Sextant
Sailing companion
A sailing companion for iPhone and Apple Watch: live wind, tides and tidal currents, a wind-routing engine, and an offline boat logbook with engine hours — plus a man-overboard button, an Apple Watch app, and home-screen widgets.
Marine weather & wind
Hourly wind speed, gusts, and direction, with a simple sailing-quality read on whether it's a good day to go out.
Tides & tidal currents
Tide heights through the day and tidal current set & drift at your spots, so you time the gate and work the current.
Wind routing
Pick a destination and Sextant computes fast sailing routes from the live forecast using an isochrone router and a boat polar.
Weather-window alerts
Get notified when a good sailing window opens up, so you never miss the day the breeze fills in.
Boat logbook
Record position, conditions, and engine hours. Offline-first, with optional Sign in with Apple to sync across your devices.
Man overboard & Watch
A man-overboard button that tracks a position in the background, plus a full Apple Watch app, complication, and widgets.
