Beamback turns marine weather sent as plain satellite text into a real, interactive GRIB chart, completely offline. Built for sailors, cruisers, and anyone off the grid. HOW IT WORKS Offshore you have no internet, but you can receive text messages on a satellite messenger. Beamback reads those messages, decompresses the encoded GRIB forecast inside them, and draws it as a live weather map, wind, pressure, rain, and waves. No connection at any step. • Paste the reply you received and Beamback decodes it on-device • Wind barbs, pressure isobars, rain and wave overlays on a dark, offshore-friendly map • Scrub hour by hour through the forecast • Tap anywhere to read the exact values at that point • Save the raw GRIB file to open in your other navigation tools 100% OFFLINE The world basemap is built into the app, so it works with no signal, at the nav station, mid-ocean, in Airplane Mode. Nothing is uploaded. No account, no sign-in, no tracking. TRY IT WITH NO DEVICE Tap "Load sample forecast" to see a real decoded chart immediately, no satellite messenger needed to try the app. WORKS WITH YOUR SATELLITE MESSENGER Beamback reads weather text received on any satellite messenger, including ZOLEO and Garmin inReach devices.
