Features of Oops AppLock:
Invisible Lock
When you use third-party app lock apps, then you will get a popup before opening the locked apps. This is quite annoying as other people might know that you are using certain Applock options to keep everything safe. But with the Oops AppLock, no one will know that you are using any kind of app lock. This is a very unique feature as one can use this without the other knowing.
Volume Button Lock
Traditional apps use built-in security functions to keep your apps safe. The traditional methods include the Biometric lock using fingerprint and facial recognition and also PIN and pattern lock. But with this app, you can use the volume buttons to lock or unlock certain apps. With the unique patterns for volume up and down buttons, it becomes easier to lock and unlock apps with just a few taps.
Custom Background
To let this app work without others knowing, you have to choose the custom backgrounds. This custom background will act as a lock screen. Setting the transparent or black background will help the app look like it’s stuck on the screen. While on the custom lock screen, you can use the volume buttons to unlock the apps. This way, others will think that the app is stuck or taking a long time to open, but in reality you will be using the screen to unlock the locked apps.
Additional Security
If you think this app lacks security features, then you are wrong. With additional security features like Auto-lock, auto unlock, virtual button, backup patterns, and many other things, you can use this app with full reliability.
