Smart AppLock is an application (or website) that helps protect your phone, tablet, and other mobile devices from unauthorized access. It allows you to lock your apps and data with a PIN, pattern, or fingerprint to ensure that no one else can access them. With Smart AppLock, you can also hide sensitive photos, videos, and other important files, and even lock certain incoming calls from unknown numbers. In addition to providing enhanced security and privacy, Smart AppLock has other useful features. It can enable you to block certain apps or websites, prevent others from taking screenshots of your device, hide the AppLock icon, and customize your lock screen with different wallpapers and themes. The app also has a built-in intruder selfie feature that takes a picture of anyone who tries to unlock your device with the wrong password.
