About this app
RaceLineCalc calculates a racing line from your own track image, map, plan, sketch, or satellite screenshot.
Use track analysis to study apex placement, cornering, braking points, speed, and lap time.
Create a track project:
• Import an image and calibrate it with a known real-world distance.
• Trace the left and right track boundaries and place the start/finish reference.
• Choose a point-based, car-based, or motorcycle-based model and a vehicle preset.
• Run the calculation on your device.
Review the result:
• Calculated racing line and lap time.
• Speed, longitudinal acceleration, lateral acceleration, and braking points.
• Calculation stations, source boundaries, and generated track geometry.
• Run history and comparison of compatible results on the same track.
The point-based model quickly calculates a stable racing line. Car and motorcycle models add vehicle mass, power, grip, braking, dimensions, steering, and lean-related parameters. Presets cover karting, road cars, track cars, and motorcycles, while advanced controls allow deeper experiments.
RaceLineCalc is local-first: the calculation runs on the device, and the core project flow does not require an account or upload your track project to a RaceLineCalc server.
Model scope:
RaceLineCalc calculates on a calibrated flat 2D track model. Elevation, banking, jumps, ruts, changing grip, weather, traffic, live surface conditions, and other real-world factors remain outside the current model. Always combine the calculation with real track knowledge and safe driving or riding practices.
