I can't think of anything that is going to beat KeepassDX. They have keyboard integration, can be unlocked by biometrics, and I have it set up to automatically sync my database to my Nextvloud server.

The verson of the Signet mobile app copies passwords to the clipboard, which is suboptimal. Beyond that, it doesn't even install on the latest version of Android and I haven't been able to get it to compile.

I'm looking for an Android dev who wild be willing to volunteer a few hours to get it fixed, if you know anyone.

There's also browser integration via browser add-ons, but I don't think anyone is currently using them (I know I am not). I'm already stretched thin, but testing them out is on my list.
