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.

The app seems simple until you explore the various options that not only 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 as an android user who wants to use my screen to its full capacity.

UPDATE - I misunderstood how the transparency slider worked because there is no change until you leave the settings page. Now that I understand how to set it properly, I have to declare this app is Perfect! This should be a standard feature on all Samsung phones! Original--- I love this app. it should become standard for all android phone. the only reason i have not given 5 stars is because i can't turn the white bars completely off. it is distracting when i watch a movie. please consider this!

Dear customer, Please set the "Transparency level" slider as MAX, then the white bar will be invisible. Thank you.

Edit: After fixing fit to keyboard issue, app is just as perfect as it was before. Thanks for listening and fixing! ************************************* Why was the fit to keyboard option removed? Now I have to stretch my fingers to exit out of the keyboard, as they are now raised from their normal position. It used to be a simple swipe back out, but now it's such a task. Please fix.
