1Password needs little introduction really, it's one of our absolute favorite apps for iOS to keep your passwords strong and secure. It isn't the lowest priced app you'll come across, though – you pay for what you get mind – but Agilebits is known for frequent sales helping folks get in for less. Now, for back to school time, 1Password 4 for iPhone and iPad is half price at $7.99 for a limited time. If you've been on the fence about picking it up, now is definitely a good time!
