I thought some of you may find this interesting. it calibrates both video as well as audio.

Interesting, but as one comment on the site noted you now have to buy an Apple cable for it to work effectively, but still cheaper than a pro calibration.

Hey, cool info. I just got a new iPad delivered (ordered it with some hotel points) and am setting it up this morning. I saw this app as I was getting Netflix for my daughter but skipped over it. Knowing that it's only free for a week I am going back to get it as soon as I can shut Dora down on Netflix!

App worked as advertised though I feel it put a little too much color in the picture so i turned that down just a touch. Overall i feel my picture quality is greatly improved from the "cinema" setting on my panny. I am sure a pro calibration would be much better but for free I can't beat it. I use audyssey for audio so not going to throw the 50 bucks for a cable. If anyone does try the audio feature please let us know your results.
