Razorline: GPS OBD & Lap Timer

Razorline combines a GPS lap timer, driving dashboard and OBD2 telemetry for track days and closed circuits. Record laps and sectors, follow your live delta and review your driving data. Use your phone GPS without an OBD adapter, or try the built-in simulator before connecting your vehicle.

LAP TIMING AND GPS • Draw, record or import a route and set start, finish and sector lines. • View current lap, best lap, theoretical best and live sector times. • Record Tours and revisit their routes, telemetry and speed heatmaps. • Use your iPhone GPS. Keep the app and screen active while recording.

OPTIONAL OBD2 TELEMETRY Connect a compatible ELM327 adapter via BLE or Wi-Fi. See supported values such as RPM, throttle, coolant temperature and vehicle speed, and read diagnostic trouble codes. Available data depends on your vehicle and adapter; not every car supports every sensor.

DASHBOARD, REPLAY AND CHALLENGES Follow speed, RPM, G-force, lap time and route on the dashboard and HUD. Review sessions with synchronized maps and charts, compare laps and vehicles, or follow reference ghost laps and share Razorline challenge files. The HUD editor, advanced analysis, comparisons and ghosts require Premium.

VEHICLE CARE Keep profiles for cars or motorcycles and track tire mileage, component distance and time since service. Add distance manually when you drive without the app. Wear percentages are estimates based on your own distance/time limits and recorded use, not measurements of a part’s physical condition. Tires and engine oil maintenance are included for free. Premium unlocks the other maintenance components and custom items. Without Premium those cards show a blurred preview; existing data and automatic counters are preserved.

VIDEO AND EXPORTS Optional phone-camera and compatible GoPro recording are beta features. Import a video and add synchronized telemetry in the editor. Create 9:16 highlights from your own photos or videos. Premium includes camera tools and advanced CSV, GPX, VBO and NMEA exports.

FREE AND PREMIUM The free plan includes lap timing, maps, basic OBD2, tires, engine oil maintenance, up to 2 saved routes, 1 vehicle and 1 saved Tour with review and heatmap. Razorline Premium adds unlimited saved routes, vehicles and Tours, full component maintenance, HUD editing, ghosts and challenges, advanced replay, comparisons, exports and OBD2 tools. Subscription terms are shown before purchase. Restore purchases in the app and manage or cancel your subscription in Apple Account settings.

NO ACCOUNT REQUIRED Available in English, Italian, German, French and Spanish. Recorded sessions stay on your device unless you choose to export or share them.

Configure the app while stationary. Use performance features only on closed circuits or private areas closed to traffic. Follow local laws and never interact with the phone while driving. GPS and OBD readings depend on hardware and conditions and do not replace certified instruments, inspections or professional diagnosis.
