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.

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.
