Latest questions about "zygrib"

I have downloaded zyGrib with success on my Mac, but I tried on Mac Airbook and the installation was unsuccessful. I can't see the map in the background and cannot choose an area to download.

I am crossing oceans and I need a reliable weather forecast which will be downloaded to Iridium Go via satelite fast enough. It should not cost much.

When will there be an iPad version of Zygrib? Where can I find it?
