AppLock PRO is a smartphone app that lets you lock applications and photos with fingerprints, passwords, or patterns. It’s a utility tool that allows you to limit access to your private documents and the programs that you install. By setting a passcode or locking your apps with a unique pattern, you can keep your personal files safe. Additionally, you can do the same thing using fingerprints on supported devices.

After you install AppLock, you can choose to lock either your entire device or a specific app, like WhatsApp, Facebook, Messenger, Instagram or any other app you want. You will only be able to open an app or photo if you have the correct credentials.
