Frequently Asked Questions

Common questions about Sondex, subscriptions, and supported data.

What is BUFKIT? Why is it mentioned?

BUFKIT is a standard forecast profile format originally developed by the National Weather Service. It contains detailed vertical slices of the atmosphere from specific forecast models (like the GFS or HRRR) for a specific location. Sondex imports these files to render its interactive charts.

How does Background Auto-Fetch work?

Sondex Pro utilizes iOS and macOS background refresh capabilities to quietly update your pinned stations. When you open the app, your favorite data is already perfectly synced and ready to view instantly.

Can I use Sondex offline?

Yes. Once data is imported or fetched, it is cached locally. You can analyze soundings, view 12 different chart types, and export images completely offline, making it perfect for field operations.

What is the difference between Free and Pro?

The free tier includes complete access to all charts, indices, and weather models with manual data fetching and 1 auto-fetching station. Pro unlocks unlimited automatic background fetching, infinite file imports, premium themes, and custom station creation.
