First of all, let's take an example how the entire app works. If you put the picture with lamps on your lockscreen, it's easy to remember the gesture - connect the lamps, draw a circle around the light and point in the middle of the other one. Teoretically, nobody has any chance to unlock your phone.
This app also comes in a pro version containing some extra features like:
- Screen Lock Delay
- Tasker Plugin
- Lock Control Widget
- Time Display
- Theme Color
- Greater Allowed Number And Combination Of Gestures
- Widget Locker Support
- Music Controls
- System Wallpaper Cropper
- Multiple Gesture Sets: Cycle between multiple sets of images and gestures every unlock
- Missed Calls and Unread SMS Counts
If you like the app, head over to pro version to support the dev!
For experimental uses, there also exists a beta version with some extra features and improvements, you can get it HERE.
