Ratings and reviews

Five stars if it worked with more games like Geometry Dash and can slow down the game as much as u can speed it up.

Works well without root, but this will not continue with a game progress that your already playing, it's starts a complete new game. Other then that, works great.

Easy to use, good application but sometimes it go to very unstable, not responding and stopped to working specially when I use game speed in 20x, please fixed this problem
