StopWatch For Multiple Cars

A purpose-built stopwatch for grassroots motorsport. Time several cars at once on a single iPhone — no more juggling four different stopwatch apps with sticky tape labels. Designed for autocross corner workers, track day instructors, drift judges, and anyone running a small event without a real timing rig.

What it does

• Multi-car timing on one screen. Each car gets its own card with its own start/stop/lap controls.
• Per-car lap history. Best lap, last lap, and a running list — all visible at a glance.
• Saved sessions. Every event you time is saved. Pull up last weekend's autocross results without re-keying anything.
• Dark interface. Easy to read in bright sun, easy on the eyes at night.
• No accounts, no ads, no tracking. Open it, time the cars, done.

Who it's for

Solo drivers, autocross corner workers, drift event judges, kart racing parents, track day coaches, and anyone who needs to time multiple vehicles at once without buying a real timing system.
