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: • High-Precision GPS Data: Supports external GPS receivers with up to a 25Hz update rate, completely eliminating the lag of built-in smartphone GPS. • Universal Video Auto-Sync (Patent Pending): A pioneering dynamic timestamp QR code solution that breaks device barriers, supporting ANY external camera or smartphone for video recording. Simply record the on-screen QR code before driving; upon import, the app visually scans it to achieve millisecond-perfect alignment between your video and telemetry data, completely eliminating tedious manual timeline adjustments. • Bluetooth OBD Telemetry: Support for connecting external Bluetooth OBD modules.

Without needing any account registration, your pit crew or friends can use a web browser to send real-time commands (like "Box") directly to your live dashboard while you are driving. • 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. • 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 or day's best lap, letting you instantly know your current pace. • Session Analysis & Dual-Lap Comparison: A dedicated landscape analysis workspace seamlessly integrating map trajectories, telemetry graphs, and onboard videos. Features highly synchronized dual-video and data playback to compare two laps side-by-side, visually identifying fast and slow sectors to find exactly where to push harder. • Video Export with Data Overlay: Export your track highlight videos with professional telemetry HUDs with a single tap. Freely configure the overlay elements (speed, G-force friction circle, OBD data, etc.) to create highly personalized videos ready for easy sharing. • 1,000 Built-in Tracks: Pre-loaded with nearly 1,000 touring car and karting tracks worldwide.
