Everything you need to catch the northern lights — in your pocket.
Get alerted the moment aurora probability crosses your threshold — so you never miss a display.
Alerts only fire when the sky is actually clear. No point waking you up when it's overcast.
Set your exact location — whether you're in Reykjavík, Tromsø or Fairbanks, alerts are calibrated to you.
Choose your sensitivity: alert at 50%+ (frequent) or only at 90%+ (exceptional nights only).
KP index, Bz, solar wind speed and cloud cover — always fresh, refreshed every 2 minutes.
Find the clearest spot in Iceland tonight with our live cloud cover map and per-location scoring.
Free on the App Store and Google Play. No account required to get started.
Choose your location or let the app use GPS. Works anywhere in the aurora zone.
Choose how sensitive you want alerts — from 50%+ (frequent) to 90%+ (only big nights).
When conditions align — KP up, clouds down — the app wakes you up. The rest is up to the sky.
Join thousands of aurora hunters who never miss a display. Available for iPhone and Android.
