So I just updated Liftoff manually by downloading the APK from GitHub, however I feel like doing so isn’t the best way to keep the app updated outside of installing the app from the Play Store. I had heard of a way to keep it updated automatically with some app or service but I can’t remember the name. What is the best way to keep this app updated?
I use the droidify app. Which uses various f Droid and other repos to manage apps. Liftoff is available on the IzzyOnDroid repo https://apt.izzysoft.de/fdroid/index/apk/com.liftoffapp.liftoff
Droidify is available on F-Droid: https://f-droid.org/en/packages/com.looker.droidify/
As already mentioned, you’re probably looking for Obtanium. There’s also APKUpdater, which hasn’t seen updates in two years but has a 3.0 branch ready for testing. (I haven’t personally used it.)
For Liftoff specifically, I’ll add that it’s available in the IzzyOnDroid repository for F-Droid, which is useful if you’re already using F-Droid for anything else.
