Description
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.

What's new (v1.1.1)
New Features:
VDE (Vehicle & Driver Evaluation Protocol) Analysis (Beta): Leverages a physics-based vehicle dynamics model to independently evaluate driver skill and vehicle performance, providing precise corner-by-corner suggestions for lap time improvement. Currently supported at Shanghai Tianma Circuit, Zhejiang International Circuit, Ningbo International Circuit, Guangdong International Circuit, and Chengdu Tianfu International Circuit.
Nearby Tracks: Introduced a "Supported Tracks" feature to quickly discover racing circuits around your current location.
Dual-Lap Friction Circle: The dynamic G-force friction circle is now available in dual-lap comparison mode! It features two distinct colored dots on the same screen, allowing you to instantly visualize the differences in cornering limits and driving dynamics between two laps.
Google Maps Integration: Added Google Maps as an alternative satellite map provider for users outside of Mainland China.
New Track Support: Added the Macau Coloane Karting track.
Improvements & Fixes:
Data Analysis & Comparison Fixes: Fixed an issue where the comparison lap's vehicle chevron heading would display incorrectly when rotating the map.
UI & General Optimizations: Refined the Delta Plot header layout and updated the built-in sample session data for a better trial experience.
