1Password (alias: OnePassword ) is a prestigious cross-platform (Windows, Mac, Android, iPhone, iPad) personal passwords managing application developed by AgileBits from Canada. It has been evaluated as one of the Top 10 best apps by Apple's App Store.
In AppNee's opinion, the real king in the password managing field is KeePass (just a bit rough). But taken together, no similar application can replace RoboForm (AKA: AI RoboForm). This includes the most popular and beautiful 1Password, as well as the LastPass with best cross-platform support and fast growing users.
