I use the old KeePassX on Windows, Linux, and Mac. I use KeePassDroid on Android. The password database is shared via Dropbox. Works fine.

The new fork is intriguing. Need to take a closer look.

I can attest to MiniKeePass's quality. I've been using it for years now.

I upload my keepass and key file to Dropbox (I know, I know) and then export them to MiniKeePass from the Dropbox app. MiniKeepass auto-associates the key file with the kdbx if it has the same filename as the kdbx, but with a .key extension. I can even edit the DB with Minikeepass and upload it back to Dropbox. It's not as sexy as an Android setup, but it works quite well for me.

This is my exact setup too. Perfectly happy with it. I do wish the iOS app could load my db file each time I start it but I also understand the reasons it can't so I'm ok with it.

I use this too, but I think the question was more about trust than works.
