Based on comments by a few new users to the forum, this occurred to me. Maybe I’ve missed an explanation somewhere, but I couldn’t find it.
Why isn’t a copy of the APK available in GitHub under the Assets section of each release?
A couple of my other favourite apps have the APK in the Play Store, F-droid, and GitHub. Especially for those who want the latest but don’t use the Play Store and because F-droid is often slow to update.
