Control your phone or tablet more easily with just one hand.

Small gesture handles will be displayed on left/right edge of screen. 
By swiping this handles, configured actions will be executed.  below is default action.

- Short horizontal swipe : Back key.
- Diagonal up swipe  : Recents key. 

You can set various functions on horizontal / diagonal up / diagonal down direction gestures. As you become accustomed to using short gestures, you can set up more functions on long gestures.

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

 - Back key
 - Home key
 - Recent key
 - Menu key
 - Previous app
 - Forward ( web browser )
 - Open notification panel 
 - Open quick panel 
 - Screen off 
 - Assistance app 
 - Screenshot 
 - Floating navigation buttons
 - Pull screen down
 - One-handed mode
 - Flashlight
 - Start application
 - Task switcher 
 - Quick tools 

Depending on the size of the user's hand, the thickness of the thumb, or the shape of the bumper case being used, various handle settings are provided to optimize gesture recognition.

The handle will receive user's touch above the running app. So, as long as the gesture recognition is possible, it is recommended to set handle to be thin.

And once you are fully familiar with the use of gestures, It is recommended to enable [Quick action] on [Advanced settings].

In addition, when 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.

Experience the convenience of gestures on your phone and tablet with One Hand Operation +. 

Thank you.

Mantap 👍😊
This is great. Please add the "back" to bypass the keyboard. It's really cumbersome. Other than that it's perfect. (UPDATE: thank you for the reply. Actually, what I meant was when I use the "back gesture" that it would firstly close the keyboard and then I'm required to use back again to return to the previous page or content that I'm trying to get to. In short I need to always press back twice in order to get to the page I want. The new android 10 gestures includes this feature that once you press back it closes the keyboard and always takes you back to the other page all with just one use of the back gesture. However, I like your app functionality much better. Was hoping if maybe you can include this function into this app) I would be more than happy to donate of course

Dear customer. If you want to use the gesture on keyboard, Pleaes check "Advanced setting" - "Fit to keyboard" option. When it turned ON, the gesture works on keyboard, but it can cause slight touch interference while typing. Thank you.
I absolutley love this gesture navigation system! So much more customizable and usefull than any other nav system I use! It takes a little while to get used too and it can be overwhelming if you start with 6 gestures all at once but once you get used to it there is no going back!
Came here after softkey edge was nerfed. This is a much better solution for locking the phone with gestures, and a good app in general. There are some improvements that could be made. This should be part of the OS.
uesful but need improve, it close after I lock the screen and I want to turn it on as long as possible. I solve this by reset. perfect !
Outstanding! Should be built into the OS
This update did NOT fix issues with dark mode support. I have the regular system dark mode enabled as well as force dark mode inside the developer options. The handle is still white. It didn't used to be.
Seller 2020.02.07
Dear customer. Sorry for inconvenience. From this version we've added dark mode support for settings page. BTW, if an app supports dark mode, the force dark mode is not affects anymore, so it remained as white. Please adjust transparency level of handle setting then it will be invisible. And next update, we'll add color setting for the handles. Thank you.
Easily the best Good Lock mod and honestly the best gesture navigation.
Excellent additional control over the phone. Used to have to root and install aftermarket ROMs to get this kind of customization! Excellent work, 수고하셨습니다!
