About this app

**The Only Truly Invisible App Locker**

Unlock your apps without anyone seeing how. No visible PINs, no on-screen patterns - just secret volume button combos and invisible edge buttons.

**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

---

🎯 **HOW IT WORKS**

1. Set up your secure PIN (4-6 digits)
2. Add a volume button pattern for quick access
3. Select which apps to protect
4. Done! Apps are now invisibly locked

**To unlock:** Press your secret volume pattern or tap invisible buttons. No visible UI appears!. Flick screen to enter PIN.

App is wonderful, the only problem is when I turned this off then also it keeps my apps locked with the images I set. For some reasons I do not wish to lock my apps(which I locked earlier), and therefore turned off Oops! AppLock and also unlocked the previously locked apps, but this is still keeping my apps locked. Is there any way to get out of this or do i need to uninstall this app for the time being untill I really need this? Please help. Oops! AppLock is however, a wonderful product. 👌

This application and your ideas are good. But I have experienced some security issues. I locked my 'File Manager' with this application. When I try to open it, it will only open after I press my volume key up to a certain time that I fixed. But if anyone tried to search any files keywords, then it will show the concerned file and it can be viewed or played if it as a video file. Remember...it is a application locker. Then, how this type of files are protected...?

This Apps is good, its worth using it. I've tried many other Apps but non other Apps can be compare with this. But one setting needs to be update, ie. APP LOCK SETTING. In SCREEN LOCK , we have Screen lock style ( Default, Black, Transparent and Custom ). But this is not applicable for APPS LOCK , and I want this SETTING in Apps lock too. Besides VIRTUAL BOTTON is too limited, if we can place on our own desired position will be Awesome.
