Store description excerpt
TennisWall — Measure serve speed, count shots, and track your wall training using only your phone. --- TennisWall turns your phone into a real-time tennis coach. Place it on the ground near the court wall, hit a few balls, and let the app measure your serve speed, count every shot, and track your consistency — no sensors, no wearables, no subscriptions. --- HOW IT WORKS TennisWall uses your phone's microphone to detect ball impacts. When you hit a ball against the wall, the app captures both the racquet strike and the wall rebound, then calculates speed from the time between them. Every rally is automatically saved so you can review your progress session after session. --- KEY FEATURES - Serve Speed Training Measure your serve speed using nothing but your phone. Get instant audio feedback after each serve and push your personal best higher with every session. - Wall Consistency Training Train solo against any tennis wall. TennisWall counts every shot automatically, tracks your longest rallies, and helps you build the rhythm and endurance that match play demands. - Shot Speed Tracking Every stroke is timed from hit to wall and converted to speed in your preferred unit — m/s, km/h, or mph. Track your fastest shot, monitor your average, and watch the numbers climb. - Hands-Free Audio Feedback Connect a Bluetooth headphone and hear real-time announcements while you play: shot speed, shot counter, serve speed, and end-of-rally summaries — all without touching your phone. - Training History Every session is saved locally. Compare today's numbers against past training, review serve speed trends, monitor rally length improvement, and identify your best-performing days. - Advanced Tuning Calibrate detection for any court environment: • Sound Sensitivity — fine-tune the detection threshold • Min Interval Between Hits — prevent double-counting on loud shots • Bounce Ignore Time — filter out ground bounces after each hit • Bounce Amplitude Ratio — distinguish bounces from real hits • Phone Placement — choose Near Player or Near Wall • Distant Hit Ratio — sensitivity multiplier for far sound sources • Precision — control audio polling interval • Rally Timeout — set silence period before ending a rally - Customizable Voice Announcements Toggle individual end-of-rally announcements on or off: Serve Speed, Shot Counter, Fastest Shot, Average Shot Speed, and Rally Duration. Choose the TTS voice and adjust the speech rate to your preference. --- PRIVACY FIRST TennisWall works entirely on your device. No account required. No personal data collected. No audio recordings saved. No analytics, no ads, no cloud uploads. All training data and settings stay in local storage under your control. --- PERFECT FOR • Solo players training against a tennis wall or backboard • Coaches tracking player serve speed and consistency • Anyone who wants measurable, data-driven tennis improvement without buying radar guns or wearables --- GET STARTED IN 30 SECONDS 1.
