PitLaunch turns your iPhone into a pocket performance timer. Line up, launch, and get your real 0–60 — timed to the hundredth of a second. PitLaunch fuses GPS speed with your iPhone's motion sensors to time your run the instant you launch. No extra hardware, no wires — just mount your phone and go. PitLaunch is free to download. Timing runs and all the features below require PitLaunch Pro, an auto-renewing subscription (monthly or annual) purchased in the app — the price is always shown before you subscribe, in your local currency. WHAT YOU CAN TIME (requires PitLaunch Pro) • 0–60 mph (or 0–100 km/h) • The quarter mile — with ⅛-mile split, trap speed, and 0–100 mph • Roll-on pulls like 50–70 mph • Peak G, plus a live G-meter that tracks g-forces in every direction BUILT FOR ENTHUSIASTS • Standstill or 1-foot rollout — the same conventions as the drag strip • Automatic launch detection: arm it, drive, and PitLaunch captures the whole sheet for you • A big, glanceable readout designed to be mounted and read at speed • Works in mph or km/h SHARE YOUR RUNS Every run becomes a clean, branded card — your time, your car, and the real speed trace — sized for Instagram and ready to post in a single tap.
