You can try the Bitwarden Beta apps - they're the new native apps. They're quite a bit better on the eyes.
If that doesn't work for you, try Keyguard.
Keyguard is proprietary unfortunately
Is it? It's on github - I didn't notice any proprietary blobs.
It it's not "open source", it is "source available" (GitHub: The source code is available for personal use only). You can see source, but cannot modify or fork project.
P. S. I don't understand why it is not licensed under FOSS license. You can add open source app to Play Market and even sell it.

Unfortunately, beta channel is GooglePlay exclusive, if I'm not mistaken.
If that doesn't work for you, try Keyguard.
As it's already mentioned, Keyguard is proprietary.
You can use obtanium to get beta directly from GitHub
Oh, I didn't know that. Thanks!
