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.
