AppLock Master

AppLock Master is a top-rated free app lock extension designed to secure your Android apps through multiple locking mechanisms including PIN, pattern, and fingerprint (supported on Android 6.0 and Samsung devices). It offers advanced features such as a random keyboard, time-based passwords, invisible patterns, and customizable pattern sizes for enhanced security.

Beyond locking individual apps, it secures incoming calls, recent tasks, Wi-Fi/Bluetooth switches, app installations/uninstallations, and third-party apps. The extension supports temporary unlock functionality, enabling you to avoid re-entering passwords frequently by offering delay lock options and single-password unlocking for multiple apps. Additional protection includes cover disguises like fake fingerprint scanners and fake force close dialogs.

For privacy, AppLock Master includes an intruder selfie feature capturing photos of unauthorized unlock attempts. It also supports theme customization, background settings (including gallery images, system wallpapers, transparency, and blur effects), and lock screen animations. The app’s orientation locking and icon hiding add further layers of user convenience and privacy. With comprehensive support and uninstall prevention, AppLock Master is a powerful solution for protecting your mobile privacy.
