TennisCounter is a match tracking app built for young tennis players and their parents. Finish a match and the numbers are already organised — no more relying on memory. ONE-TAP SCORING, READABLE COURTSIDE Huge game scores you can read from across the court. Just tap "My point" or "Opponent's point" — the serve row follows whoever is serving. Winning and losing a point use different sounds, so you know what happened without looking at the phone. EVERY COMMON FORMAT · Age-group (early rounds): 1 set of 6, 7 at 5-5, tiebreak at 6-6 · Age-group (final & semi-final): 1 set of 8, 9 at 7-7, tiebreak at 8-8 · Domestic: 4 or 6 games, No-Ad, sudden death · Official: best of 3 or best of 5, with or without advantage · Custom: set your own games per set, match length and tiebreak target FULL PERFORMANCE ANALYSIS Point rate, first-serve in, double-fault rate, hold serve, break conversion, points on serve and return, and spin success — seven metrics, each compared against your own history so progress is obvious. AI COACH After every match an AI coach reads the actual numbers and gives you 3–5 specific suggestions covering technique, tactics, mental game and physical preparation. Not generic advice — it responds to what happened in your match. FULL MATCH REPORT Set-by-set scores and every statistic in one place. Share it with a coach or a parent in one tap.
