What kind of mobile functionality were you looking for? The (unofficial) iOS app is pretty good IMHO and integrates with iOS’s OS-level password filling, and also supports the pass-otp plugin’s format for 2fa codes if you use that plugin. There was a decent Android client I used a while back as well, though I don’t recall the name.
