Keypad Screen Lock

The Keypad Screen Lock app simulates a screen lock which can be unlocked using a pin code. Pick a pin code when first starting the application then use the code to unlock your phone or tablet.

Best feature, after 3 or more failed attempts(based on the selected option), the app will set the alarm off!

This should not be used as a primary security measure for your device rather as a backup to your native lock screen.
