WHY OOPS APPLOCK IS DIFFERENT
Unlike traditional app lockers with obvious keypads, Oops AppLock keeps your unlock method completely secret:
-
Volume Pattern Lock - Unlock using volume key combinations.
-
Invisible Virtual Buttons - Tap hidden buttons on screen edges.
-
Transparent Lock Screen - Looks like the app is already open.
-
Disguised Icon - Appears as a notes app in your drawer.
-
Intruder Selfie - Catches snoopers with front camera photo.
Someone watching over your shoulder literally cannot see how you unlock.

POWERFUL PRIVACY PROTECTION
- Lock any app - WhatsApp, Gallery, Gmail, Instagram, banking apps.
- Multiple unlock methods - PIN, volume patterns, virtual buttons.
- Intruder Detection - Photo capture on failed attempts.
- Auto re-lock when screen turns off.
- AES-256 encryption for your PIN.
- Zero data collection - your privacy stays on your device
