Dexian Timer vs Lapforge

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. Read real-time underlying vehicle performance data (such as Engine RPM and Throttle Position) perfectly synced with your GPS telemetry, making your data review and exported videos look like professional motorsport broadcasts. • Innovative Pit2Car Communication: Break the communication barrier between the car and the pit wall! 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. No manual start/finish line setup required—just arrive and race. POWERFUL 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.

Lapforge turns the phone on your dash into a lap timer for HPDE days, club track days and practice sessions. Press GO, drive through your start line, and each lap is timed from GPS. Lapforge places the crossing between two GPS readings instead of waiting for the next one, so a lap is not rounded to the nearest second. Your best and last lap sit in big condensed digits you can read at a glance, and the circuit is drawn as a racing line with your position on it. Built not to lose a session Every GPS point is written to the phone as you drive. If the app is closed mid-session, the laps are there when you open it again. The screen stays awake while timing, and finishing takes a one-second hold, so a bump with a glove does not end your run. Knows the track Lapforge recognizes more than 350 US road courses, ovals and kart tracks from OpenStreetMap outlines and remembers the start line you set at each one. At a track that is not on the list, set your own line as you cross it. Lapforge Pro • Live delta: how far ahead or behind your best lap you are, updated every second • Sector splits: every lap split into three equal-distance sectors, at any track • Lap comparison: a trace of where each lap gained or lost time against your best • Conditions: air temperature, humidity, wind and density altitude from the nearest National Weather Service station, saved with the session • CSV export of every lap and GPS point Free, with no account: lap timing, best and last lap, track detection, saved start lines and your whole lap history. A share card for your best lap is free too. Phone GPS updates about once a second, and accuracy depends on your phone and the sky. The timing screen shows the current GPS accuracy so you know how much to trust a lap. Pro comes two ways: yearly, where the first 7 days cost nothing, or monthly. Both plans bill again by themselves. To stop one before it bills, cancel it under Subscriptions in your iPhone's Settings with at least a day to spare.
