About this app
Razorline is a GPS lap timer, driving dashboard and OBD2 telemetry tool — for track days and closed circuits, and for your everyday car too. Record laps and sectors, follow your live delta, keep an eye on engine data and on the state of your tires and components. Use your phone GPS without an OBD adapter, or try the built-in simulator before connecting your vehicle.
EVERY DAY
• Customizable live dashboard with speed (GPS speedometer), RPM, route, G-force and driving data.
• Record Tours and revisit their routes, telemetry and speed heatmaps.
• Personal speed traps with separate records for each vehicle.
• Session history organized by 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.
• Use phone GPS or a compatible external Bluetooth GPS receiver on Android.
CIRCUIT CATALOG
More than 50 famous circuits, ready to use and available offline: Monza, Imola, Spa-Francorchamps, Silverstone, Suzuka, Nürburgring, Le Mans and many more, with start lines and sectors.
OPTIONAL OBD2 TELEMETRY
Connect a compatible ELM327 adapter via Bluetooth Classic, BLE or Wi-Fi. See supported values such as RPM, throttle, coolant and intake temperature, air flow, fuel level and vehicle speed. As an OBD2 scanner, read and clear diagnostic trouble codes (DTC) and turn off the check engine light, including newer cars (2020+) that need an extended dialogue with the ECU. 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 the last service, with maintenance reminders. 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, the circuit catalog, 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. Manage or cancel your subscription in Google Play.
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 timing, sectors, challenges and performance tests only on closed circuits or private areas closed to traffic; on the road, use diagnostics, maps and the trip log. 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.
