, lung issues, etc. In the pandemic, hospitals have been facing shortages of ventilators. Many organizations have already designed low-cost emergency ventilators, but they have not included a sensor or alarm system. To overcome this problem, new ventilators have come on the market that have sensors or alarms. These sensors track breathing and detect malfunctions if any. During the COVID-19 crisis, a new open-source sensor and alert system made emergency ventilators more helpful. It uses low-cost, widely available parts so that they can be produced quickly and inexpensively to help address shortages.

The ventilator monitoring system uses a similar tracking algorithm to the pressure signal measured in the patient's airway. When the highest and lowest levels of the pressure signal are far apart, the ventilator is working correctly. If those levels get too close together, there might be a malfunction, such as a loose tube. It attaches to a pressure-cycled ventilator and monitors the breathing cycle. The device, which is smaller than a deck of playing cards, includes a pressure sensor, a microcontroller, a buzzer, three buttons, and a display. It shows metrics including respiratory rate and the pressure levels in the airway during inhalation and exhalation. Clinicians use these metrics to monitor patients and adjust ventilator settings. It sounds an alarm when the pressure is too high or too low when the breathing is too fast or too slow, or too much time has passed since the last breath.

Data Science

 

Recently, we have seen or used more technologies in our daily lives. With the rapid growth of technologies, one new technology has been added, i. e., data science. Let’s get a detailed knowledge of data science. Data science is the interdisciplinary study of noisy, structured and unstructured data. It employs scientific methods such as processes, algorithms and systems to extract useful information and conclusions from the information. This knowledge and actionable insights can then be applied across a wide range of fields. Data mining, machine learning, and big data are all connected to data science technologies.

Data science technology is used to help effective data scientists discover relevant questions, acquire data from a variety of data sources, organise the information, convert the results into solutions, and present their findings in a way that favourably influences business choices. Because these abilities are required in nearly every industry, talented data scientists are becoming increasingly important to businesses.

The benefits of a data science platform

By allowing teams to exchange code, findings, and reports, a data science platform eliminates redundancy and fosters creativity. By simplifying management and implementing best practices, it eliminates bottlenecks in the flow of work.

In general, the best data science platforms aim to:

• Make data scientists more productive by helping them accelerate and deliver models faster and with fewer errors.

• Make it easier for data scientists to work with large volumes and varieties of data.

• Deliver trusted, enterprise-grade artificial intelligence that’s bias-free, auditable, and reproducible

 

Data science used in real life:

Smart energy meter using Raspberry pi

 Many real-time problems can be solved with the Internet of Things (IoT)-based apps, which are becoming increasingly popular nowadays. Due to customer power theft, traditional billing systems suffer enormous financial and power losses. As a result of this, consumers had no idea how much electricity they were using in real-time. The biggest drawback of the traditional system is that if one of the electronic energy metres breaks down, the electricity department will not be notified until the liability of the person who was supposed to collect metre readings has expired. Repairing or replacing a damaged metre can take two or more months. When you have a standard billing system, an electricity board representative comes to your house and takes an image. The electricity board then pays the representative a fee for each visit, making the process extremely expensive. In addition, the energy board will suffer a significant financial loss due to the current structure.

Hence, a new IoT-based electric metre monitoring system based on an Android app has been proposed in this article in order to reduce the amount of human labour required to measure the amount of power used and to raise awareness among users about their own excessive use. The electric meter's pulse can be retrieved with the help of a microcontroller and an optical sensor. To cut down on human error and the expense of energy usage, a low-cost wireless sensor network for digital energy metres and a mobile application that can automatically interpret the meter's readings have been built using a Web API. The idea of a smart energy metre based on Raspberry Pi is introduced in this blog. We use the Raspberry Pi because it is energy-efficient, consumes less energy, is faster, and has two UARTs. A minor adjustment is done, but there is no replacement for the metres that are currently installed in our homes. Instead, the metres that are currently installed are transformed into smart metres. We can easily access the metre and see the reading by going through a site page that we have developed. On the web page, you can view the current perusing with an expense. The instrument can be automatically activated and deactivated.

If implemented properly, the proposed method will allow the user to see their electricity consumption in a simple and understandable manner. This enables them to calculate the cost of their daily power consumption, allowing them to cut their usage. Because it is an Android application, users may keep track of their consumption from anywhere. Android devices are the norm; Android devices are used by the vast majority of people. The Raspberry Pi is a low-cost, high-performance computer that connects the database and the measuring module.

The entire system can be broken down into three parts. This includes energy metres that use microcontrollers to measure power use in real-time. The metre reading can then be sent to a server via a WLAN Module-based network in the second phase. An upgraded data management system based on user-friendly software is included in the third phase. This system has two different access points, with distinct passwords for consumers and electrical authorities.

This project investigates the development of an electrical billing system based on a microcontroller. This project's goal is to create a computerized utility bill.

IOT based top 5 project ideas

 The top 5 project topics will be productive for your career path.

Everyday technology has been sky-point. Technology has become a dominant part of our life. We can’t even imagine our life without technology. In the last 2-3 years, the COVID-19 pandemic has proved the importance of technology, its ease of staying connected to people, surviving and working. For researchers, the pandemic has become an opportunity to research the technologies that will help us to get food, work and so on. While studying this research, I have come across some technologies that have tremendous use in our daily lives. In this blog, I will be talking about technologies that will never go out of scope. If you are looking for trending project topics, you have come to the right place. So, let’s get started.

          1.      Health monitoring application:

   

The current situation of human life and living environments requires constant monitoring of human health. For the future of healthcare, the Internet of Things-based smart health monitoring system is vitally important. Advanced communication and information technologies have enabled the Internet of Things (IoT) for a wide range of practical applications. There are several physical devices in the Internet of Things that gather, transmit, and deliver data in various interoperability ways.

There are three primary functions of IoT: storing data for display and communicating it. It's designed for continuous remote patient monitoring, with data clustered and assessed. A significant improvement in health management for rural and urban patients is possible with this technology. If you're looking for a good opinion on technology diagnosis, this may be useful for you.

        2.      Shopping delivery drone/ robot:

     COVID 19 makes us realize how dependent on labour we are. In a labour-intensive area like business, hotels, malls, hospitals and so on. In this pandemic, robots have taken over labour. Robots are being used to disinfect the area and even deliver food to the people.

  

      A reliable logistics system is required to support online commerce. Practically speaking, goods delivery is not virus-free. Contactless deliveries are offered by several delivery companies and restaurants in China and the United States, where items are picked up and dropped off at a pre-determined location instead of from or into a person's hands. To protect the sanitary condition of delivered items, delivery organisations must create explicit rules before robot delivery services become commonplace, though.

         3.      Distance learning (e-learning apps)

     Approximately 1.57 billion kids were affected by school and university closures in 191 countries as of mid-April. Because of quarantine restrictions, many educational institutions began to offer courses online to ensure that education was not delayed. The technology used in distance learning is similar to remote labour, including AR i.e. Augmented Reality, VR i.e. Virtual Reality, 3-D printing, and artificial intelligence-enabled robot teachers.

    

A student or teacher's physical presence is different in distance education than in traditional education. This is a rather broad statement, however. Overall, it means more freedom for both learners and instructors. However, completing a course of study successfully demands more discipline and organisation than ever before.

A student's ability to choose courses that meet their schedules and resources exemplifies the increased freedom of remote learning. (Teachers can follow suit.) The students can also pick their preferred teaching style and location when it comes to digital learning.

       4.      Robot nurse

         

 Robots are being employed to check patient health in some of the hospital's departments. Doctors work in emergency rooms in hospitals. Doctors find it extremely difficult, if not impossible, to be present at every patient's preferred location and time. In this case, an IoT virtual doctor will come in handy. The robot allows a doctor to virtually roam about and communicate with individuals in a remote place at will. Using this robot, doctors will be able to virtually travel to any location at any time and receive medical reports through a video call.

According to some survey reports, many manufacturing company jobs will be replaced by robots, and thereafter, new jobs to monitor the systems will be created in the process. Professional training and social welfare policies must be in place to prepare workers for the change.

         5.      Human Safe Sanitization Tunnel Using Silver ION Technology

         

 Sanitisers have become a need in our modern world. Water was utilised to clean our hands with alcohol-based sanitisers, soap and handwashes. Many studies have been conducted to protect us against viruses. Silver ion technology, for example, is superior and helps conserve water.

The system is designed with a silver ion-based compact disinfection tunnel to address and find issues while remaining safe and 100% functional. To save money and space at the entrances, the tunnel has been made extremely compact. It is also designed to fumigate rather than spray, which requires far fewer chemicals and thus saves money.

The following are the benefits of this tunnel:

v  The designed tunnel is compact and hence needs less space.

v  This system is well-proven technology that kills bacteria and viruses.

v  System is set to auto-start and stop mode, on human sense inside the tunnel.

v  Silver ion technology is cost-effective.

In the upcoming blogs, we will study each topic in depth.

Embedded Smart Motorcycle Helmet

 A motorcycle rider's helmet is one of the most crucial and basic safety gadgets. Driving requires regular monitoring of your GPS navigation system as well as your speedometer, as well as any other relevant rider-related information. It is not at all safe to be distracted by external noises or phone notifications. A number of motorcycle helmet manufacturers have now developed futuristic smart helmets for the motorcycle accessories industry.

A rear-view camera, a touch panel, and other smart features are included in these smart AR-enabled motorcycle helmets with Bluetooth. The safety of the rider is the top priority with these smart AR-enabled motorcycle helmets with Bluetooth. In this blog, we'll look at what the smart helmet actually does.

As a solution to the problem of user distraction during rides, the smart helmet provides 360-degree visibility, noise suppression, and smartphone connectivity in a simple and easy-to-use package. Because it includes a wide-angle rear-view camera built-in, the Heads-up display (HUD) can project photos and videos onto the HUD to reduce potential blind spots.

You feel like you're more technologically advanced than the super-efficient rear-view mirror when driving with a smart helmet since it allows you to keep an eye on what is occurring behind and around your vehicle without having to turn your neck. Also, you can boost or decrease the volume of ambient noise using the easy cross sound equalizer, which comes in handy when you are in a noisy location. Wearing this helmet provides you with the ability to connect not only with Siri as well as Okay Google but also with the helmet within range using your smartphone Bluetooth. To charge the helmet charging port is provided. This helmet can also through solar plate placed on the top.

Numerous studies are being undertaken around the world to stop the spread of the CORONA Virus after we all suffered from the pandemic COVID-19. We created a helmet with all of the aforementioned qualities, as well as our own unique concept.

The smart helmet is equipped with sensors that detect your body temperature. Your bike will only start if your body temperature is normal, otherwise, it won't. As a result, it offers protection and control over the spread of COVID-19.

Which Technology Is Better ?????

React Native vs Flutter vs Ionic vs NativeScript vs PWA

How does React Native compare to Flutter, NativeScript or Ionic? What are the differences? Which 

 one should you learn? How’s performance for each of these options? I chose 8 metrics to compare 

these technologies and help you with that decision.

What are Flutter, React Native, NativeScript and Ionic?

 This article will compare Flutter, React Native, NativeScript and Ionic.

All four technologies allow you to build real native mobile apps for both iOS and Android - without the need to learn Swift, ObjectiveC, Java or Kotlin!
Instead, you’ll use JavaScript (for React Native, NativeScript and Ionic) and Dart (for Flutter). Hence you’re able to create native apps for both platforms with one language instead of two - this obviously reduces the learning effort you have to take to build your mobile app by a lot!
Great! So how do these technologies differ, which one is the best choice for your next mobile project? Let’s take a look…

Flutter

 

Flutter is both a SDK (software development kit) and a framework for Dart - a programming language developed by Google. Flutter itself is also developed by a Google team.
The idea behind Flutter is that you write Dart code which can be compiled to native code that runs on the target device. You use Dart + the Flutter framework to build user interfaces composed of so-called widgets. Flutter ships with a bunch of pre-configured widgets (buttons, tabs etc) and you typically use these to then also build your own, more complex widgets.

Besides writing Dart/ Flutter code, you’ll also use the SDK portion of the technology. That basically is a set of functionalities that help you during development (IDE extensions, development server, live-updating of your app on an emulator or real device) and with deployment (compile your app code to native code).

React Native

 

React Native is a technology/ framework developed by Facebook.
It uses JavaScript and the React library to allow you to build beautiful user interfaces composed of React components.
Important: Unlike in “normal” React apps built for the browser, you’ll NOT use HTML tags. Instead, you’ll use a set of pre-built components which will be compiled to native code by the React Native tool chain.
You’re still able to use packages like Redux and knowing JavaScript and React of course allows you to quickly get started with React Native, too.

NativeScript

 

NativeScript also uses JavaScript to build native mobile apps. It comes in different flavors - pure JavaScript/ TypeScript, with Angular and with Vue.js.
It gives you the option of working with different frameworks as you can see - the different options are developed independently from each other though. So you might have an easier time or more built-in components with option A than you have with B. All options are under active development though, hence it’s best to simply dive into the docs.
Like Flutter and React Native, NativeScript also ships you a bunch of pre-built components which you use to compose user interfaces. It does not work with HTML but with its own components (like React Native).

Ionic

 

Ionic follows a different approach than the first three options!
With Ionic, you still create a real native app but you do this by creating a web app (with HTML, JS and CSS) which will be wrapped by a real native app that hosts a webview (basically a hidden browser).
Since you build a web page in the end, Ionic is pretty easy to get started with for web developers.
Starting with Ionic 4, Ionic is basically a huge suite of components you can use (buttons, cards etc) with any front end framework (or none at all).
Ionic also provides a lot of tooling that makes the development of mobile apps easier (e.g. a development server for running your app on an emulator/ real device with live-updating) and it also bundles the app into shippable packages. Additionally, the Ionic team is involved in the Capacitor project which offers a lot of JavaScript packages you can add to any (!) web project to tap into native device features like the camera.

How should we compare these options?

After these brief introductions - how should these options be compared?
Let’s also add the native platform languages (Java/ Kotlin for Android, Swift/ Objective C for iOS) to the mix and have a look at eight totally subjective metrics.

“Write once, use everywhere”

What does it mean?

With this metric, I want to explore how much of the code you write can be re-used for both platforms.
Don’t get me wrong - the whole idea behind all these technologies is to re-use code and only use one language but you might still need to write different code (despite using the same language) for the different platforms.
This could be required to position elements differently or because you need to use different UI components as not all UI elements exist on both platforms.

 How do all options compare?

We see mixed results.

• Ionic: Awesome re-usability! The “wrapped web app” concept ensures that you can easily re-use your code - you’re just building a wrapped web app in the end. The great component library of adaptive components (i.e. automatically styled for the platform the app runs on) also helps.
• Flutter: Also really great to re-use. The widgets it ships with often don’t adapt to the underlying platform, instead you use Material Design on both platforms by default. The Flutter team is providing more and more iOS-styled components though. You can find out on which platform you’re running and manually swap widgets but that’s of course a bit more work than required by Ionic. If you need platform-specific re-styling, you can move the position of Flutter on the slider further to the right.
• NativeScript: Pretty similar to Flutter, but it does not apply a style system by default though. Many components automatically compile to their native equivalents and therefore need no re-styling (unless you want to). Components that do not exist on both platforms have to be managed by you (i.e. you have to decide which component to render on which platform). Overall, code can be re-used quite well though.
• React Native: Also compiles to native defaults but only provides a basic set of components to start with. You have to style most of them on your own, hence more work is required to achieve appropriate styles on both platforms. Generally, code can be re-used though (since you still only use one language and libraries like Redux need no adjustment).
• Native Languages: Obviously you can’t use Java with Android for iOS development (or the other way around). Therefore, code re-usability across platforms does not exist here.

“Learn once, write everywhere”

What does it mean?

This metric sounds similar to the previous one but it actually means something totally different. Even if you have to adjust some code to the underlying platform, the question is: How complex is that adjustment? Do you have to learn different language features for the different platforms?

How do all options compare?

On this metric, we got basically two extremes in my opinion. All options except for using the native languages require only one language to be learned. That is true for both solutions like Ionic - which follows a “use one code base for both platforms” approach - and alternatives like React Native, where some differentiation may be needed.

Rich pre-styled Component Library

How easy is it to build beautiful UIs? Do you have to create and style a lot of components (UI elements) on your own or do you have a rich suite of pre-built ones? Are the components adapting to the underlying platform automatically? That’s what this metric is about.

 How do all options compare?

On this metric, the options differ a lot!

• Ionic: Ionic in its core is a big set of pre-built (and pre-styled) components. The compiler/ toolchain which yields a native app is also part of the Ionic package (handled via its CLI) but it utilizes other packages like Cordova or Capacitor. The components provided by Ionic automatically adapt to the platform the app runs on and therefore, Ionic makes the creation of beautiful, native-looking apps a breeze!
• Flutter: Flutter also ships with a comprehensive suite of built-in widgets. These mostly use the Material Design, some Cupertino-style (iOS style) widgets exist, too. More and more iOS-styled components are getting added. With all these widgets, you can quickly create nice-looking UIs without doing too much manual styling. Only if you need different looks for different platforms, some effort can be required since the widgets don’t adapt automatically.
• NativeScript: NativeScript ships with a decent set of UI elements which comprises the core set of elements you typically use. Not every niche component is included but the components it does ship with adapt to the underlying platform. Still, some manual styling is most likely required, additional widgets might need to be created by you. It’s certainly less comprehensive than Ionic or Flutter.
• React Native: A decent set of built-in components is provided but a lot of them need to be styled by you. And they’re non-adaptive, instead - just as with Flutter - you get alternatives for both operating systems. That requires adjustments in your code, where you have to choose, use and style widgets conditionally.
• Native Languages: As you’d expect, both languages/ frameworks ship with a rich suite of native UI elements which you can use to build your user interfaces. Obviously, they’re non-adaptive since you build your UI for only one platform at a time. But the components provide the default platform styles and can of course also be customized. 

Ecosystem / Third-Party Libraries

What does the ecosystem look like? Is it easy to find help (on Stackoverflow etc) and are there enough third-party libraries available to add that one feature your app needs?

How do all options compare?

• Ionic: Ionic uses JavaScript for its logic - and whilst you can use it with any (or no) JavaScript framework, it provides especially great support for Angular. Therefore, you benefit from these ecosystems. And the JavaScript as well as the Angular ecosystem is huge! Thousands of threads on Stackoverflow and packages on npm help you solve your problems. 

•  Flutter: Flutter is seeing tremendous growth! You find quite a lot of discussions on Stack overflow and third-party libraries and packages (on its own platform). Despite being relatively new, it’s already quite mature and has a decent ecosystem.

• NativeScript: NativeScript lags behind a bit. It’s actually a great SDK/ framework but somehow, it didn’t fully take off thus far. But it looks like it’s gaining some traction at least and you do find more Stackoverflow threads and third-party packages. Additionally, new initiatives like Nativescript-Vue show that the community is very active and also allows you to use a framework other than React and Angular to build your native mobile app.  

• React Native: It’s THE most popular solution for building native mobile apps with JavaScript. At least when we look at the alternatives that really compile your app to native code. It uses JavaScript and React, hence you got those ecosystems available. Additionally, React Native on its own has quite a vibrant ecosystem and community, hence you find many threads on Stack overflow and a lot of third-party packages that add missing functionalities. A downside is that you often need to rely on the ecosystem, since only core features are included in React Native itself.

• Native Languages: These languages are extremely popular and therefore Stackoverflow is exploding with threads on them. You find plenty of libraries you may use and you therefore probably won’t find an issue that can’t be solved.

Popularity & Coverage

Having a vibrant ecosystem is a good thing - but how popular is an option? This is not necessarily the same, as you could have a rich ecosystem due to the alternative being mandatory in an industry without it being very popular among developers.

How do all options compare?

• Ionic: Ionic is pretty popular. It empowers (web) developers to build native mobile apps in the fastest possible way. If we take Github stars as an indicator, we can see that it has around 39k stars at the moment I’m writing this (14th August 2019). 
• Flutter: Flutter had a strong year on Github (72.6k stars, up from 30k stars a year ago) and is still extremely trending. It’s heavily advertised by Google and they clearly want to make it a big thing. And it’s fairly well-received. Working with it is really fun!
• NativeScript: As mentioned before, NativeScript is not the most popular option. It has 17k stars on Github (14k a year ago) and you can “feel” that it’s less popular. But this might be changing. Lately, a lot more positive comments and discussions spun up and initiatives like NativeScript-Vue definitely bring more live into the ecosystem.
• React Native: React Native is the king. 80k stars on Github (65k a year ago) speak a clear language. It actually has its flaws and if you dive into discussions, you can see that not all developers are loving it. Not everything works flawlessly but overall, it uses an extremely popular library (React) and the most important web development language (JavaScript) and gives you real native apps. These are indeed very strong arguments and the reasons for its popularity.
• Native Languages: You don’t find Android and iOS on Github, so I can’t provide any stars. But these two options ARE very popular. Have a look at the books, courses, articles, threads and media coverage that exists on these technologies. If someone wants to build an app, he’s most likely looking into the native languages first.

Performance

This metric probably speaks for itself - how do the different technologies compare from a run-time performance perspective?

How do all options compare?

• Ionic: Ionic offers the worst performance as its a wrapped web app in the end. But this is often misunderstood! “Worse” sounds extremely bad but “worse” doesn’t actually mean “bad” or even “horrible”. Instead, you got worse performance than with the other approaches but on the devices we got these days, your app will probably run more than smooth! If you only (imaginary!) got 100fps instead of 105fps - would you notice a difference? You wouldn’t, so keep Ionic in your mind for your next app!
• Flutter, NativeScript and React Native: These three all offer you real native apps (compiled from your code) and therefore, they provide a better performance than Ionic does. Doing exact measurements on who of the three is best is pretty hard or even impossible as it depends too much on the app you’re building, the device you’re using, the operating system and the version of Flutter/ NativeScript/ React Native used. They all provide really good performance, that is what you need to know!
• Native Languages: Well, you probably can’t beat the native languages. Well-written native code should always be more performant than compiled native code.

Accessing Native Device Features

Your mobile apps most likely need access to some native device feature like the camera or GPS. How easy is it to get that access? And how easy is it for relatively new features (e.g. AR APIs provided by Android/ iOS)?

How do all options compare?

•  Ionic: Ionic uses Cordova or its own solution, Capacitor, to give you access to native device features. It provides a very decent set of packages to access common native device functionalities like the camera. You can also write your own wrappers around native functionalities and then include them in your code of course.
• Flutter: Over the last year, the Flutter team put a lot of effort into providing official packages for some of the most common native device features you need access to. There also is a very vibrant ecosystem and hence you find a package for pretty much any native feature you might want to access. You can also write and connect real native code if you need to.

• NativeScript: NativeScript offers a very decent set of plugins (developed both by the NativeScript team as well as other developers) that give you access to the important (and even some less-common) native device features. Additionally, it’s also easy to connect your own native code to your NativeScript app.

• React Native: Being the most popular solution, you find a rich set of third-party packages as well as some built-in APIs for accessing native platform functionalities. Relying on third-party packages (which you mostly have to do) of course has the disadvantage that the core maintainers of that package might quit, hence the support is not on the same level as it is with Ionic or NativeScript.

•  Native Languages: Needless to say, that you got ALL APIs for a given platform available here. You are directly accessing the native APIs after all.

Real-World Usage

It’s great if you’re convinced about a technology - but how does the rest of the world think about it? This might not matter to you but if it does - here’s a quick comparison.

How do all options compare?

• Ionic: Ionic still has no ground-breaking killer app but it has a nice showcase of apps that are using it. Some bigger companies are using it and the speed of development you can achieve with Ionic is probably especially appealing to highly agile and/ or small teams. Not meaning that no bigger companies are using it (as you can see in the showcase).

•  Flutter: Despite being relatively new, Flutter already has some exciting apps being built with it - Google’s AdWords app for example. You can find a full list in their showcase, chances are that we’ll see more great apps on that page soon.
• NativeScript: You find some big names in its showcase, mostly companies from the B2B tech space. And a lot of apps seem to be internal apps (or apps for the clients of these companies). If we consider B2C, there seems to be no killer app available - that is probably related to the lower popularity of NativeScript.

•  React Native: React Native is used by a couple of bigger companies, Facebook itself (which develops React Native) for example. But we also have to note that one big company which used it - AirBnB - lately moved away from it. Probably also because of that article, the RN team is working on getting rid of some of the mentioned limitations and problems.

•  Native Languages: The vast majority of apps available is written in these native languages. You find thousands of big apps and games that use these languages.

So, what should you choose?

With all these metrics discussed - which one should you choose?

There is no bad choice here, these are all great alternatives!

First of all, you have to decide whether you want to stick to the native languages (Swift, ObjectiveC, Java) and accept the disadvantage of learning two things and writing two apps. This is a lot of work and mastering two languages and platforms is way harder than mastering one. But you saw a couple of “pro” arguments, too.

If you don’t want to use the native languages, you have to decide whether you want a wrapped-app solution as Ionic offers it. Whilst having the performance disadvantage (which might not matter that much as discussed above), you will get a super-fast development experience. You can use your web development know-how and build two apps with one tech stack in little time.

But if performance is super-important to you - or you need to access a lot of (advanced) native device features - you might want to take a look at React Native, Flutter or NativeScript. Here, the details outlined above matter as these approaches are pretty similar otherwise.

Or use a Progressive Web App!

The alternate Solution is .. 

A PWA is a web app, not a mobile app. This is really important to understand - you won’t distribute it via the app stores!

But it looks and behaves like a native app, you also have access to a decent amount of native device features in modern browsers.

This makes them a good alternative for many but not all use-cases. If you absolutely need device-camera access, a PWA might not be the right choice since you can’t control whether your users use a browser that provides that access.

But in other cases, PWAs are a great alternative - and skipping the app stores is actually a plus since users don’t install many (unknown) apps from these stores.
