AppLock is a free utility application available for Android devices developed by Manya. It is designed to secure your personal data from unwanted access by locking photos, videos, social media apps, and other private data with password, pattern, and fingerprint lock (if your device supports it). With AppLock, you can keep your personal data safe and protected from everyone.

One of the main features of AppLock is its ability to lock gallery, message, social media, and email apps with fingerprint, PIN, and pattern lock. You can also lock the recent apps page so that no one can see the content of recently used apps. Another useful feature is the ability to re-lock apps immediately or after screen off. The app has a beautiful and simple UI that makes it easy to perform any task.

When you install a new app, AppLock automatically locks it. After unlocking, you can even uninstall the app. To set your password for the first time, open AppLock, enter your PIN code, and confirm it. You can also enter your lucky number for password reset or pattern in case you forget it.

Note that for Android 5.0+, you must allow AppLock to use usage access permission. Find AppLock in the settings and allow usage access to use the app effectively.
