This is the info from the website:
mobileGRIB is a GRIB2 viewer for Android. It enables sailors and hobby meteorologists to have detailed weather information always available. This is done by downloading GRIB files of any region of interest. Source for the Gridded Binaries is the National Oceanic and Atmospheric Administration (NOAA). Forecast times and variables can be chosen from pressure, wind arrows, temperature, cloud cover, humidity and precipitation for the upcoming 6 days and between a resolution of 1° x 1° or, for even more detail, 0.5° x 0.5°. By selecting only what the user needs, this procedure will keep the size of the downloaded GRIB file low, making it especially convenient for low bandwidth regions covered only by Edge or GPRS networks, or simply regions with low cellular coverage.
A free version of mobileGRIB is available under the name of mobileGRIB light and can be used for evaluation purposes. It is a fully functional version with outdated GRIB files. To receive actual GRIB forecasts, please purchase the full version.
remember zoom level
choose forecast interval and period before downloading the GRIB file
offline maps for even less data transfers
offline GRIB file browser
GPS positioning and track
Latitude and Longitude lines
L and H signs for pressure
Isotherms to determine cold and hot fronts and resulting occlusions
language support for up to 9 languages
