I have been using KeepassX for years on Linux, Android and OSX. No problems anywhere. Yes, the interface isn't the most '2013 flat UI webapps' whatever, but it's simple, and works.

We're currently moving our office over to KeepassX for our lists, also iOS clients, Windows and for a while I had it quite happily on my java feature-phone. (Entering the master password on the feature-phone was a bit fiddly though...)
