Squid Mobile is a free and powerful weather app specifically designed for sailors. Developed by The Great Circle SPRL, it is the easiest and most comprehensive requester and viewer of Grib Files (weather files) available on the market. Whether you are a casual cruiser, a competitive racer, an offshore solo navigator, or a coastal dinghy sailor, Squid has all the forecast data you need.

With Squid Mobile, you have access to the best possible accuracy in weather forecasts, covering any region around the globe. The app offers a wide range of models such as GFS, ECMWF, HiRLAM, AROME, ARPEGE, GEM, GCWF, NAM, and more. You can compare and analyze con-divergences with the multi-model viewer, and use the routing and way-point editor with features like bearing Compass, boat polars database, roadbook reporting, cloud routing, and multiple road comparisons.

Squid Mobile also provides up to 10 days forecasts by steps of 1 or 3 hours, allowing you to plan your sailing trips with precision. You can easily download the Grib files directly or as mail attachments for sharing and opening in other applications. The app also offers multi-model meteograms for easy comparisons of MSLP and wind.

With customized views by color gradients, isolines, barbs, and arrows, Squid Mobile combines both CPU and graphical processor for smooth animations. It is compatible with iOS9 and also supports Iridium GO!® for seamless connectivity at sea.
