Description

Weather4D PRO is the first application to use the power of GPU for iPad and iPhone to animate the weather like a video. 2D or 3D display is complemented by the continuous scrolling of time which allows to perfectly visualize the evolution of weather phenomena to come. The automatic scrolling can be accelerated or slowed manually by forward or backward in time by simply sliding a finger or by time increments through taps on icons "next / previous".

Global data are based on the 8 day forecast from the U.S. model GFS distributed as GRIB files, and can be complemented by fine mesh forecasts to 96 hours in 1 hour to several areas including western Europe (subscription to WRF). These forecasts are updated four times a day.

Data types:

- Cloud cover
- Precipitations (Rain, Snow)
- Wind 10 m above mean sea level
- Temperature 2 m above mean sea level
- Pressure MSL
- CAPE
- Waves (Height, period & direction)
- Currents

Data models:

- Data from NOAA GFS, NAM, CMC GEM, WRF, FNMOC WW3, MyOcean & Tidetech models, Arpège and Arome models of Météo France
- Forecasts up to 10 day
- Data steps : 3h, 12h, 24h
- Worldwide Cover
- Resolution : 0.025°,0.1°, 0.25°, 0.5°, 1°, 2°
- Data updated 4 times a day (every 6 hours)

In addition to all the functions of Weather4D, the PRO version offers advanced features for maritime navigation:

- Isochronous routing (sailing and motor)

- Importing KML or GPX file type to see the movement of the vessel during weather forecasts.

These files can be created by any other navigation applications like iNavX.

- Prediction passage of the Iridium satellites constellation.

I added in Weather4D Pro the display of the Iridium constellation on the globe in 3D and I implemented a function for predict passage of satellites and a search function for find an appointment and retrieve his GRIB files in conditions of optimum reception.

A search button calculates a date based on criteria defined in the "Options prediction" of "Settings". Two criteria are available:

- Minimum elevation (angle mini above the horizon)
- Minimum time range (minimum time of exposure for the elevation choose)

- The import of GRIB file:

The application accepts files Grib type 1 and recognizes the .grb file and grb.gz,. Grb.bz2 for compressed versions. From mail, Safari or any other applications using the mechanism "Open In" you can import files in GRIB Weather4D Pro. Imported files are stored in a folder reserved for them.

- Historical of GRIB files:

- Personal Folder File GRIB:

- Copy / Paste GRIB file

- Share your GRIB files:

Grib files can be sent by attachment in an email or exported to a compatible application (iNavX, File Connect etc ...) via a menu "Open In"

- SailDocs request by Mail

The data are in the form of stacked layers that can be assembled at will. The fine tunings allow to adjust the readability according to the taste of user: modes display, level of transparency, types of symbols, etc.. A "full screen mode" allows you to use the entire screen area.

Weather4D PRO is a user-friendly application incorporating highly advanced features which are mainly destined for demanding sailors for cruising and racing. It relies on highly accurate forecasts developed for professional use worldwide. A powerful routing module associated with the ability to access currents files GRIB with fine mesh makes this single application in its class.

Does 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

Awesome weather routing and weather app!

methedude

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.

Impressive

I was quite skeptical at first. I watched this app for quite some time and after a couple of updates, I finally decided to take the plunge. I was really thinking it was way overpriced, but after using the app for a few days now, as the title says, I'm quite impressed. It is well designed and after only a few minutes, very user friendly. My only regret, was waiting too long to make the plunge.

The only concern, it must be memory hungry. It will crash upon start until it takes back the memory and then runs like a champ.
