Amazing idea!

The way the app works is really ingenious and makes total sense! I only got to try it once, so I still have to test it further, but my first impression is very positive. Its really easy to use and appears to be accurate. I just would like to try it many more times because on the only serve I tried to measure it gave me 110 mph…. although I felt very happy about it I know I need to try it several more times, as I didnt think (and still dont) I could serve that fast.
