KeepassDX is the modern one I’m referring to. Because of the whole Android 11 SAF/scoped storage issue, syncing to databases and clouds that use DocumentsUI (the special folders you see when your Files manager window opens) fails all the time. I’ve repeatedly lost data due to KDX not properly saving or syncing, causing file conflicts and the passwords I literally just saved to vanish the next time I unlock the database.
The developer’s response is that it’s everyone else’s fault that their apps’ SAF implementation is bad, not KDX.
I absolutely cannot recommend using it.
I’ve had it fail with most SAF locations I tried after Android 11, especially pCloud. After the database locks and KDX leaves the RAM, it often cannot find the database it literally just saved, and will often just generate a merge conflict to the location it attempted to save. As a result, after you unlock once, it can no longer unlock the database and you have to bring up DocumentsUI again.
