Cool idea, but doesn't work. – BallTune Review

I tried this a bunch of times with two different balls and different pressures and got very inconsistent results. I also tried on different hard surfaces and from different heights and received very different results. Everything reads overinflated. To test, I let a bunch of air out of a ball until it was clearly underinflated. I tested - it read overinflated. I added air until it felt about right - it still read overinflated but actually less so... So I love the idea but the results are useless.
