Keepsafe App Lock

Keepsafe App Lock is a simple app that puts a virtual lock on any app installed on your Android. With it no one can access your WhatsApp messages, see the photos in your Gallery, or sneak a peek at your Contacts.

The way the app works is very simple: after installing Keepsafe App Lock, you can create an unlock pattern or password, after which point you'll need to enter the pattern to use any of the apps you've chosen to protect. And if anyone tries to uninstall an app, a window demanding the unlock pattern will pop up first.

Keepsafe App Lock's main interface is very intuitive. You can see a complete list of all the apps installed on the device. All you have to do is tap the apps you want to protect to add them to your security list.

Keepsafe App Lock is quite a useful app thanks to which you can add an extra layer of security to your Android. No more worrying about leaving your device with friends, since they'll no longer be able to access anything they shouldn't.
