GRIB forecasts are published without human intervention or review. As such, the end user requires some knowledge and awareness. Most GRIB models do NOT accurately forecast hurricanes and tropical cyclones so their use should be combined with specific hurricane and tropical cyclone forecasts.
Great weather app for boaters and doesn’t use huge chunks of data. Very data efficient (although there are other apps out there which are specifically designed to use even less data if you are intending to use Iridium satellite phone). Highly recommend this app for Cell and WiFi use.

We have been using this app for many years now in many different parts of the world during a circumnavigation. Generally it is accurate for a 5 day forecast, with the normal caveats when land can effect wind direction and strength.
Used to be excellent but....

Now the updates to the forecast are slow to arrive, often 6 or more hours behind, which means as a sailor waiting for the forecast before setting off on a passage you are always looking at older data than from other free apps which offer better graphics and more weather models to compare with.No point in buying this app when better free ones are out there.
Easy to use and accurate

I’ve been using this App for several years. I find it easy to use, it’s intuitive design makes it so, it’s about 90% accurate.
