What cold pressures to set
Log a run
Enter what you set (cold) and what you measured after (hot). This is what teaches the app.

Create tyre set
Scan the individual race-control barcode on each tyre. A set is only created after all four different barcodes are saved.
Scan tyre barcode
Hold the barcode flat in the centre, 15–25 cm away, with no glare.
Tyre Set Dashboard
Each set learns from its own logged sessions. “Peak window” and “ageing” are based on your recorded best performance, not an assumed tyre limit.
Compound Intelligence
Clear reports built from your logged tyre sets and runs. Peak-life ranges are observed results, not predictions.
Tracks
Target hot pressure per track — dry, plus optional damp/wet overrides (leave blank to use the dry target). Base = current best cold setup at the reference temp (seeded, sharpens as you log).
Learned adjustments
How each driver / kart class / tyre / weather deviates from the track base — the app's memory. Recent runs count more.

Driver profiles
Set a driver's usual kart and category. Selecting that driver in Recommend fills these fields automatically; you can still change them for a different setup.
Tyre sets
Each saved session adds one heat cycle and its completed laps to the chosen set.

Use the same sync address and private key on each device. Connecting a new device safely downloads an existing backup instead of replacing it.
