About this app

With this app you can easily use your device with your thumb gesture.

When the feature is set, a thin gesture handle is added to the left/right side of the screen.
Swipe this handle to execute the defined functions. The default function is the most frequently used back button.

You can set various functions for horizontal/diagonal up/down diagonal gestures.
Once you get used to using short swipe gestures, you can set more features for long swipe gestures.

Depending on the size of your hand, the thickness of your thumb, or the shape of the bumper case you are using, different handle settings are provided to optimize gesture recognition.

The handle receives the user's touch event on top of the running app. It can interfere with running applications. Therefore, it is recommended to set the handle as thin as possible for gesture recognition.

If the touch interference is severe with running application such as game, you can set [App exceptions] in [Advanced Settings], then the gesture handles will not work when the app is running.

Currently available functions are as follows, and we plan to provide additional function upgrades.

More than excellent - however giving 3 stars out of 5 since there is no backup option to save current settings and configurations to later use it in for restore on same / or / other phone later. EDIT: lowered rating due to several updates but not improved this yet!

You can customize your user experience and phone interface, but it is as open as you can assign gestures to a plethora of things that fit your needs. If you dislike the bars and arrows showing around cluttering your phone, they've got you covered! You can make them transparent in the color settings. Not enough review space on how important and crucial this app is. It needs more toggles for the quick tools such as Battery saving, performance mode, etc.
