Everything you need. Nothing you don't.

Instant Biometric Lock

Fingerprint and Face Unlock open your apps in a blink. Fall back to a 4-digit PIN anytime.

Stealth Mode

Hide the icon or disguise it as a calculator or clock. Nobody knows it's there.

Advanced Foreground Service

Protection runs continuously in the background, locking target apps the instant they open — no pauses, no lag.

Wrong PIN? The front camera snaps a photo of the intruder so you know who tried.

Security & permissions

Every permission, explained.

App Locker Pro asks for only what it needs to protect your apps — and everything it processes stays on your phone. Nothing is uploaded, ever.

Usage access

Android requires this so the app can detect when a locked app opens and lock it instantly. It never reads or records what happens inside other apps.

Biometric authentication

Used only to verify your fingerprint or face at unlock. Your biometric data is handled by Android itself and never leaves your device.

Camera

Only for the optional Break-in Alerts feature — it snaps a photo after repeated wrong PIN attempts. Photos stay in your device's local storage.

Foreground service

Keeps locking active and reliable in the background so protection never pauses. It's event-driven, so it barely touches your battery.

Reviews

Loved by privacy-first users.

“Locked my WhatsApp and banking apps in under a minute. The fingerprint unlock is instant — doesn't feel like a lock at all.”

Dinesh R.

“The intruder photo feature is brilliant. Someone tried my PIN twice and I have their face on record.”

Amara K.

“Hiding the icon as a calculator is genius. Battery impact is basically zero on my phone.”
