I rarely use the #android app store any more. If I need an app, it's probably something that's existed for the last 20 years (alarm clock, calendar, notes, project management, etc) and the only meaningful advance has been to keep the app online and showing ads/asking for a subscription. The college CS major's free APK on GitHub doesn't make app stores money, so it's logically delisted or buries.
That said, who's got the #opensource #apk for a blocksite alternative?
