AppLock Pro is a free utility and tool application available on Android devices developed by IQmor Dream. This app provides a Smart AppLock function to lock apps and protect privacy with password, pattern, and fingerprint lock. With the App Lock feature, you can secure your Facebook, WhatsApp, Snapchat, Messenger, Gallery, and other important apps from prying eyes. You can use a secure password for locking/unlocking apps, and even customize your lock mode to lock different apps under different circumstances. The app also provides a Break-in Alert feature that takes photos of intruders and tracks break-in attempts.

AppLock Pro also allows you to set different locked app groups with customized profiles, which is a great feature if you want to share your device with others. Additionally, the app has a Fake Cover feature that applies a fake cover to improve security. The Numeric keyboard is randomly arranged to prevent others from peeping, ensuring password security.

It is important to note that AppLock Pro uses Accessibility service, but only for reducing battery usage, improving unlocking efficiency, and ensuring AppLock Pro works stably. The app never uses it to access your private data. Overall, AppLock Pro is a great app for those who want to protect their privacy and secure their important apps.
