FastRPerformance timing for iPhone
Time it. Post it. Prove it.
FastR turns your iPhone into a timing box. Measure 0–60, the quarter mile and top speed, keep every run in your garage, and settle the argument with a head-to-head challenge.
Built for car people. From the launch to the leaderboard.
0–60, quarter mile, rally and top speed
Mount your phone, wait for the lights, and launch. FastR records the run from GPS and motion data and gives you the time, the trap speed and the full speed curve.
Every car, every mod, every run
Add your cars with their specs and modifications, post photos, and keep each car's best times on its page. See what the intake actually did.
Head to head, wherever you both are
Challenge a friend to a 0–60, a rally or a top-speed run. You each have a week to submit your best, and the result posts as a side-by-side replay.
Leaderboards and a feed for car people
Rank against everyone running the same distance, follow drivers and cars you like, and see when someone posts a car like yours.
Tracks and closed roads only
Never time a run on a public road, and never use the app while you're driving. Set it up when you're stopped, then let the lights do the rest.
