The Speedy board

Hardware · first batch sold out

Give your runs a dedicated GPS receiver. The Speedy Board pairs with the app over Bluetooth, combining its own GNSS antenna and motion sensor in a compact, USB-C rechargeable case. Your phone stays the screen; the board provides the measurements.

Be ready for the next batch.

The first batch is sold out. Interested in v2? Email us to hear when it becomes available.

Dedicated GNSS

u‑blox MAX‑M10S with its own 25 × 25 mm patch antenna, dedicated to measuring your run.

Launch detection

A dedicated six-axis motion sensor provides acceleration and rotation data to the app.

Lives with the app

Bluetooth LE to your phone, firmware updates through the app, USB‑C charging, and a four-LED gauge: charge level, a sweep while it hunts satellites, solid on fix.

Pocket sized

The v2 design fits a 69.5 × 34 mm PCB into an 80.35 × 40.2 × 17.8 mm case with magnets in the base. Nominal CAD dimensions.

Start with your phone. Add a dedicated sensor.

Use the app on its own, or connect a Speedy Board. Your run history and leaderboard stay in the same app.

Illustrative demo data — 132 mph top speed, 0.79 g peak, GPS ±1.1 mph on 11 satellites, 73 °F at 774 ft with a 2,043 ft density altitude, +1.2% grade. The 1‑ft rollout brings this pass's 0–60 to 3.72 s, and every board keeps splits at each 10 mph or km/h.

Speedy's performance report: 60 ft, 1/8 mile and 1/4 mile cards with trap speeds, the full mph splits table with 1 ft rollout, and the run's ground track drawn between start and finish flags on a dark street map with peak g, top speed and satellite pills.

How a pass gets timed

GPS and the accelerometer, fused

Speed comes from GPS; the launch instant comes from the accelerometer. The report shows GPS accuracy, satellite count and launch confidence, so you can review the conditions behind each result.

Density altitude, computed per run

Temperature and pressure are looked up for where you are, and the report carries elevation, slope and density altitude — the difference between a brag and a baseline.

The whole curve, kept

Every run is saved on your phone with its splits, speed and g traces, and the ground track drawn on a map. Nothing to export, nothing expiring.

Put it on the board

Compare your best runs with other drivers. Each entry includes the car, trap speed and conditions, with times taken directly from the recorded run.

Phone and Speedy Board runs share the same leaderboards, with an icon showing the measurement source.

Your route stays home

Publishing sends the numbers, never the map. The GPS track of your run is stored only on your phone and is stripped from every leaderboard entry before it leaves the device.

Speedy's 60-130 mph leaderboard: three ranked entries by the same car with times, rolling-start badges, density altitude and grade.

A few things to know about the app and the next Speedy Board.

Something else on your mind? Email us →

Do I need a Speedy Board to use the app?

No. Speedy can measure runs using your phone’s GPS and motion sensors. The board is an optional, dedicated measurement source that connects over Bluetooth.

Does Speedy work on iPhone and Android?

Yes. Speedy is available on the App Store and Google Play. Both apps support connecting to a Speedy Board.

Does the board replace my phone?

The board supplies GPS and motion measurements. You still use the Speedy app on your phone to view and manage your runs.

Can I buy the v2 board now?

The first test batch is sold out, and v2 is shown here as a design preview. Email your interest in v2 to hear when the next batch becomes available.

What about pricing, battery life and shipping?

Final v2 pricing, measured battery life, box contents and shipping details are not announced on this page yet. Email us about the next batch for availability and details.

Does publishing a run share my route?

No. Leaderboard entries include your results and vehicle details. Your GPS route stays on your phone and is not included in the published entry.

Your next run starts here.
