I have been using DataVault Password Manager for several years and I am pleased with the app. It is worth the upgrade to DataVault Premium for the extra features. I use Dropbox to synchronize data between my Mac, iPad and iPhone and it works very well. The only thing keeping me from giving this app 5 stars is the lack of iCloud synchronization with my Mac.
