Did you tried UnCiv ? Feels like garbage to play to me. Maybe it is just too complete for my mobile game sessions… (And I don’t really like civilisation turn based games anymore.)

Mindustry (factorio like) plays badly on mobile (everything is too small, touch is not precise need to zoom a lot but you don’t see anything/can’t build long belt that way). But now I want to play it on PC.

On the other hand, Feudal Tactics is really nice to play on mobile.

I know simple fossify apps are appreciated by the comminity. I have yet to try them. I like Etar as a calendar. It is also on FDroid
