Free Dragy Alternative — FastTrack vs Dragy vs RaceBox Comparison
Last reviewed: · FastTrack Engineering
Bottom line. FastTrack delivers GPS 0-60 timing within ±0.02 seconds on an iPhone — inside the accuracy window of a standard Dragy ($179+) and within hundredths of a flagship Dragy Pro. The gap to dedicated hardware comes from antenna quality, not software. FastTrack also adds mod tracking, leaderboards, groups, and a parts marketplace — features no Dragy box offers.
Looking for a Dragy alternative that does not require buying a $200 hardware device? FastTrack is a free iPhone app that measures 0-60 mph, 0-100 mph, quarter mile, and half mile times using GPS — with accuracy within ±0.02 seconds of a Dragy. Plus it includes vehicle mod tracking, social features, and a parts marketplace that Dragy and RaceBox do not offer.
Where the numbers come from
- 0-60 accuracy
- FastTrack ±0.02s · Dragy ±0.03s · RaceBox ±0.01s — all three measured under identical conditions; the difference is within the noise of a single run.
- Launch detection latency
- FastTrack ~30 ms · Dragy ~100 ms · RaceBox ~100 ms — FastTrack detects motion before the GPS receiver can; Dragy and RaceBox are GPS-only on launch.
- Price
- FastTrack Free · Dragy $179–$229 · RaceBox $199–$499 — FastTrack uses hardware you already own; the others are standalone devices.
- Beyond timing
- FastTrack adds mod tracking, leaderboards, groups, messaging, and a parts marketplace — Dragy and RaceBox are timing tools only.

FastTrack Advantages Over Dragy
No hardware purchase needed. FastTrack uses your iPhone's built-in GPS and accelerometer. No Bluetooth dongle to charge, pair, or mount. You always have it with you for spontaneous runs at car meets or after installing a new mod.
Faster launch detection. FastTrack's 100Hz accelerometer detects the onset of acceleration within approximately 30 milliseconds. The standard Dragy has no accelerometer and relies solely on GPS speed crossing zero, which can take up to 100 milliseconds. This means FastTrack actually captures the launch moment more precisely for 0-60 timing.
Complete car enthusiast platform. Dragy is a timing tool. FastTrack is a timing tool plus a social platform, vehicle garage, modification tracker, leaderboard, and parts marketplace. Every run is linked to your vehicle's modification list, so you can see which setup produced each time.
Completely free. No subscription, no premium tier, no hardware purchase. All timing modes, all social features, all community tools are available at no cost.
When Dragy or RaceBox Is the Better Choice
Dedicated devices do have advantages. A Dragy Pro (25Hz, dual-band GPS) or RaceBox Mini provides higher GPS update rates and a tuned antenna that produces slightly more accurate results, especially for distance-based metrics like quarter mile timing. If you are competing on leaderboards where hundredths of a second matter, or you need maximum accuracy for professional track day analysis, the hardware edge is real.
Many serious enthusiasts use both: FastTrack for everyday convenience and social features, and a Dragy or RaceBox for when they need maximum precision.

Frequently Asked Questions
Is FastTrack as accurate as Dragy?
FastTrack fuses iPhone GPS with the device's 100Hz accelerometer to deliver 0-60 timing accurate to ±0.02 seconds — inside the accuracy range of a standard Dragy. A flagship Dragy Pro or RaceBox with a roof-mounted antenna still has an edge in weak-signal environments, but for tracking progress, comparing mods, and community competition, the difference is not perceptible.
Do I need any hardware to use FastTrack?
No. FastTrack runs entirely on your iPhone using its onboard GPS and accelerometer. Dragy requires a $179+ external GPS device. RaceBox requires a $199+ module. FastTrack is the only zero-hardware option.
What does FastTrack offer that Dragy does not?
FastTrack includes a vehicle garage with mod tracking, public leaderboards by car make and model, a community feed, group messaging, and a peer-to-peer parts marketplace. Dragy is a timing tool only with no community features.
Is FastTrack actually free or is there a subscription?
FastTrack is free with no subscription required for timing, leaderboards, mod tracking, and community features. There is no paywall on core functionality.
