THX Calibration app for iphones and ipad
THX app is free atm which is a good way to calibrate the colour brightness contrast and even the surround sound. It apparently very good however as I was a first adopter ipad owner mine cant run it as it need the camera. If you have and Ipad 2 or later must be worth a download.
