Secret Lock Photo+Video Manager - Private Vault to Store Photos off the Cloud for iOS

Lock offers a secondary privacy layer for photos and notes on your iPhone, and it does so with a slick, easy-to-use interface. The app doesn't try to do too much and yet offers enough depth and options to be a very useful tool for anyone with private photos and notes they'd prefer to keep that way.

When you load Lock for the first time, you need to choose a pin. Every time you load the app after this, you'll need to enter this pin, so be sure it's something you will remember. From here you can add new images from your photo library or camera or you can add notes with the note interface. Everything you add in this way is protected in the app's interface by your pin number. Options are limited from there, though you can share directly from the app, transferring images to your camera roll, Facebook, or e-mail. You can also copy the images for other uses.

In its free form, Lock is a useful photo and note protection app. It looks very good and is fun to use. If you choose to upgrade, you can also access private video and note-saving, category creation, and removal of the ads. Because of how quick and responsive the app is, how smoothly it runs and how well designed the interface is, the upgrade is a worthy addition if you need an app that can protect your personal information with added security.
