App Lock is a great tool to keep your apps private with a password or a fingerprint lock. For instance, you can use it to safeguard your apps, such as Facebook, WhatsApp, Gallery, Messenger, Snapchat, Instagram, Contacts, Gmail, and any other application from possible intruders.

With AppLock, you can choose to hide your photos and videos using a PIN or a pattern. With a PIN, you have to remember a specific passcode to open the vault. With a pattern, on the other hand, you just have to create a specific pattern and use it when accessing the app.

In order to protect your privacy, App Lock will show you an alert when someone tries to open a locked application with the wrong password.
