Applock is an android app that functions as a lock for various apps on your phone. You can install it on your device and use it to make it completely safe and secure. You can use it on your Gallery, SMS, Contacts, Gmail, Settings, Play Store, incoming calls, and any app you choose.

With this app, you can prevent unauthorized access to these apps, so even if a person wants to uninstall them on your phone, they won't be able to do it unless they have your device administrator's permission. Choose among the multiple types of locks available, including PIN, pattern, and visual password.

In addition, you may add a photo vault and set the lock screen based on the app you are currently using.
