RaceLineCalc: Track Analyzer

Description

RaceLineCalc is also available as a mobile app on Google Play and the App Store.



RaceLineCalc calculates a racing line from your own track image, map, plan, sketch, or satellite screenshot. Use the optimized racing line to improve your lap times.



Use track analysis to study apex placement, cornering, braking points, speed, and lap time.

A practical tool for motorsport, racing, and sim racing.

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.

Five physics models

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.

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.

Compare saved runs

• Run history and comparison of compatible results on the same track.

Local-first workflow

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 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.
