Make the app available on F-Droid

[natrius]

Hi, and thank you for this awesome project!

I was wondering if you have any plans to make the app available on F-Droid](https://f-droid.org/)? There are quite some users who prefer to avoid using Google Play and would really appreciate having it there.

There’s a helpful quickstart guide, and for metadata like descriptions, screenshots, etc., it’s generally recommended to use the Fastlane directory structure.

If publishing directly to the main F-Droid repo isn’t an option, a personal repository can be a good alternative. Here is the guide how to set one up.

Also, if you're looking for an easier first step, you might consider submitting the app to the IzzyOnDroid repo. Izzy is usually very responsive and supportive when it comes to helping developers get started with F-Droid publishing.

Feel free to use this issue to track progress if you decide to go that route.

Thanks again for your work!

Also, i think this would go hand in hand with #2 - as far as i know, APK is needed.
