CapMate puts an anchor watch on your wrist
CapMate is a boating app in testing that brings anchor-watch alerts and boat-instrument readings to Apple Watch, Wear OS, and Garmin devices.
- For
- Sailors keeping watch at anchor
- Worth noticing
- The site says the watch monitors its own GPS, battery, phone link, and app status, raising an alarm if one fails.
Field notes
The described anchor-watch system is designed to alert on the wrist and use the phone as a loud backup, while also watching for failures such as lost GPS or a broken connection. Instrument readings are meant to come from chartplotters or gateways over NMEA 0183 Wi-Fi; the site lists several brands and says some require a gateway. The homepage says testing is underway on real boats, so the described capabilities should not be read as confirmation of general availability.
