Tire sets

Every set gets a name. Laps and heat cycles add up by themselves each time a run is logged with that set on the car. Durometer goes hard, the sheet says when a set is done.

Limits

When the sheet calls a set done. Change them to what your tire and your tracks tell you.

Lap timer

Stand at the fence. One tap every time the car crosses the line. Big button, greasy thumb.

What won

Gear and RPM

What each gear would do

Same speed at the stand, different gear. Stagger changes count too: a bigger right rear is like a taller gear.

The day

Forecast loads when the phone has signal.

Next session

Set the time and the countdown runs. The phone buzzes at 20 and 10 minutes if this page is open.
