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.

Tried to get a refund but that was declined so I’ve wasted $40 for nothing.. do not download ### 4/5 — Great app - no support *2024-05-21, version 2.0.58* This is a fantastic app for weather geeks. I have been using it for years now. It is a great pity that, though expensive, the authors no longer respond to tech enquiries. As of the latest version, there are outstanding issues, so we just have to wait and hope. ### 1/5 — Non accès à l’application… *2023-07-26* Débite de 46,99 € le 25 juillet. Impossible d’accéder à l’application, comment faire ? ### 3/5 — Bonne appli mais upgrade trop cher! *2022-01-03* L’appli donne toute satisfaction même si l’ergonomie n’est pas toujours intuitive. La puissance de l’appli donne envie de prendre la version Weather4D Routage & Navigation mais… l’upgrade (bundle 17€) pour la version Weather4D Routage & Navigation est impossible à activer ! Il faut donc payer toute l’application à 55€… Cela fait cher quand on a déjà acquitté les 38€ de la version Routage. ### 5/5 — Previous review not correct... *2019-07-02, version 2.0.44* Had problems when first loading Weather4D Pro with routing problems similar to previous reviews. Corrected fault by switching downloads via mobile data ON. No further problems so far. Great app well done... ### 5/5 — Excellent *2018-08-19* Appli extrêmement complète pour naviguer au quotidien, avec météo (plusieurs modèles au choix) et routage de qualité. Pour la prise en main, il est indispensable de suivre le tutoriel complet réalisé par Francis Fustier, mais ensuite, l'appli devient facile d'utilisation. Bravo à Olivier Bouyssou pour cet outil remarquable ! ### 5/5 — Excellent *2018-07-18* Beau travail d’affichage, belle évolution avec les routes intégrées et la gestion des waypoints et avec tous les modèles dispo pour un abonnement dérisoire, le routage est top. ### 2/5 — Made a mistake upgrading *2018-07-02, version 2.0.40* Hello folks I updated my Routing version, cannot access waves anymore. Need to provide user and register an account. When I try to register or create an account, it always say "invalid account". Tried to get one valid account from support and their responses does not work... ### 2/5 — What gives *2018-06-17, version 2.0.40* I just upgraded and now using the new version. I'm only able to access one weather model, GFS only. One only, many of these models are free - elsewhere and were free on my previous version of this app. This sucks. Money grab? Shame on you! ### 1/5 — Frustrating! *2018-05-07, version 2.0.39* I've used weather4d for a couple of years and appreciated its interface and detail. However, the app was recently updated and is now virtually un-useable. Within minutes of switching on the tool bar changes so that it shows the time of the forecast but not the date and the option of creating new weather charts just disappears. I've deleted and re-loaded the app several times - the same happens, works for a few minutes and then lose date and options part of tool bar. ## Frequently asked questions about Weather4D Routing ### What is the primary function of Weather4D Routing?
