1Password is by far one of my most-used apps and is a must-have for any iPhone or iPad owner. This is my go-to app for making life easier on the web especially when we have billions of passwords to remember. It’s also great for filling forms and saving any important info securely, with various sync options including Dropbox and iCloud.
