Works great in my experience. Even supports biometric auth for unlocking your database if you'd like to use it.

It's great, but lacks yubikey support. Might arrive very soon, though, beta is already available in play store, see https://github.com/Kunzisoft/KeePassDX/issues/8

I use it on my phone and tablet. It works very well, I have no real complaints.

I use it. It seems good.

I use KeepassXC on Linux and KeepassDX on Android... and Syncthing to keep them in sync... works great.
