Open iTunes to buy and download apps.


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)

Official partner in the AMERICA's CUP TEAM ARTEMIS (2013)

I drive a 54 meter sailboat for a living, I love this app, I use it to show the guests what to expect on a crossing.
Couple of points, do we really need to show the year and month in a weather app with a 6 day forecast, can we swap that space for the day of the week?
Keep up the great work

Amazing App Get It!

Incredible tool for offshore passages with internet capability. Import route features from other Nav apps providing weather at different stages of passage. Highly recommend even for those planning a trip prior to departure.
