Apple Watch apps
Pocket Mariner, developers of Boat Beacon, SeaNav and several other tablet and smartphone sailing apps, now provides Apple Watch functionality. With SeaNav, the navigation program, Apple Watch shows waypoints, cross-track error, ETA and distance. Other screens show AIS targets, a compass and flashlight with night-mode.
Apple Watch functionality comes free with most Pocket Mariner apps; SeaNav for iPhone is $19.99. Read more about how the splash-proof Apple Watch works with Pocket Mariner apps at the Pocket Mariner website.
