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.

New Features:
1. Built-in Phone Camera Recording: You can now use your phone's native camera to record your track sessions directly within the app, seamlessly syncing onboard video with your telemetry data without needing an external action camera.
2. Transparent Overlay Export: Designed for advanced video creators, you can now export your telemetry HUD with a completely transparent background. This is perfect for custom compositing in third-party video editing software like Premiere Pro or Final Cut Pro.
3. New Track Support: Added Beijing Wenyuhe Karting, Hangzhou Ruisu Karting, and Nanjing Liwan (Jiangning) Karting tracks.
Improvements & Fixes:
1. Dashboard Rotation Lock: The live dashboard orientation is now automatically locked during active recording sessions. This prevents unintended screen flips caused by heavy G-forces, sharp cornering, or track bumps.
