What we do

A road you have never driven,
read out loud.

A road you know well feels different. You know where it tightens, where it opens, where the hairpin waits behind the crest. Nothing surprises you.

Hairpin gives you that on a road you have never seen.

Choose a start and a finish. Hairpin reads the geometry of the road between them — every radius, every change of direction — and turns it into pace notes: the same calls a rally co‑driver reads to a driver. Each corner is graded, from a hairpin to a wide open six, and announced with the distance to it, spoken before you arrive.

The notes follow the road and the way you drive: single lane or double, touring pace or something sharper. Once a route is generated it lives on your phone, so it keeps working where the signal does not — which is usually exactly where the good roads are.

How it works

Three steps, then you drive.

  1. 01

    Pick two points

    Search a place, drop a pin on the map, or type coordinates. Hairpin finds the roads that connect them and lets you choose which one you want.

  2. 02

    It reads the road

    Every curve is measured from open mapping data: radius, length, how it enters and how it leaves. That becomes a graded call, the way a co‑driver would write it.

  3. 03

    It calls the corners

    On the move, each corner is shown and spoken ahead of time, with the distance counting down. Set the pace, the voice and how far ahead you want to hear it.

Try it

Take it up a pass.

Hairpin is in early testing. It already generates routes, shows the corners and reads them out — and we are still tuning it against real driving.
