## What is WeatherTrack GRIB?

WEATHERTRACK 
Amazing Weather Details at your Fingertips. Worldwide.

"An incredibly comprehensive weather app - it accesses many data models from different agencies and provides worldwide coverage. The GRIB layers include wind, precipitation, wave height/direction/period, ocean and tidal currents, air and sea temps, relative humidity and more. WeatherTrack works offline, and GRIB files can be downloaded through an SSB connection, an Iridium AxcessPoint or as an email attachment and opened in the app." (App of the month! in Cruisingworld)

### 1/5 — Issue

*2025-06-08*

I just bought it but the App crashes every time I open it.
Any suggestions?
Thanks.

### 4/5 — Error 404

*2025-05-28*

Error 404. An error keeps appearing while loading the weather.

**Developer response:** That was due to RTOFS data not available via NOAA. There was a change in the data distribution there.

### 3/5 — Blocage de l’application

*2025-05-15*

L’application se bloque au moment du téléchargement d’un modèle de courant, RTOFS ou autre: Erreur 404 sur l’url.

**Developer response:** This must have been a temporary problem, we just used RTOFS in the western Caribbean.

### 1/5 — Ужасное приложение!!!

*2025-02-14*

Просто выкинул на ветер 900р, мало того что приложение стоит 900р, так что б оно работало нужно еще купить кучу внутренних подписок! 
Очень жаль что AppStore пропускает такие приложение! Ужасно, не ведитесь!

### 5/5 — Superspitze!!

*2021-07-14*

Genialste Wetter App. Mit der Kartenauswahl ein unübertreffbares UserInterface. Die GRIB-Files sind entsprechen minimal zu halten und eh winzig (Datenvolumen!). Mit 1 Klick ist der Angezeigte Bereich aktualisierbar. Mit den Detaillierten informationsebenen lässt sich präzisestes weather routing betreiben. Viel Spielraum um tiefer in die Materie einzusteigen (Informationsquellen etc) mit sehr guter Hilfe! Top Punktzahl in Platin mit Exzrasternchen. Vielen Dank den Machern!!
