Track Gear - Lap Timer

Push your limits, starting with precise data!

Track Gear (T-Gear) is a professional-grade GPS lap timer and telemetry data analysis tool designed for track enthusiasts, canyon runners, and performance car owners. Whether you are chasing your fastest lap on a closed circuit or logging sector times on classic mountain roads, T-Gear is your ultimate virtual racing engineer.

🏁 [Core Features]

• 🗣️ Live TTS Voice Feedback
Keep your eyes on the apex! T-Gear features a smart voice broadcast system that instantly reads out your Delta Time (e.g., "0.5 seconds faster") when passing a checkpoint. Adjust your driving rhythm by ear, without ever looking down at your screen!

• ♾️ Custom Tracks & Multi-Lap Mode
Plot unlimited checkpoints directly on the map. T-Gear supports a "Closed Circuit Multi-Lap Mode" that automatically triggers the next lap after crossing the finish line and logs all your individual lap times accurately.

• ⏱️ Sector Timing for Canyon Runs
For non-closed mountain roads, T-Gear utilizes Google Maps API to perfectly snap to the road trajectory, precisely calculating your sector times to find your fastest segments.

📊 [Pro-Level Telemetry Analysis]

• G-G Diagram (Friction Circle): Visualizes your longitudinal (acceleration/braking) and lateral (cornering) G-forces using your phone's accelerometer to review your tire grip limits.
• Speed & Altitude Charts: Analyze exactly where you lifted off the throttle early or where your mid-corner speed can be improved.
• Vehicle Garage: Save your car's specs and drivetrain layouts (e.g., AWD) and link them to your track records.
