LuckGrib for iOS

LuckGrib is a fully featured, easy to use, fast GRIB reader, viewer and downloader

LuckGrib comes with a 14 day free trial. If you are interested in studying weather and gaining access to detailed weather forecasts, download the app and give it a try. Note that LuckGrib does not use a subscription pricing model - after the free trial when you decide to purchase the app there will be a one time charge, not an ongoing subscription.

LuckGrib uses beautiful and fast graphics to give you insight and understanding into how the weather and ocean conditions will change through a forecast as well as showing you the details of what happens at any location.

Weather forecast data, packaged as GRIB files, can be downloaded directly from the LuckGrib server cluster. Downloads from the server cluster are fast - you can easily explore the weather world wide using some of the best weather models available.

All direct high-speed internet data downloads are free. You have immediate access to over 30 weather and ocean models.

With the optional Offshore Data in-app purchase, sailors, and other remote users, are able to download weather data while in the "middle of nowhere", some of the most beautiful places on the planet, via satellite or email downloads. There is a separate 14 day free trial available for the Offshore Data service. See offshore.luckgrib.com for more details.

Weather models are available which contain surface conditions, wave and swell state, ocean currents as well as higher altitude information such as that found at the 850mb, 500mb and 250mb levels - these levels correspond to the low cloud level or jet stream, for example. Some of the models available are: GFS, GDPS, CMC, WW3, HRRR, RAP, NAM, NDFD, Icon-EU, Arpge, Arome, OpenWRF, RTOFS

Check the support site for additional information regarding model availability. Short videos are also available, as are tutorials and other information
