SolarStorm

iPhone / Météo

SolarStorm turns live data into a clear, beautiful read on what the Sun is doing right now — and whether it matters to you.

Solar flares, geomagnetic storms, and radiation can disrupt GPS, radio, satellites, and power grids — and light up the sky with aurora. SolarStorm makes it simple to follow.
