Heard of this app? Once activated, the user needs only swipe in over their selected swipe pad – from the left or right side of their screen, for example. Once they do that, they’ll find a circular tracker under their finger. This finger can be used to control a cursor on the display.
This system works with an Accessibility Service in Android. With this tracker, the user can move the cursor around the display screen & tap to click. This allows him/her to use the smartphone with 1 hand outside of apps. This app could well change the way we use our Android phones today.
