Everything FastTrack does, in one app.
FastTrack is the complete toolkit for car enthusiasts. Precision GPS timing is just the start, it brings together seven systems, measuring, building, and community, in a single free app for iPhone and Android, with no extra hardware.
Performance Timing
Time standing 0-60, 0-100, quarter-mile and half-mile with automatic launch detection. FastTrack fuses GPS Doppler velocity with your phone's 100Hz accelerometer to resolve times to about ±0.02s, validated side-by-side against a dedicated Dragy GPS meter to within 0.01s on the same run. A rolling mode times roll-on pulls such as 60-130 mph for high-power cars where a standing launch is traction-limited.
Vehicle Garage & Mod Tracking
Log every modification across 10 categories with brand, product and notes, then compare before-and-after acceleration runs to measure exactly what each upgrade is worth. Manage unlimited vehicles, each with its own photos, build notes and shareable profile.
Community & Feed
Post GPS-verified runs and builds, follow other drivers, and browse a feed of real member vehicles and times, backed by data, not unverifiable claims.
Leaderboards & Rankings
Every verified run feeds global leaderboards ranked by class and bracket. Filter by vehicle, see performance rankings by make and model, and compare two cars head-to-head.
Groups & Messaging
Start or join public and private groups for your car, club or region, and keep talking with direct messages, sharing runs, vehicles and listings as rich cards right in the chat.
Races & Car Meets
Join live and upcoming community races decided on verified numbers, and find car meets and track days near you.
Parts Marketplace
Buy and sell OEM and aftermarket parts with Stripe-secured checkout and buyer protection, at the lowest fees in the category, a 3% buyer fee and 6.5% seller fee, versus 13.25% on eBay and 10% on Facebook.

Frequently Asked Questions
What can FastTrack actually do?
FastTrack is one app that combines GPS 0-60 and quarter-mile timing, a vehicle garage with mod tracking, a social feed, groups and messaging, global leaderboards, community races and car meets, and a peer-to-peer parts marketplace. Everything is included and free.
What is the best 0-60 app for iPhone and Android?
FastTrack times 0-60, 0-100, quarter-mile and half-mile to about 0.02 seconds using your phone GPS and 100Hz accelerometer, with no external box to buy. It is free on both iPhone and Android, and every run is saved to your garage and can feed the global leaderboards.
Is FastTrack a good Dragy alternative?
Yes. In side-by-side testing FastTrack matched a Dragy GPS meter to within 0.01 seconds on the same run, but it runs on the phone you already own instead of a separate GPS box, and adds a garage, leaderboards, community and a parts marketplace that a standalone meter does not have.
Is FastTrack a performance app or a car community app?
Both. FastTrack is a precision performance app for GPS timing and mod tracking, and a full car community app with a social feed, groups, direct messages, community races and local car meets. You get the data tools and the enthusiast community in one download.
Is FastTrack free?
Yes. Timing, the garage, the community feed, groups, leaderboards, and races are all free on iPhone and Android. There is no subscription and no hardware to buy.
How accurate is the timing?
FastTrack resolves 0-60 mph to about 0.02 seconds by fusing GPS Doppler velocity with the phone 100Hz accelerometer. It has been validated side-by-side against a Dragy GPS meter to within 0.01s on the same run.
Do I need any extra hardware?
No. FastTrack runs entirely on the phone built-in GPS and accelerometer. A phone mount is recommended for safety, but no OBD adapter, external GPS box, or Bluetooth accessory is required.
