I like it!

This app was needed to check out DB levels with dishwashers that proported to be silent at 40DB. So without having to buy expensive additional equipment, I bought this app to check that advertisement. Checking it against several known levels, it appears to be quite accurate, but Im not positive on that. But checking it against those dishwashers I quickly noticed that some were as advertised, some were not. So, I think its worth the price, by far. If you need something like this, try this out first.
