Overview

AppLock is a mobile app that provides protection for your privacy by locking other apps on your device. It can lock social apps like Facebook, Instagram, and WeChat, as well as system apps like Gallery, SMS, and Contacts. AppLock offers multiple lock options, including PIN and pattern locks, and has a photo vault to keep your photos and videos safe. It also supports screen lock and has a variety of themes to choose from.

In addition to app locking, AppLock provides real-time protection by monitoring new installations and app updates to avoid potential risks. It also has a photo vault to encrypt and hide your photos and videos, and an intruder selfie feature that captures photos of anyone who enters the wrong lock screen.

AppLock can also lock 3G, 4G data, Wi-Fi, Bluetooth, and new apps, and prevent uninstallation. It has an easy-to-use and user-friendly GUI.

To use AppLock, you need to download and install the Transparent Pattern Lock, enable the lock in settings, and set your pattern. If you forget your password, you can reset it by entering your lucky number and creating a new password. For Android 5.0+, you need to allow AppLock to use usage access permission.

If you have a phone with a fingerprint reader made by Samsung or running Android Marshmallow, you can use your fingerprint to unlock AppLock. AppLock also has a live theme feature to make unlocking apps more fun, and regularly launches new live themes. You can contact AppLock at [email protected] .
