Capmate keeps the anchor watch, shows your boat's instruments and plans the passage — on your phone and on your wrist. The chart and the anchor alarm work without internet.
Anchor, instruments, chart, weather, traffic and places to stay — on the phone and on the watch.
Screens are from the current test build, which is in Russian.
Anchor watch
Sleep while Capmate keeps the watch
Enter the depth and Capmate works out how much chain to let out for the forecast gusts and sets the alarm circle. Then it watches the boat in the background: swing track, distance to the anchor, drift. If the anchor drags or GPS is lost, the phone and the watch sound the alarm.

Loud alarm on the phone and the watch
Boat instruments
Your plotter's data, anywhere on deck
Capmate joins the boat's Wi-Fi and reads the chartplotter over NMEA 0183: depth, apparent and true wind, speed through water, heading and the boat's AIS. Glance at your wrist instead of walking to the helm.
Tested with B&G Zeus3
Any plotter or gateway that streams NMEA 0183 over Wi-Fi
True wind calculated on board
Chart and routes
Three ways to get there
An offline nautical chart with depths from EMODnet and GEBCO, downloaded by region. Pick a destination and Capmate offers three routes — under sail, under motor and the best mix for the forecast — then guides you like a car navigator, with a vibration before every change of course.
Wind, gusts, waves and rain on the chart, hour by hour. Official warnings from AEMET and IPMA, the pressure trend with a storm alert from the barometer, sunrise, sunset and the moon.
Animated wind on the chart
Hourly wind and gusts for two days
Barometer storm alert on the watch
Vessels nearby
Know who is heading your way
AIS targets from your own receiver and from the internet, with the closest point of approach and an alarm when someone gets too close. In the marina Capmate stays quiet and turns the alarms back on once you are at sea.
Bays and marinas
Find a good spot for the night
Search marinas, anchorages, bays and fuel docks without internet. A bay card shows how sheltered it is now and overnight, the depths and what is nearby.
Watch
Built for the watch, not squeezed onto it
Big numbers, buttons for wet fingers and a red night mode. The most important actions are one press away.
Man overboard in one press

Questions
Does Capmate replace my chartplotter?
No. Capmate is a navigation aid for the crew. Keep official charts, the boat's instruments and a proper watch on deck.
Which chartplotters does it work with?
Any plotter or Wi-Fi gateway that streams NMEA 0183 over the boat's network. We test with a B&G Zeus3. Raymarine and Garmin plotters usually need a Wi-Fi gateway.
Do I need internet at sea?
Not for the chart, the anchor watch, the instruments or your saved points. Weather, warnings and AIS from the internet need a connection, and the app shows how fresh each piece of data is.
Does the anchor alarm work in the background?
On iPhone and Android, yes, with a loud alarm. On Garmin watches the watch keeps guard while Capmate is open on it; the phone keeps watching either way.
Which watches are supported?
Garmin fēnix 7, epix (Gen 2 and Pro) and Forerunner 265 — 14 models in total — plus Galaxy Watch and other Wear OS watches. Apple Watch comes next.
When can I get it, and what will it cost?
Capmate is being tested on real boats now. It will be released on the App Store, Google Play and Garmin Connect IQ; the price will be announced at launch.
What languages does the app speak?
The test builds are in Russian. English, Spanish, Portuguese, German and French are being added before the public release.
Built on the water, not at a desk
Every feature has been tried at anchor and under way. Capmate is coming to the App Store, Google Play and Garmin Connect IQ.
