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.

Could you please give the "Task Switcher" some love with UI customisation, kinda like how you can customise the "Curved Line". It's looking a bit dated and I use it everyday for about 6 years. Please and Thankyou. Love this accessibility app with big screens
