Surprisingly useful! Was just a neat app I put on my first Android phone and now it's a must have for each new phone.
Awesome app Works great every time
Not great. Seems like the screen orientation isn't right every way you flip the phone.
Doesn't work Keeps freezing or jumping to their website, don't download this piece of crap.
Doesn't work. Force closes every time.
No calibration Installed this app twice, but couldn't find a way to calibrate it.
