Improve your game and analyze your performance with Badminton Advisor, the ultimate companion app for badminton players! 🏸

Never lose track of the score mid-set again. A phone app plus a Wear OS watch app: keep score from your wrist during the action, then analyze your performance once you're off the court.

⌚ ON YOUR WATCH (WEAR OS): THE REFEREE ON YOUR WRIST
• Intuitive Score Tracking: tap to add a point for yourself or your opponent — two large buttons filling the screen, each gesture with its own haptic feedback.
• Service Fault Tracking: double tap instead of tapping to record a point that ended on a service fault. Long press to undo. No menus, no fiddling between rallies.
• Real-Time Heart Rate: the app reads your watch's built-in heart-rate sensor live during the match and shows your BPM on screen, so you can gauge your intensity rally by rally.
• BWF 15 or 21 Point Rally Scoring: choose the format in the settings and it syncs to your watch. Sets to the new 15 or the traditional 21.
• Complete Match Management: set tracking, automatic mid-set technical pause detection, and match completion validation.
• Always-On Display: the screen stays lit during play — check the score without lifting your wrist.

📱 ON YOUR PHONE: YOUR ANALYSIS AND HISTORY
Your data syncs to your phone automatically when the match ends:
• Detailed History: all your past matches, scores per set, and match durations.
• Match Statistics: far more than a scoreline. Per match and per set -- points won, serve versus receive win rate, where your service faults happened, longest runs won and lost, longest serve retention, biggest lead and deficit, and rally tempo.
• Effort Analysis: heart rate minimum, average and maximum for the match and per set, including where your heart rate entered and left each set, plus the rest you took between sets.
• Charts: score progression and heart rate plotted for every set, so you can see the moment a set turned.

❤️ HOW HEART RATE IS USED
Badminton Advisor reads your heart rate from the optical sensor built into your Wear OS watch — no chest strap, no extra app.

Measurement starts when you start a match and stops when it ends. Each reading is attached to the rally being played — that is what makes the effort analysis possible: which rallies cost you the most, whether your errors pile up when your heart rate peaks, and how well you recover between sets.

🤖 THE "SMART ADVISOR" (AI PROMPT GENERATOR)
The app assembles your match into a detailed prompt: every statistic pre-computed, the full rally log, and explicit instructions about what the data can and cannot support, so you don't get invented advice.

Export it in one tap to your favorite AI app (ChatGPT, Gemini, Claude, and others) for a verdict on how the match was won or lost, whether your service faults cluster under pressure, what your heart rate says about your conditioning, and three things to work on next session.

🔒 PRIVACY: YOUR DATA STAYS ON YOUR DEVICES
Your sports data belongs to you.
• No account required, no sign-up.
• Badminton Advisor has no servers. Your match history and heart-rate data are stored only on your watch and your phone, and are never uploaded.
• No ad tracking, no analytics, nothing sold to third parties.
• Your heart-rate data stays in Badminton Advisor: it is not sent to Health Connect, Google Fit or any other fitness app, and nothing is read from them.
• The AI analysis is optional and never automatic. The app shows you exactly what health data the text contains and asks you to confirm before passing it to the app you choose in the Android share menu. If you never use it, your heart-rate data never leaves your devices.

📋 REQUIREMENTS
• A Wear OS 3.0 or newer smartwatch with a built-in heart-rate sensor, paired to your phone
• Android 7.0 or newer on the phone
• The watch and phone apps install together from this single listing
