It depends. Are there any apps you want to know about specifically? I'm running CalyxOS right now and can try.

My banking apps work fine, surprisingly. And some Google (Gmail, Phone, and Fi) apps too, surprisingly, but not all (eg Meet, Messages, and Fit)

Mostly just Signal, and a good maps app. TOPT apps I'd assume is readily available. The only other app I regularly use otherwise is ErgData from Concept2, but they offer the APK file for download.

I do have a local payment app, which would be nice to not lose, but it's not a hard requirement. The number of apps I use these days are surprisingly low.
