Session setup on iPhone: per-corner tire pressures, temperatures, and damper clicks
01

Cars & setups

Dampers from non-adjustable to 4-way. Per-corner tire pressures, sizes, and tread temperatures. Ride height, camber, toe, springs, and caster need Pro.

02

Session logging

One session per outing: circuit, car, dry / damp / wet, ambient temperature, comments. Each one stores the setup you ran.

03

Lap timing, three ways

Stopwatch. GPS auto-timing off a virtual start/finish line. Manual entry. Every lap stores the setup and conditions it was set on.

04

Session comparison

Overlay sessions on one graph. Two sessions show the best-lap difference. Pro adds the extra setup-delta rows.

05

Schematic & heat map

Top-down car drawing with setup callouts. Log pyrometer readings for a tread heat map. Green means that compound is in its window.

06

No sign-up

Open the app and drive. Data saves from first launch. Add email and password later to use it on other devices.

How it works

STEP 01

Log the car

Enter the car once: dampers, tire pressures, session notes. Geometry and springs need Pro. New sessions copy that setup.

STEP 02

Run the session

Pick the circuit, note the conditions, time laps by GPS, stopwatch, or hand. Everything auto-saves.

STEP 03

Change one thing

Compare sessions, read the delta, keep what worked.
