User reviews
I have had this app since I got my first android phone over 10 years now. It works now, and has worked since I got it. It has never broke, sent me adds or messed up my handset it has worked on six or seven different types of droid. Get it!
App works after calibration Dev doesn't ask for unreasonable permissions. Good man!
Calibration is 1.72 on Galaxy Nexus Android 4.1 Jelly Bean
Nice.
Does just what you think it does.
Great! Calibrate 1.03 for Motorola i1. New phone; still great. Calibrate 1.5 for Atrix.
