The secure NQ Mobile Vault for iPhone (pictures)

NQ Mobile Vault's coolest features, SecureCam, Break-in Monitor, and Fake Vault, are all available to premium users.

It's easy enough to add photos and videos to your secure vault. Unfortunately, though, the app doesn't automatically delete them from your Gallery.

Hold your device's camera up to a solid surface or the palm of your hand to pull up Vault's secret keypad. SecureCam is a premium feature available only to paying users.

Enable Break-in Monitor (premium feature) and Vault will take a photo of anyone who enters an incorrect password.
