qtVlm for android or iOS is a free grib viewer (assuming you downloaded grib files before losing internet connection). Make sure you also set the maps to offline mode.

I didn't even know such stuff exists.. Basically I thought the only options were sat phone data (expensive) and weather fax with ssb and pactor modem, or just listen to audio forecasts on your radio.. And I recall in US you can sub to wx on your plotter (some), but again, these actually do connect to internet.. I believe..
So how can an app get a FOREcast if there is no internet connection? Sure can display old downloaded ones but how about new fresh ones?
Keen to learn more..

There's an app that shows forecasts by comparing the clouds (and wind) amongst other things :
Weather Navigator

I just downloaded it. (US$2.50).
Its 25 photos of clouds and a write up of each.

I don't think the developer will become a millionair from it.

Weather4D PRO and Weather4D 2.0 allow to get GRIB files for offshore use :
- From internet before cast off (all forecast models GFS WRF NAM WW3, etc)
- From SailDocs with satphone (GFS)
- Direct download with Iridium GO! (W4D 2.0 only, all forecast models)

PredictWind. I've tried them all and this one's the best.

Before I subscribed to PredictWind, my first choice was Weather4D Pro.
