Let's face it: not every app on your Android phone is meant for prying eyes. Whether it's private documents or a discreet Tinder profile, simply hiding apps in a folder isn't secure enough. AppLock, a free Android app, changes that by using your face and voice as a biometric lock—ensuring only you can access protected apps.
AppLock scans your face and voice to create a unique security profile. Once set, it verifies your identity before granting access, adding a robust layer of protection to your device.
First, select your unlock phrase—the exact words you'll say aloud for voice authentication. Options include "Verify me," "Unlock my app," or "Open AppLock," or customize your own.
Next, test face and voice recognition in a well-lit area for best results. Use your phone's flashlight or another light source if needed. Follow the on-screen guides to align your face properly. While capturing your face, repeat your unlock phrase three times for voice training.
Tip: Optimal lighting and alignment are crucial for reliable recognition.
Set a backup method like a pattern, 4-digit PIN, or password for situations where biometrics aren't feasible.
With setup complete, customize app-specific locks.
After granting AppLock accessibility permissions, view all apps with default 'unlocked' status—no security required.
Choose from two modes: Standard lock (face or voice, plus backup) via the middle icon, or TrulySecure (face and voice) via the bordered icon. Tailor settings per app for personalized security.
When opening a locked app, AppLock prompts for authentication—keeping your data private effortlessly.
