Boat speedometer with knots, km/h, mph, and m/s
Use zigmaty as a boat speedometer with knots as the natural marine unit. You can also switch to km/h, mph, or m/s while tracking distance, time, average speed, max speed, GPS accuracy, alerts, and local history.
Boat mode defaults well with knots. Keep the phone dry, secure, and where it can receive clear sky GPS signal.
Common questions
These answers cover accuracy, privacy, installation, units, and the best way to use this page.
Does boat mode support knots?
Yes. Boat mode is designed for knots and also supports km/h, mph, and m/s.
Can I convert knots while tracking?

Does it work offshore?

No. It is a simple GPS speedometer, not a navigation or safety instrument.
Can I save boat trip summaries?
Yes. Stopped trips can be kept locally on the device and cleared later.
