What Is AppLock – Fingerprint?
AppLock – Fingerprint is an Android security application that allows users to lock specific apps using a PIN, pattern, password, or biometric authentication such as fingerprint or face unlock (depending on device support).
The main purpose of this app is to prevent unauthorized access to your personal apps like WhatsApp, Instagram, Facebook, Gallery, Messages, Contacts, and even system settings. Instead of locking the entire phone, this app gives you full control to lock only the apps you want.
This application is especially useful for people who often lend their phones to others or want to keep certain apps private. It works quietly in the background and provides a simple user interface that even beginners can easily understand.
