App Lock is a security tool for Android devices that will help you protect your privacy by locking your applications with a PIN or pattern. This tool is not only capable of locking your applications, but also of preventing other people from accessing them.

In order to achieve this, App Lock has the ability to monitor and block the installation of new applications. It can also block the creation of new folders in your device’s storage, which means that nobody will be able to access your private data.

App Lock is capable of locking both the current application and all the future installs. This means that even if you uninstall the app, it will still keep the locks on the applications you have locked.

The tool is quite easy to use, but you will have to take the time to learn how to use it.
