Thanks @gentooza

@sauloperez is trying to update our Android and IOs apps to the last EXPO SDK here https://github.com/sauloperez/my-app after that we can move this changes to this repo.

I have no idea if it's possible to build the app also to F-Droid, @gentooza could you help with that?

Yes, I guess it's posible, but the app is not licensed just now, as I already asked in #11
If it's not licensed then it's closed source software, so it can't be published in f-droid :-/
