Cross-Platform App vs. Native App Development in the ordinary life of a dev
What we do at Motius spans from simple IoT prototypes for our office to complex software solutions for our clients. In most cases, this includes developing a mobile application. The reason for this is that mobile phones accompany us everywhere, so we like to be able to do everything with them. If you think about it, it’s only natural to have an app be part of a project in most cases. Motees love mobile development and we believe it’s very practical to be able to control our hardware prototypes via an app, so mobile development is indeed a must for us.
An example of a project that is worth mentioning is our drunk detector app, which is actually a prototype we built in a weekend at our office. You attach an infrared camera like FLIR to the phone, look into it and the app will tell you whether you are drunk or not. This application we developed natively for Android, simply because the developers were using Android phones, so we didn’t see any benefit in targeting iOS at the time.
But is this the case for all apps we develop?
What do we do when a client comes to us and wishes to build an app? The first thing we typically think is: let’s make it cross-platform. Why? Because we can. We found out that, with experienced developers, implementing a cross platform mobile application takes roughly the same amount of time as it would take developing a native application for only one platform. And if a project doesn’t require specific hardware or APIs, which are not available on both platforms, then why not kill two birds with one stone?
Like many others, most of our developers are self-taught in native mobile development and are quite fluent in either Android applications written in Java or iOS applications written in Swift, or even both of them. There comes a time though, when you want to rapidly prototype a solution for both platforms, without having to write the entire code twice. There’s many different ways to do this and all have their pros and cons. At Motius the framework of choice for doing this is React Native.
The React Native experience
React Native spawns off ReactJS, which was originally intended to help developers in building web applications (we’re talking about one of the top starred projects on GitHub). One day Facebook decided to apply this concept to mobile development as well, which is where the React Native adventure starts.
Last but not least, the deployment. It just works. Be it an emulator/simulator or a real device. One command in the terminal and the app is installed and running. And it looks the same on both platforms.
Of course, it’s not always roses, there also happen to be some downsides. As a developer, there is a time when you need to do something that is not supported or included in the base framework, so you have to look for a suitable library to help you out. There’s tons of libraries out there and it takes some time to find the right one. All libraries are open-source and can contain Easter bugs. Fun fact: we noticed several times already that some bug reports had been open for months and in the end, it was up to us to fork the libraries and fix those bugs ourselves, or add some functionality we needed (this is just one example). To be completely honest, every now and then working with the framework feels like testing a beta version. Also, in some extreme cases, a library you are looking for doesn’t exist at all or doesn’t cover an edge case which is required in your app. In that case the only option is to resort to native modules, but that’s very rare. The size of the community, however, is a big plus and makes us confident that the framework itself will keep getting better.
At the end of the day, it’s really fun to be able to quickly prototype an app and have it working right off the bat on any phone, with good performance and most importantly, a lot of satisfaction 🙂
Do we miss native development? Definitely! But mostly because we haven’t used one of the new OS versions before and want to play with them in order to learn something new (isn’t that in our DNA, after all?). Cross-platform development in general really makes the entire flow more efficient and opens up more possibilities. We really like it and will continue exploring these new possibilities. Who knows, maybe next up will be a cool framework for cross-platform development for wearables?!
