Amazing Weather Details at your Fingertips. Worldwide.

"An incredibly comprehensive weather app - it accesses many data models from different agencies and provides worldwide coverage. The GRIB layers include wind, precipitation, wave height/direction/period, ocean and tidal currents, air and sea temps, relative humidity and more. WeatherTrack works offline, and GRIB files can be downloaded through an SSB connection, an Iridium AxcessPoint or as an email attachment and opened in the app." (App of the month! in Cruisingworld) (at a glance)
