Supported devices

Works with the gear you already own.

Vetkuro records a full session from phone sensors alone, in a car, on a motorcycle or in a kart. Add a Bluetooth GPS receiver, an OBD-II adapter, an action camera or a heart rate strap and the same session picks up more channels. Nothing is rewired, nothing is re-bought.

Every supported device

Four answers per class, in the order you need them: does it work, what data do I get, how do I connect it, and where does it stop. Anything on this list works today, apart from Akso.

Phone sensors

Nothing to buy

Does it work?

Yes, out of the box. A phone alone produces a complete session: laps, sectors, live delta and a line on the map. What it does not produce is detail inside a corner - that is what a receiver is for.

What data do I get?

Position and speed from the phone's own GNSS, plus motion from the accelerometer and gyroscope.

Speed
Position
LateralG
LongitudinalG

How do I connect it?

Nothing to pair. Mount the phone where it can see sky, wait for the fix, hit record.

Where it stops

Phone GNSS typically runs at about 1 Hz, which is 50 m between points at 180 km/h. Vetkuro records every fix the phone gives it, at the highest accuracy the operating system offers; the rate is the phone's, not a setting. Enough for lap and sector times and for the shape of the line, not enough to place a braking point. Throttle and brake are estimated from motion and labelled as estimates.

External GPS

Biggest single upgrade

Does it work?

Yes, over Bluetooth. This is the upgrade that changes the analysis rather than the lap time.

What data do I get?

The same position and speed channels, sampled far more often, plus the receiver's own quality channels.

SatelliteHDOP
FixStatus

How do I connect it?

Power the receiver and pair it in session setup. The setup screen shows whether it is connected before you roll.

Where it stops

Published rates vary by device and firmware; 10 to 25 Hz is the usual range, which is 5.0 to 2.0 m between points at 180 km/h. Bluetooth range is short, so keep the receiver and the phone in the same part of the cabin.

OBD-II

Car dependent

Does it work?

Yes on most cars built from 2008, with one of the adapters listed below. K-Line support is coming soon, and with it older cars.

What data do I get?

What the car reports about itself, instead of what motion implies. RPM and throttle position are near-universal.

RPM
Throttle
EngineLoad
CoolantTemp

How do I connect it?

Plug the adapter into the OBD port and pair it. Vetkuro runs the ELM327 initialization and detects which PIDs your car answers.

Where it stops

OBD-II is a car standard: most motorcycles and karts have no port it can read, while GPS, cameras and heart rate work on any of them. Which channels appear is decided by the car, not by us. Brake pressure and gear are often unavailable; a 2010 hatchback exposes far fewer than a 2022 sports car.

Cameras

Synced to the lap

Does it work?

Yes: the phone camera, a paired GoPro Hero 9 or newer, or both at once.

What data do I get?

Onboard video tied to the session, so moving the cursor on the delta curve moves the footage with it.

Video
Multi-source

How do I connect it?

Start and stop a paired GoPro from the app, or record with the phone while it logs. Clips attach to the session automatically.

Where it stops

GoPro support starts at Hero 9. Long sessions in the sun are a heat and storage question before they are a software one.

Health / heart rate

Any standard strap

Does it work?

Yes, with any monitor speaking the standard BLE Heart Rate profile, including the strap you already run with.

What data do I get?

Beats per minute stored on the session and readable against lap times.

HeartRate

How do I connect it?

Pair the strap in session setup. If you switch it on, Vetkuro also saves the session and its heart rate to Apple Health or Google Health Connect.

Where it stops

Heart rate explains fatigue, not technique. Useful when the last laps of a stint lose tenths for no visible reason.

How much precision do you actually need?

Sample rate decides how far the car travels between two recorded points. That distance is the resolution of your braking point, your apex and your delta. Set a speed and see what each rate gives you.

Speed at that point on the lap 180 km/h

60 km/hhairpin to back straight280 km/h

1 Hz Phone GNSS

50.0 m

between samples

Half a straight between points. Lap and sector times are right; a braking point falls between two samples.

10 Hz Entry receiver

5.0 m

between samples

A corner entry becomes a handful of points. Fine detail is still interpolated, but the delta lands on the corner.

25 Hz 25 Hz receiver

2.0 m

between samples

Turn-in, apex and exit are each several samples. This is where overlaying two laps starts to pay.

At 180 km/h: 1 Hz 50.0 m, 10 Hz 5.0 m, 25 Hz 2.0 m between samples.

Distance between samples is speed divided by rate: at 180 km/h, 1 Hz puts 50 m between points, 10 Hz puts 5.0 m and 25 Hz puts 2.0 m. A phone is the first row, which is why the receiver is the upgrade that changes what you can read. Published rates vary by device and firmware; check the receiver’s own specification for the exact figure.

Free on iOS and Android

Start with the phone in your pocket.

A phone alone records a complete session. Add a GPS, OBD-II or a camera later. Recording is free, with no lap limit.

What each device class adds to the session.

Everything in the first column is already there with just a phone. The rest is additive, so you can bring one device or all four.

In the session	Phone only	+ External GPS	+ OBD-II	+ Camera	+ HRM
Lap and sector times	Yes	Sharper	No	No	No
Live delta to your reference lap	Yes	Sharper	No	No	No
Driven line on the track map	Yes	Higher resolution	No	No	No
GPS speed and position	Yes	Yes	No	No	No
Engine RPM, throttle, vehicle speed	No	No	Yes	No	No
Engine load and temperatures	No	No	Car dependent	No	No
Onboard video tied to the session	Phone camera	No	No	GoPro, multi-cam	No
Heart rate through the session	No	No	No	No	Yes

Which OBD-II channels appear depends on the car’s own PID support. Vetkuro lists what it detected on your vehicle rather than promising a fixed set.

Getting a session worth analyzing.

Four things that decide whether your data is good enough to compare laps with. All of them happen before the green flag.

Give the receiver sky

Dashboard or roll hoop, not the passenger footwell or a pocket. Heated windscreens and metallic tints both cost you satellites, and a weak fix shows up as a line that wanders through the apex.

Wait for the fix before you roll

The session setup screen shows GPS status and the connection state of every paired device. Leaving the pit lane on a partial fix usually costs you the out-lap and the first flying lap.

Keep Bluetooth short

BLE is happier over a meter than over three, through a body. Keep the receiver and the phone in the same part of the cabin.

Watch heat and storage

A phone recording video in direct August sun will throttle. Shade the mount, keep it charging, and clear space before the day. Video plus telemetry is the largest thing you will record.

The session setup screen before Start Session: the GPS receiver and the phone camera ticked green, the GoPro and the OBD adapter flagged orange as not connected.

In the product

You can see the quality before you drive.

Every device you record with is on the setup screen, with its state: a green tick when it is connected, an orange warning when it is not. Here the GoPro and the OBD adapter need a look, and you see it before you press Start Session, not in the analyzer afterwards.

This is the screen worth ten seconds on your out-lap. A session recorded with a poor fix cannot be repaired afterwards, and no amount of analysis will tell you what you did in the corner where the fix was gone.

Not sure which of these you actually need?

The questions people ask most about devices are answered in one place: phone GPS versus a receiver, whether OBD-II is worth it, which GoPro models work.
