Is your second serve actually getting better? Now you'll know. Serve Tracker turns a bucket of practice serves into real stats, one button press per ball, without ever looking at your watch. Hit your serve, press IN or FAULT, and reach for the next ball. The app handles the rest. ONE PRESS PER BALL - START = in. BACK = fault. That's it. - Fault on your first serve and the app moves you to your second serve automatically. Fault again and it logs the double fault for you. - Hit the wrong button? DOWN undoes the last ball. EYES ON THE BALL, NOT YOUR WRIST Every result has its own vibration, so you always know what was logged: - Short tick: serve in - Long buzz: fault - Double pulse: double fault BUILT FOR A SWEATY COURT - BACK never exits by accident. You can only leave through the menu. - The touchscreen is ignored, so a damp hand or wristband can't log a phantom serve. - No phone needed during practice. THE NUMBERS THAT MATTER - 1st-serve %, 2nd-serve %, double faults and double-fault rate - Points played and total balls hit - A summary screen every time you save SEE YOUR PROGRESS - Saved as a tennis activity with heart rate and duration, with your serve stats attached in Garmin Connect - On-watch History: a chart of your 2nd-serve % over your last 12 sessions, your last-5 and all-time averages, and every saved session Hold UP anytime for the menu: Resume, Undo, History, Save & Exit, or Discard & Exit. Stop guessing. Grab a bucket, start serving, and watch your second serve improve.
