Calculator: I’m using the one that came with grapheneos, which I think is the AOSP calculator. It meets all of my simple calculator needs

Camera: GrapheneOS camera for qr codes and videos, because the modded gcam app (not FOSS) I use doesn’t support either. I like that it shows you the qr link after you scan it instead of instantly opening it. It doesn’t connect to WiFi if you scan one though it will show you the name and password.

Calendar: Fossify Calendar. It’s a fork of simple calendar. It has my favorite calendar interface and works with Davx5 to sync with CalDAV servers.
