Have you thought about improving your game if you could get and analyze your match statistics?
The First Serve App will help you with this.
Collect match statistics during the game — easily, conveniently, without distractions — using the Apple Watch.
Analyze the performance of your game on your own, with your coach or sparring partner.
The First Serve app will tell you how effective your first and second serves are, how many forced and unforced errors you make, and how many aces and double faults you make.
In the few seconds between points, you record the draw results. To do this, you just need to triple-tap your Apple Watch.
Or you can ask somebody to track the match in the First Server App on your iPhone.
