The paddock notebook
The paddock notebook
that knows the track.
A track-day notebook with the circuit built in:
- Log sessions, pressures, and setup against real maps of 38 circuits
- Numbered corners, your own reference points, and a computed reference line to study before you ride
- Offline-first, no account, one app on iPhone and Mac

Track Guides
Corner-by-corner guides, computed.
Entry, minimum and exit speeds, brake points, radii and elevation for every corner of 19 US circuits — produced by running a motorcycle physics simulation over each track's real geometry, then written up corner by corner.
Line Lab
The line, solved live.
An in-browser lap simulator on the same real circuit geometry: pick a circuit, set bike class, mass, power and grip, and watch the racing line's speed profile and lap time re-solve as you ride the sliders. Free to try — no install, no account.
