This video shows an Android tablet decoding and displaying HF weather fax that was received on a shortwave radio. It's easy to do. Just put the tablet or phone next to the radio's speaker or headphones, and the app automatically starts displaying the image. You can receive weather fax on your boat or ship without an internet connection, just with your SSB marine radio.
