## What is Beamback?

Beamback is the offline GRIB weather viewer for your ZOLEO. Request a marine forecast, receive it as satellite text, and see it as a live, interactive weather chart. No internet, no account, no tracking.

Built for sailors, cruisers and anyone offshore who needs real GRIB weather where there is no signal.

HOW IT WORKS
Out at sea you have no internet, but your ZOLEO still sends and receives text over satellite. Request a forecast, copy it, and send it from your ZOLEO. The reply comes back as message chunks. Paste them into Beamback and it decodes the GRIB and draws it on the map: wind, pressure, rain and waves. Everything runs on your phone.

FEATURES
- Copy a weather request and send it from your ZOLEO
- Paste the GRIB message chunks you receive and decode them 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 on the map to read exact wind, pressure and wave values
- 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 GRIB chart right away. No ZOLEO needed to try the app.

Requires a ZOLEO satellite device to send and receive messages. Beamback is an independent app and is not affiliated with ZOLEO Inc. ZOLEO is a trademark of its owner.

Weather model data is GFS (NOAA) and ECMWF.


## Version history (last 2 releases)

### 1.1 — 2026-07-27

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. Beamback is an independent app and is not affiliated with,
endorsed by, or sponsored by ZOLEO Inc., Garmin Ltd., or any messenger maker; all
trademarks belong to their respective owners.

Weather model data is GFS (NOAA) and ECMWF.
