THE STORM GLASS

What is the glass showing?

Stormglass uses the old storm-glass visual language as a weather display, not as a chemical forecast. The bottle is driven by the app’s real weather data.
REALITY CHECK

What’s really happening?

Forecast chance is not the same thing as what is falling on you right now. Stormglass compares fresh local signals and lets your own observation count.

Waiting for a live check.

Your precise GPS is used only for this live check and is not saved by Reality Check. Nearby NWS observations can lag behind what is happening at your exact spot.
