The technology

Not a lap timer.
A race engineer.

01
Ghost Protocol

The Perfect Lap — Extracted from Sim

Professional-grade lap data extracted from Assetto Corsa for every car and track combination. Sim Cartesian coordinates normalised to real-world GPS — corner by corner, brake zone by brake zone.

This is the reference line your AI race engineer targets on every lap.

Sensor Fusion

25Hz GNSS + 100Hz IMU — Fused

Your iPhone and a Bluetooth GNSS puck are fused via Extended Kalman Filter. Position is predicted 50 milliseconds ahead to neutralise Bluetooth latency.

The cue arrives before the corner — not during it.

Physics Engine

Braking Physics. Live. On Device.

On-device physics calculates the exact brake point for your speed, tyre friction coefficient, and real-time surface conditions via the Met Office API.

Dry, damp, wet. The engine adapts every lap, every session.

“I built RaceLineApp.ai because I live this problem. I’m a regular track day driver, I watch YouTube videos and run sim laps before I go out. I analyse my performance but nothing improves it more than having a professional next to me. The technology is designed for this from the inside out.”
