Tennis Tracker Dual: ANT+ Sync
· v1.2
About
Tennis Tracker Dual is the ultimate tennis scorekeeping and activity tracking app for Garmin watches, whether playing solo or syncing wirelessly in real time with your opponent's watch via ANT+ (no smartphone or internet connection required on court).
GAME MODES & EASY PAIRING:
• Solo Mode:
Playing against someone without a Garmin watch? You can use the app 100% standalone to track your own score, games, sets, and record all your fitness and GPS metrics.
• Dual-Watch Sync Mode:
To pair two watches, simply open the app on both devices while standing close to each other (within 2-3 meters / 6-10 feet) before starting the match. The watches will discover each other and connect automatically via ANT+ with zero setup. Once paired, either player can score points, and both screens update instantly.
KEY FEATURES:
• Direct Watch-to-Watch Synchronization:
Ultra-low latency wireless communication between two Garmin devices without phones, cellular data, or Wi-Fi.
• Smart Reconnection & Offline Buffer:
If players move out of radio range during a point, actions are safely queued locally and automatically reconciled when walking near each other at side switches.
• High-Contrast Split Yin-Yang UI:
Optimized for immediate readability under direct sunlight:
- Right Side (Dark Theme): Score and stats for "YOU".
- Left Side (Light Theme): Score and stats for "OPPONENT".
• Visual Server Indicator:
A crisp tennis ball icon clearly marks whose turn it is to serve in games and tie-breaks.
• Haptic Court-Change Alerts:
Triple-pulse vibration and an on-screen banner notify players on odd games and every 6 points in a tie-break.
• Full GPS Activity Recording:
Records the session as an official Tennis activity to Garmin Connect, including real distance, GPS court heat map, heart rate, calories, and match set breakdown.
CONTROLS (Touch & Physical Buttons):
- Right Tap / UP Button: Add point for YOU.
- Left Tap / DOWN Button: Add point for OPPONENT.
