I tried bowser before. I didn’t find a good use case for it. It had a signer in it but I could only use it inside its own browser

It works as an nsec bunker too, you can log into desktop apps using your phone. On Android it is also a drop in replacement for Amber, keeping your key in one place, I'm not sure how that works on iOS though.
Dashu deserves more credit, his apps are simple to use and have a lot of features.
So there’s Aegis, Nowser and Nostash on iOS. Cool
