Applock 2021 is a free Android app developed by Carbon Apps that allows you to secure all the apps on your phone. It works similarly to other app locking apps but performs better in many cases. With Applock 2021, you can quickly encrypt your SMS messages, gallery, camera, contacts, and other mobile apps to keep them safe from unauthorized access.

One of the most impressive features of Applock 2021 is its powerful intruder catcher that takes a snapshot of anyone trying to access your locked apps without your permission and provides it to you. The app requires device administrator permission to function properly, which you must grant during installation.

Overall, Applock 2021 is a reliable and user-friendly utility tool that provides an extra layer of security to your Android device.
