Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
The Weather tab is now a watch-by-watch passage brief:
- Next 24 hours at your position: wind range, peak gusts, squall risk, sea state and comfort, pressure trend, sunset, sunrise and moon - plus a "reef before dark" call.
- 7-day meteogram with wind & gusts, waves & swell, rain and pressure, with night shading.
- Model agreement: ECMWF, GFS and ICON side by side, with a per-day agree/differ badge.
- Passage stats: distance to go, next waypoint, 24-hour run, ETA and whether you arrive in daylight.
- Tropical systems: NHC active storms, forecast cones and 7-day outlook areas on the chart, with distance and threat level relative to your route.
- Works offline: the last brief and tropical data are cached, with their age shown.
Routing:
- Choose the weather model - ECMWF IFS, NOAA GFS or DWD ICON - and compare routes across them.
- Surface currents (set and drift) are now applied in the routing algorithm.
- Wind overlay gusts come straight from the model.
Also: tide stations show live predictions only, and the privacy policy, disclaimer and licences are in About.
