What is this?

Currency exchange rate converter that uses a public Revolut API for the exchange rates

What did you use?

This project is built purely with Kotlin with an MVVM design pattern, Retrofit to fetch the API data, Room to store said data, Koin to manage dependencies and Rx to manage asynchronous tasks.

Why did you choose to do that?

I'm pretty sure you already know why I went with Kotlin. I mean, come on.

MVVM is just more fun to play around with than MVP, even though I can't really say it's inherently better (I simply love LiveData).

Retrofit is my go-to tool when it comes to getting data from the internet. Easy to use and pretty straightforward!

Room needs no introduction. If you need a local database you simply go for Room.

Koin... the eternal dilemma with Koin and Dagger. Honestly I just went with Koin because I feel like it is designed for this kind of jobs. Small apps without a lot of dependencies. Dagger is superior in every way, but it would be overkill for this project.

When it comes down to Rx or Coroutines, I always choose Rx simply because that's what I have experience with. Coroutines are very good, but I feel like I have more control with Rx.

How does it look in action?
