What is it about?

The App Lock application is one of the best app lock solutions for Android devices. It protects your phone against unauthorized access by other people, and also prevents anyone from accessing your personal photos, videos, and other data. With the fingerprint and pattern recognition, you can be sure that the person who gets access to your device is the person you want.

How do I use it?

First, download the App Lock application from the Google Play Store. After installing it, you can start using it right away. To use it, you just need to create a pattern, fingerprint, or password. You can set a security question to recover your password if you forget it. You can also set a random keyboard layout to make it harder for others to guess your password. The fingerprint option is the best one for those who have a fingerprint scanner on their device.
