Barely any instructions. Relying on a human to tap a button in perfect synch with a server hitting the ball and receiver returning leaves waaaay too much room for error. Then you have to approximate distance traveled etc. Might as well use a stopwatch and do the math. I expected this would take advantage of the user’s camera to analyze live in real time using sound and visual input. Pretty much a waste of time.
The app requires you to select the distance between the server and the receiver from pre-programmed lengths. The maximum is 66.5 feet. But a tennis court is 78 feet long, and often receivers stand well behind the baseline.
For a free app, it’s nice. Lots of room for human error, since you can’t slow videos down or go frame by frame. But it can give a decent general idea of how fast a serve went if you do it multiple times per serve. Can’t complain - works better than some of the paid apps.
