## What is Weather4D Lite?

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.

### 5/5 — La Rolls

*2025-09-13*

L’interface est particulière mais aussi très configurable et finalement intuitive. 
Et perso, j’adore pouvoir faire défiler le temps manuellement et voir l’évolution de l’ensemble des valeurs météorologiques. 
Et si on se contente du modèle de base, car je ne navigue pas, c’est un achat unique.

### 5/5 — Commercial Pilot, favorite overview app

*2021-08-12*

This is a wonderful app! As a pilot and flight instructor I use this app for long term prediction. The graphical interface has almost limitless settings for including or removing visible data. I have been disappointed by every weather app I've downloaded, until this. Lives on my home page. (Did the negative reviewers even understand the most basic aspects of weather prediction?) If you want simple idiot mode weather, most other apps will be fine. If you want beautifully depicted graphical prediction models, this is it.

### 5/5 — Superbe application + une étoile même.

*2020-02-25*

Application remarquable... merci Olivier.
A chaque fois que je la lance de temps en temps, je suis toujours bluffé. Par contre je ne parviens plus à faire apparaître les menus latéraux.

### 1/5 — Don’t Ugrade!

*2018-06-16*

The first Weather 4D lite was wonderful, but the upgrade to Weather 4D lite is very unstable, crashing constantly.  Don’t hand over $49.00 to an entity whose upgrades are disfunctional downgrades.

### 1/5 — Updated version sucks!

*2018-04-13*

This app used to be great, easy to use. Now, it’s useless!

### 1/5 — keeps crashing. a waste of 10 dollars

*2016-10-30*

app keeps crashing on iphone7 plus. started only the first time.

### 4/5 — Weather4D

*2015-08-05*

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.

### 5/5 — Download and view GRIB data

*2014-07-26*

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.

### 5/5 — Great source of obtaining gribs & understanding weather systems

*2014-02-27*

We have been using this app for sometime helping plan passages on our sailboat.  In addition I have been using it as part of my daily weather forecast given to the vessels in western Panama.  

One of the better ways to put gribfiles into an animated stream

### 4/5 — Bon concept MAIS

*2013-09-15*

La réactivite de l'interface est un peu déroutante.  Pour faire apparaitre les menus d'affichage des différents calques c'est tres difficile. En fait il faut faire un double tap MAIS au centre de l'ecran.  Développeur moi même, je trouve certains choix de gesture etranges on aurait pu mettre tap 2 doigt pour faire apparaitre les menus...
Le coup du iBook payant pour apprendre à se servir d'une app iOS tactile je trouve ca un peu poussé, mais j'imagine que ca concerne la version pro. Sinon le développeur est tres réactif sur le support technique donc je remonte la note de mon premier com. Il y a effectivement plein de fonctions enfouies assez profondément dans l'UI mais tres utiles.
