Whether you've tuned an F80 M3, want to track gains on a G80, or just settle a debate about your 335i, a GPS meter gives you repeatable, satellite-timed numbers. It's the honest way to measure what a tune actually did — pairs neatly with our tuning guides.
What Is Dragy?
A GPS timing box that lives on your dash.
Dragy is a performance-timing gadget from Dragy Motorsports that mounts on your dashboard and uses GPS satellite data to track the car, sending the numbers to your phone over Bluetooth via the Dragy app. It works on any car regardless of make, and can be set up for a specific track, distance or speed bracket. The app gives real-time stats and post-drive analysis — using your phone's cameras for on-screen overlays of lap times and conditions, and storing graphs, run comparisons and even a global leaderboard.
Key Features
What you actually get.
- Preset & custom modes: ready-made speed-bracket and distance presets, plus custom setups to dial in exactly what you want to measure.
- Claimed high accuracy: Dragy states the GPS timing is accurate to within a hundredth of a second, drawing on multiple satellite systems.
- Stable Bluetooth: a solid phone connection, with the app on both Android and iOS.
- Quick setup: only a few steps from unboxing to your first run.
- Long battery life: newer models such as the DRG70 V2 are rated up to around 25 hours, so longer sessions aren't a problem.

How to Set It Up
A few minutes from box to first run.
Mount It on the Dash
Use the supplied magnets and adhesive to fix the mount to the dashboard, then drop the box on. The centre of the dash is ideal — the device works best with its light facing the sky and a clear view up. The magnet mount makes it easy to pop on and off.
Install & Pair the App
Download the Dragy app, then pair your phone to the box over Bluetooth. Select your vehicle and choose the track layout and specs you want to measure.
Check the Status Light
A blue light means it's fully online with satellites acquired and ready. A red light means the battery is running low — charge it up.
Reset If Needed
If it misbehaves: disconnect and wait ~30 seconds until the light goes off, briefly connect the charge cable then unplug, and wait about a minute — that restores factory settings. Check the manual before first setup.
How the App Works
Raw GPS data turned into insight.
The app is fed raw data from the box, sourced from multiple GPS satellites. Your phone's front and back cameras can record the drive with real-time overlays for track, lap times, conditions and speed. Beyond the presets, you can build custom measurements (tap the plus icon, then Custom Mode). After a run, you get speed, acceleration and elevation graphs, racing lines and lap breakdowns, the ability to compare against previous runs, and a leaderboard to stack up against other users. You can scroll through the whole drive to see exactly where you were accelerating or braking.
Pros & Cons
The honest balance.
- Compact — slips into the glovebox when not in use.
- Lots of useful data, both live and in post-drive analysis.
- Upgraded models last up to ~25 hours on a charge.
- Preset and customisable speed/distance modes.
- Uses multiple satellite systems for accurate data.
- Status LEDs can be a little distracting at night.
- Requires a phone — some rivals don't.
- Ads appear on the app's loading screens.
- Support is via a feedback form, no direct line.
- Sparse printed documentation in the box.
Dragy vs Racebox
The closest rivalry for most drivers.
| Dragy | Racebox |
|---|---|
| Needs the app/phone to operate | Standalone — no phone required |
| Interactive, scrollable post-run analysis | Predictive timing from past sessions |
| Roughly half the price of the pricier rigs | Optional external GPS antenna |
| Light and very portable | Stores up to ~400 sessions |
| Up to ~25 hours battery | Up to ~8 hours battery |
For most BMW owners the choice comes down to phone-or-not: Dragy's app gives richer, scrollable analysis and far longer battery for less money, while Racebox wins if you want a self-contained device with on-board storage and no phone trackside.
FAQ
How accurate is Dragy?
Dragy says it's accurate to within a hundredth of a second, using several global navigation satellite systems to track the car. In practice it's the widely trusted enthusiast benchmark for GPS-based timing.
How do I turn Dragy off?
Disconnect the box and wait for the light to switch off fully — around 30 seconds.
How do I get a countdown / lap timing?
Lap times and countdowns are in the Dragy Lap app, which uses your phone's cameras and real-time prediction to monitor your current lap against previous ones.
Is the Dragy app free?
Yes — the app is free on both Android and iOS.
Does Dragy measure 60ft?
Yes, but only within the quarter-mile timer mode; your 60ft figure shows in the post-run analysis.
The Bottom Line
For measuring what your BMW really does — and what a mod really changed — the Dragy GPS meter is the easy recommendation: accurate, feature-rich, long battery and accessibly priced. Prefer no phone, go Racebox; want an open-app box, Racebox Mini; want a standalone pro screen, Racelogic. Whichever you pick, run it on a closed course and pair it with our tuning and diagnostics guides to track real gains.
