About Dexian Timer

Dexian Timer is a professional lap timing and telemetry analysis tool designed exclusively for track day and karting enthusiasts. Fully compatible with the high-performance 25Hz Dexian D1 GPS, RaceChrono DIY protocol devices, and .VBO file imports, it delivers the ultimate smooth experience for lap timing and data review.

KEY FEATURES:
• Auto Lap Timing & Real-Time Delta: Intelligently detects your current track and automatically triggers timing when crossing the start/finish line. During your stint, it displays a precise, position-based real-time delta against your session's best lap, letting you instantly know your current pace on the fly.
• High-Precision GPS Data: Supports external GPS receivers with up to a 25Hz update rate, completely eliminating the lag of built-in smartphone GPS.
• Lap Delta & Trajectory Comparison: Compare two laps side-by-side on screen to visually identify your fast and slow sectors, helping you find exactly where to push harder.
• Action Camera Control & Auto-Sync: Remote control action cameras directly in the app. Video and telemetry data timecodes are automatically and precisely synced, saving you from tedious manual timeline edits (Exclusive to Dexian D1 users).
• 1,000 Built-in Tracks: Pre-loaded with nearly 1,000 touring car and karting tracks worldwide. No manual start/finish line setup required—just arrive and race.
• Perfect Map Alignment in China: Automatically handles map coordinate conversions to completely eliminate the trajectory offset issues common in traditional apps. Your racing line aligns perfectly with the map.

ECOSYSTEM COMPATIBILITY
Supports any Bluetooth GPS receiver based on the RaceChrono BLE DIY protocol. Seamlessly imports and exports industry-standard .VBO files to perfectly integrate with your existing data ecosystem.

IMPORTANT SAFETY DISCLAIMER
Motorsport is inherently dangerous. This application is designed exclusively for use on closed-circuit tracks and professional racing facilities. DO NOT use this app on public roads. The data is for reference only. Always prioritize safe driving.
