LIVE GNSS TELEMETRY

Measure your launch to GPS accuracy.

MotionStint turns a GNSS performance box — Dragy, RaceBox or any BLE GPS, or even your phone's own GPS — into a drag-strip-accurate timer: true 0–100 km/h, 0–60 mph, 1/4-mile and braking, captured live at 25 Hz. It runs in your browser, works offline at the track, and syncs when you're back online.

Drift-proof timing

True 25 Hz GNSS fixes mean a 0–100 that doesn't wander. The same launch, measured the same way, every run.

Fair classes

Ranked by power-to-weight × drivetrain, so a 120 hp hatch never gets buried under a 700 hp AWD hypercar.

One engine, any box

Dragy, RaceBox or a generic NMEA GNSS — auto-detected and measured the same way, so results stay comparable.

Works offline, syncs later

Runs save on your device the instant they finish — even with zero signal at the track — then upload automatically when you're back online.

EVERY COMMON METRIC

What it measures

Every run captures the full acceleration ladder in both units — all the way to 300 km/h — plus rolling pulls, distance, trap speed, braking and g-force. Rank the board on whichever one matters to you.

Acceleration — km/h

0–50 · 0–100 · 0–150 · 0–200 · 0–250 · 0–300

Acceleration — mph

0–30 · 0–60 · 0–100 · 0–150 · 0–180

Rolling / in-gear

100–200 & 200–300 km/h · 60–130 & 100–150 mph

Distance & trap

BRING YOUR OWN BOX

Supported GNSS devices

MotionStint auto-detects your performance box at connect and routes it through one shared metrics engine, so any supported device produces comparable results. The leaderboard tags each run by device tier.

Dragy DRG70

Verified hardware

The flagship 25 Hz GNSS box. Full speed, distance, rolling and braking metrics with derived g-force. Runs carry the Verified-hardware badge on the leaderboard.

0–300 km/h · 0–180 mph · ¼-mile + trap · braking · g-force

RaceBox Mini / Mini S / Micro

Community hardware

Auto-detected over Bluetooth — nothing to configure. RaceBox's 25 Hz stream feeds the exact same metrics engine and competes on the board as Community hardware.

0–300 km/h · 0–180 mph · ¼-mile + trap · braking · g-force

Any NMEA-0183 BLE GPS

Unverified

Generic Bluetooth GNSS receivers that speak NMEA (RMC / VTG / GGA) work too — speed, distance and timing. Listed as Unverified since accuracy varies by receiver.

Speed & distance metrics (no g-force)

Your phone's GPS — no box

Phone-GPS

No receiver at all? Record straight from your phone's built-in GPS. It's ~1 Hz and less precise, so phone runs sit on their own clearly-labelled leaderboard segment — but it means anyone can start timing with zero hardware.

More than a timer

Record the proof, make it look good, and take it to the community — all from the same browser tab, online or off.

Record runs on video

Film the run on your phone's front or rear camera with live speed, g-force and timing composited right into the footage — export a clip that's ready to post.

Share cards in a tap

Turn any result into a clean, branded image sized for Instagram and stories — export or share it straight from the run.

A leaderboard that talks back

Proud of a run? Submit it to the public board, then like, comment and chat with other drivers — opt-in, your call.

Install it like an app

Add MotionStint to your home screen. It opens and records even with no signal at the track, then syncs your runs the moment you reconnect.

Supported: Chrome, Edge, Android Chrome, iOS (Bluefy)Limited: macOS SafariUnsupported: Firefox

THREE STEPS

How it works
