iPhone

A live Lock Screen tracker for every storm night, and alerts tuned to your own sky. Screenshots show an illustrative storm night, not live data. Know tonight's chance of seeing the aurora where you are, and never miss a storm night. Polarglow reads the sky over you: the chance of aurora overhead, the clouds and the darkness, side by side, over a live sky that moves with tonight's Kp. The Kp forecast for the next three nights shows which night is worth staying up for. FREE - Tonight's chance for your rough area, with clouds and darkness - The current Kp and the three-day Kp forecast - One alert when a strong storm (G3 or stronger) reaches you POLARGLOW PLUS - The storm-night tracker: a Live Activity on your Lock Screen and in the Dynamic Island that starts on its own, follows the storm and leaves at dawn - Alerts for your own sky: your threshold, only when it is dark, only under a clear sky - Up to 5 places: home, the cabin, the trip next month PRIVATE BY DESIGN Your exact location never leaves your iPhone. Only a rough area of about 100 km is used to watch the sky. No account, no sign-in. Polarglow Plus is an auto-renewing subscription, billed yearly or monthly. It renews automatically unless cancelled at least 24 hours before the end of the period, and you can manage or cancel it in your Apple Account settings.
