Weather4D Lite is a powerful meteorological application based on atmospheric and oceanic data in GRIB format. It benefits from an interface derived from the “Routing & Navigation” version.
View combined weather data displayed in 3D HD layers animated automatically or manually by sliding a finger on the screen.
Use GFS model to get started. In addition, over 35 weather and oceanographic models are available with a yearly subscription (in-app purchase).
Create your own geographical zones, select the models you need and download only the characteristics that matter to you: data type, resolution, periodicity, file size, etc. GRIB files can be downloaded anywhere through a regular or satellite internet connection.
Split the screen (iPad only) to combine and/or compare: navigation and weather, weather and waves or currents, two weather models… The splitted screens can display charts at different scales.
Create or import locations, combine them with GRIB forecast models and get a holistic view of the sea conditions.

An excellent app. Invaluable for recent passages across Biscay, Brest-Baiona, and onward via Lisbon, Gibraltar and Calpe, to Ibiza.It may take some time to learn the nuances of the user interface, but it then allows you to setup areas of interest, download GRIB data, and visualise projections for wind, weather, waves and currents in various combinations.Many thanks to L'Échappée Belle (a well-travelled Harlé Jurançon) for pointing us to this app in Morgat (Brest) on 5 Jul 2014.

This is certainly the best GRIB file viewer that I have used (and I have tried most of them!) It is very feature-rich and well worth spending time getting to know. In addition to displaying the standard (free) GRIB Files there is an option to purchase a higher resolution WRF model. Well worth the extra if you intend to use it for any serious sailing. Support questions are answered promptly and clearly.

Just downloaded this app, really impressed. I love the way you can set up new geographical areas with such ease.
