Locker
Your phone has secrets. Keep them invisible with the world's only volume-button triggered app lock.
Get ProtectedYour Phone Isn't
As Private As You Think
We've all been there. You hand your phone over for a second, and suddenly your privacy is at risk. Traditional locks make it obvious you have something to hide.
Nosy Friends & Family
That one friend who always swipes left when you show them a photo.
Kids Messing Around
Deleting important emails or buying games while playing with your phone.
Privacy Anxiety
The mini heart attack when someone borrows your phone to make a call.
Invisible Inputs.
Total Security.
Eliminate the risk of shoulder surfing. Oops! AppLock utilizes your device's physical volume keys as a non-visual trigger for access authorization.
Stealth Sequence
Define a unique combination of volume key presses (e.g., Up-Up-Down-Up) to bypass the lock screen silently.
Cover Interface
Protected applications remain dormant behind a static simulation, revealing their contents only when the correct tactile pattern is detected.
