App Locker

App Locker is an effective tool that allows you to secure all applications installed on your Android device, so that only you can access them by drawing the unlock pattern.

Using the tool is simple: you define a lock pattern to the most important applications on your device. Once this is completed, whenever someone tries to erase one of the applications, a blocking screen will stop them .

The best part of the app is that you can even hide the apps so that no one knows that it is installed on your device and only so that you can see it after entering a code on your phone keypad.

App Locker is a very interesting tool with which users can add a security layer to their device.
