Swipe Back is an Android app developed by coolAce that allows users to easily use the back button with just one hand. With this app, you can lightly swipe the set area to go back to the previous screen. If you don't release your finger, the back button function will be executed repeatedly.

To use Swipe Back, you need to turn on the accessibility service and select it in the service item. The app uses the AccessibilityService API, but the developer assures that they do not collect any personal information through accessibility services. The accessibility permission is only used to register the swipe actions of the user, so that the back function will work.

Overall, Swipe Back is a useful and convenient app for anyone who wants to make it easier to navigate their Android device with just one hand.
