Stocks/Yahoo Finance alternative app for Android

Any recommendations for a private alternative to the Yahoo Finance app to monitor stocks on Android?

I saw this OpenBB once:

Its not android though, sorry. I know it makes sense to be on a mobile platform. But at least it is something.

A quick search does lead to this app.

F-Droid says that it relies on a non-free service. This is most likely something like Yahoo Finance data.
