Features & Capabilities

Knock Lock Screen - Applock offers a unique and secure way to unlock your device while protecting your privacy. Instead of exposing your PIN or swipe patterns, simply tap a secret knock sequence on your screen to unlock — completely invisible to onlookers. This innovative approach confounds intruders and keeps your device safe from unauthorized access.

Features include multiple lock types such as Knock Lock, Pattern Lock, and Time Password Lock. It prevents accidental calls and unauthorized use with customizable knock positions and supports both 12-hour and 24-hour formats. Knock Lock also includes options to enable or disable unlock vibrations and sounds, consumes minimal memory and battery power, and boasts rich graphics for a clean user experience. To support double-tap locking, the app requests device administrator permission without intruding on your private data. This extension is perfect for users seeking advanced device security with an easy, discreet unlocking method.
