 The app has 2 build types: debug and release with minor differences between both builds. [`Stetho`](http://facebook.github.io/stetho/) for example is only enabled for debug builds. And [`Timber`](https://github.com/JakeWharton/timber) to log warnings and errors as Crashlytics non-fatal crashes in release builds.
 
 We also use different app icons for debug and release builds and you can keep both builds on your device and run them side by side.

 The app is 100% [Kotlin](http://kotlinlang.org) and we think it is better to keep it this way.
 
 We use [`Koin`](https://insert-koin.io) which is a lightweight dependency injection framework to manage all dependencies. And [`Kotlin Coroutines`](https://kotlinlang.org/docs/reference/coroutines-overview.html) for asynchronous work. We also use `Kotlin Coroutines` with [`Room`](https://developer.android.com/topic/libraries/architecture/room) and [`Retrofit`](https://square.github.io/retrofit/).
