I'm using pass on OS X and Linux (synced via Dropbox). It's an open source terminal based password manager and uses GPG under the hood. I don't have a mobile client, but the amount of times I've needed a password on mobile when I don't have my laptop around are far and few between. The documentation was a bit lacking when I started, so I wrote an article with instructions: http://www.stackednotion.com/blog/2012/09/10…
The neat thing with yubikey neo is that I can use it with android phone using openkeychain and nfc. This pairs neatly with an app named password store that syncs my pass-database using git + ssh leaving my private key secure.
