Read full description
👐 ClapTimer - The Hands-Free Round Timer for Combat Sports & CrossFit Tired of touching your phone with sweaty gloves? ClapTimer uses AI-powered clap detection to control your round timer completely hands-free. Just clap once to start or pause, clap twice to reset. It's that simple. 🥊 PERFECT FOR: • Boxing training • Brazilian Jiu-Jitsu (BJJ) drilling • Muay Thai rounds • CrossFit intervals & EMOM workouts • Wrestling practice • MMA conditioning • Tabata & HIIT training • Any sport that uses round timers ⏱️ HOW IT WORKS: • 👐 1 Clap → Start or Pause the timer • 👐👐 2 Claps → Reset the current round • No need to touch your phone during training! 🎯 KEY FEATURES: ✅ AI-Powered Clap Detection Uses Google's YAMNet machine learning model running entirely on your device to accurately distinguish claps from speech, music, and background noise. No internet required for detection. ✅ Fully Configurable Timer • Set round length (minutes or seconds) • Set rest duration • Set total number of rounds • Configure warning countdown (with sound alert before round/rest ends) • Tap any value to type it directly ✅ Audio Feedback • Boxing bell sound at round start and end • Countdown beep warning before time runs out • Voice announcements: "Round started", "Round paused", "Round over. Rest." • Sound on/off toggle for silent training • Voice language matches your device language ✅ Works in Background • Keeps listening for claps with screen off • Foreground service with notification • Stop button in notification • Auto-stops after 60 minutes of inactivity to save battery ✅ Adjustable Sensitivity • Slider to fine-tune clap detection sensitivity • Default set to 90% (highly reactive) • Lower it if you get false positives in noisy environments ✅ Clean, Dark UI • Large, readable timer display • Auto-sizing text fits any screen • Round/Rest phase clearly indicated with colors • Works in any screen orientation 🔒 PRIVACY FIRST: • NO audio is ever recorded, stored, or sent anywhere • All audio processing happens locally on your device • No account needed, no tracking, no data collection • Microphone only active when the listening service is running 💡 TIPS FOR BEST RESULTS: • Clap loudly and sharply for best detection • If playing music, use headphones or a Bluetooth speaker (device speakers can interfere with the microphone) • Adjust sensitivity slider if needed for your environment • The app works best in environments without constant loud clapping/banging sounds 🌍 AVAILABLE IN 15 LANGUAGES: English, Portuguese (Brazil), Spanish, French, German, Italian, Russian, Japanese, Korean, Simplified Chinese, Traditional Chinese, Arabic, Hindi, Turkish, Indonesian 📱 REQUIREMENTS: • Android 10 or higher • Microphone permission (for clap detection only) Train harder, train smarter — let ClapTimer handle the clock while you focus on your workout! 🥊🥋💪
