Connected Password Protector
Ive used a bunch of password protectors over the years on a variety of platforms. Typically, my issue with them is that they were standalone apps - and if you lost your device, you lost your data as well. DataVault offers a number of ways around this issue. There is a desktop version that can be synched via iTunes, and now they support iCloud and WebDav synching as well - so I am a happy camper.
A recent release of DataVault broke the app for my iOS 6.3 iPhone however. In the main summary (both list and tree view), the accounts were displayed with black text on a black background - which made using the app pretty near impossible. Happy to report that the newest version has fixed this problem for us iOS 6 holdouts.
