About this app

reChain Grib is the simplest way to download GRIB weather files when sailing offshore with a Garmin inReach device.
Designed for skippers who need reliable, lightweight, and fully offline weather tools, reChain Grib helps you stay informed even when you’re far from any connection.

-> Generate GRIB Requests

Create precise GRIB weather requests (wind, pressure, waves…) using a clean and intuitive interface.
Just copy your request and send it via your inReach to a specific email—no internet connection required.

-> Decode GRIB Chunks

Paste the GRIB chunks received by your inReach, and reChain Grib automatically decodes them into a downloadable GRIB file.
Open it with any GRIB viewer on your device.

-> Designed for Offshore Use

• 100% offline
• Extremely lightweight

-> Why reChain Grib?

Because offshore weather access should be simple, reliable, and available anywhere.
Whether you’re crossing an ocean or sailing along the coast in a remote place, reChain Grib gives you the essential tools to request and view weather whenever you need it.
