Sideline - Tennis Coach

A tennis coach in your pocket. Set your phone up behind the baseline, tap Begin, and play. Sideline follows the court, both players and the ball as you play, on the phone.

YOUR GAME, SHOT BY SHOT
Every shot named, with its speed and where it landed, in or out. Points and rallies counted for you, and every session kept.

YOUR OWN COACH
Sideline follows your body through every serve, forehand, backhand and volley and scores it against a model swing, so you know what to work on. Scores at heysideline.com.

HOW HARD YOU PLAYED
How far you ran, how fast, your longest rally and the points you played, after every session. No watch needed.

YOUR VIDEO STAYS YOURS
The analysis runs on your phone. Your video leaves it only if you turn on "Save your sessions", and no other user ever sees it. Sign in with Google; you must be 18 or older.

Works best on a recent, high-end phone.
