Obtanium is just awesome. Can't believe i went this long without it.
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/
Pair Droidify with Shizuku (also on IzzyOnDroid) and you've got automatic updates.

Oh nice I'll check that out!
How does Droidify compare with Obtainium?
Droidify is more like a really nice looking frontend alternative to F-Droid. But it also has other sources it pulls from like IzzyOnDroid and stuff like that. Obtanium can pull from F-Droid and IzzyOnDroid and such but you have to know what you're looking for, there isn't really any browsing aspect afaik. Obtanium can also pull directly from a GitHub page. (Droidify may also be able to do this by adding the repo to the sources but I haven't tried)
Personally I use droidify for everything I can get on F-Droid and IzzyOnDroid and obtanium for the few things that just have a GitHub page
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.
Thanks dor the F-Droid repo! I've added it.
