Bitwarden is excellent but i have a few nitpicks on Android.
I wish I could change the "Username" field to "Email address" because it kind of annoys me having email addresses under usernames. I'd also like to add things to favourites or folders without having to go into edit mode on every entry individually. Same with adding notes. The app has trouble following the system theme and doesn't always autofill reliably for me, meaning I sometimes have to go into the app and copy/paste my passwords manually.
Other than that, the UI is just a bit ugly compared to some other password managers,
Try Keyguard, it is open source and much nicer than the regular Bitwarden app. Do not use the version from the Play Store though, get it directly from Github.
