Weather4D Routing is an outstanding meteorological and routing application 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 benefits from an interface derived from the “Routing & Navigation” version. Weather GFS model is provided by default. In addition, over 35 weather and oceanographic models are available with a yearly subscription (in-app purchase). 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 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. Routing 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.

Cautiously optimistic
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)
United StatesUnstable 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...
United StatesDoes not work
Do not buy it if you have an IPhone (7 plus in my case) as it is not possible to open the app
United StatesNo support!
I;’ve been trying to write the developer on their website but their stupid CAPCHA system is so hard to read (3 friends tried too!) that I have to leave my support request here in the hope he will answer: ======= I bought your program and have used it since v1. Since I upgraded to IOS 8.1 I get a message now about having to pay you $33 for a HD weather forecast or else the program stops working. It[’s useless now unless I pay you an additional $33. I just need the basic weather not any HD stuff. I already paid your $30+ for the program. Can you look into this for me? Thanks, Art
United StatesGreat app for sailors
I have taken multiple cruises across the Gulf of Mexico and found this app invaluable. Being able to plan out the best route days in advance given wind conditions and avoid choppy waters has come in handy on many occasions. This type of software isn't cheap for a pc - amazing what you get for the price.
United StatesWell Worth It.
I don't normally write reviews, and as an IT Consultant and avid sailor, I had to comment. This app is great once you get the handle on how to use it. First the App is excellent in getting a view of sailing conditions in my South Florida region. Not only do I get wind, etc but I also get current data which is important for any Gulf Stream crossing. I use OpenCPN on Linux, and can easily transfer the routes between the iPad and Weather4d, that's handy when I am preparing at home or on the boat. I also use qtVlm on Linux (weather routing) and but have not compared the calculated optimum routes as yet. I would like to know if the app takes into account current as well as wind and boat Polars, but I can work that out myself. The main benefit to me is to be able to visualize the boat in a crossing over the calculated route time using the time function to pinpoint any adverse conditions in a visual way, from this perspective this app really excels. The animation is first class. I save the GRIB files from Weather4d, import them into qtVlm or other applications on my Linux laptop, and viola I have all the wind, wave and current data I need. Lastly, support from Olivier is excellent. I had a problem on saving my GRIB files in the last release, and to my surprise I got an email back within 24 hours telling me he had fixed it, and guess what, he did. Awesome! For weather routing, I can't comment at this stage, but just for the our visualization of the route it's worth the cost. Everything else is a bonus.
United StatesVersion 1.3 "missing"
Version 1.3 of this app can apparently do full isochrone routing, and the text in the App Store says that 1.3 is the current version. However, when I paid and downloaded the app I got version 1.1, which ones NOT do routing, and the App Store says I have the latest version. So it appears that the version actually in the store does not match the text description.
