Nice idea, bad implementation. The values are by no means correct. I tested with Iphone 4, ambient is mid 50s, typing this review is 64db on the Max, the peak shows in the mid 80s, considering I am not pounding the keys I would say that the numbers, graph, and common sense all indicate diffrent results. Nice app if you dont need any kind of accuracy.
