Weather4D Routing is the successor to Weather4D Pro. This eminent meteorological and routing application is based on weather and ocean data in GRIB format as well as the speed characteristics of the sailing boat (polar) and its minimum speed when operated with its engine. It now benefits from a new interface derived from the “Routing and Navigation” version.
Over 35 weather and oceanographic forecast models are available. Queries and downloads are fully customizable.
The application makes it possible to create your own geographical zones and to select the characteristics of the GRIB files to download: choice of data, resolution, periodicity, file size, etc. GRIB files can be downloaded wherever you are from our servers through a regular or satellite internet connection.
Weather4D Routing & Navigation displays the combined data as layered layers. All the data of a selected model is displayed by an animation in continuous time scrolling or in manual scrolling on the map.
The weather forecast is displayed in one or two windows (iPad only), offering several display combinations of the same area: navigation and weather, weather and waves or currents, comparison of different models. The two windows can be disassociated for displaying the same area at different scales.
Weather4D Routing makes it possible to optimize sailing or engine, or mixed sail-engine routes. From a theoretical route, a routing algorithm will take into account wind force and wave height constraints. When sailing, the boat polar combined with wind and current forecasts will be used to optimize performance, comfort and safety.
Several routes can be displayed to compare the outcome of different options: different forecast patterns, departure dates and times, selected constraint values. The routing can be restarted at any moment during navigation from the actual position of the boat.

Ratings and Reviews
Update: While the new app is not intuitive and lacks the useful, exportable grib files via email, the responsiveness and helpfulness of customer service from Frederic to solve problems and assist in learning this new software is EXEMPLARY. We are hopeful that once we learn the new functionality of Weather 4D we will like it as much as we did Weather 4D Pro (the older version)
Unstable release with serious bugs
I was happy to see that there was an update on the weather4D app so I downloaded the latest release of it... Unfortunately the app crashes either right after startup or, after 5-6 restart attempts, as soon as you click on any of the buttons (I.e. Settings). I tried it on an iPad Air 2 with all other apps forced off (to ensure that the bug is not due to low memory).
It used to be a great software some years ago (good graphics) although the navigation through the globe was not very intuitive.
Hopefully there will be another update soon that will address the current "crashing" issue.
3 stars as motivation to work on a fix...
Awesome weather routing and weather app!
Don't know what happened to my lengthy first review. Seems to have just disappeared. So here is the short version. This app ROCKS! The weather predictions have been spot on and the weather routing is impressive. Speaking of impressive, the authors availability! I had a concern about routing and emailed him. He replied almost immediately (considering he is in Europe and I am in the States) and advised why it wasn't working and that he would have it fixed in the next release. The issue was that I was trying to route and there was some land in the way. Even though I went around it, the program could have used it and therefore failed. He has it excluded now and all works wonderfully. Again, TOP NOTCH. Yes, the price is more than your usual app, but this is a PRO app. It is substantially less than my last weather routing program by a few thousand. Yes, THOUSAND.
