AppLock is a free security tool developed by Pix Team for Android devices. This app helps protect your phone from unauthorized access by locking your applications from public access. With a complex password, AppLock can hide all types of apps such as social messenger, gallery, music player, video player, and all games with a secret lock or password.

One of the features of AppLock is the ability to protect any app using a password or pattern. It also includes a photo and video vault that allows you to hide pictures and videos. You can even lock incoming and outgoing calls, prevent app installations or uninstalls, and lock system settings.

The app is very easy to use. After installing AppLock, you get a list of all installed applications in a nice GUI on your device. You can select a password for your application software and pick individual apps from the list view of apps for password protection.

With AppLock, you will never worry about kids changing your data or games, exposing your privacy and private data to others, or private data in some apps being read by someone else.

Overall, AppLock is a great app that provides an extra layer of security to your Android device. It is easy to use, and its features are very useful for protecting your privacy.
