Release source and F-Droid

[rugk]

It would be great to see this Android app on F-Droid!

F-Droid is an Android app store specifically for free/libre open-source apps. It would be great if your app could be released there, as it is the number one for getting FLOSS Android apps for many people.
F-Droid also builds all apps from source (optionally even reproducible), so downloads from there can be trusted.

Of course this would require you to open-source the app. But imho that would be a good thing actually, and for a free app I see no disadvantages. And you could feature the app and this the brand on the store too, as explained below.
At least one app could be there to hint to the other apps.

The app developer FAQ or the quick start guide may help you to get started.

BTW a release on F-Droid could also bring some (more) popularity (in case that is intended), as it will show up in the app (new apps are featured there).
