Since this app updates so often and it takes so long for app stores to have the latest update available, it would make sense to have a link to Obtainium right next to the links for F-Droid, Google Play, and the GitHub release page. Slide for Lemmy does something similar, though it is arguably more important there, as the app is not available on any store yet.
I have the project watched on github. Set it to custom, and releases. Whenever a release comrs out you’ll get an email. I usually get it withing a minute or two of a new release
