Frequently asked questions

How does the knots speedometer work?

It reads your speed directly from GPS and shows it in knots (nautical miles per hour), updating in real time as you move. Everything runs in your browser — your location never leaves your device.

What is a knot exactly?

One knot equals one nautical mile per hour, which is about 1.852 km/h or 1.15 mph — the standard speed unit used internationally for boats, ships and aircraft.

Does this work on a boat with no phone signal?

Yes — GPS works independently of mobile signal, so it'll track speed as long as your device has a GPS receiver and a clear view of the sky.
