Never miss the northern lights again.
Northern Lights Tracker tells you whether tonight is worth going out, when to look and where to go. It turns live NOAA space weather data into one clear aurora chance for your exact location.
Tonight at a Glance
• Aurora chance for your location, updated live
• A clear verdict, from "Go look now" to "Not tonight", with activity, solar wind, moon and cloud factors
• Best viewing time and the best 2-hour window
• Current Kp index and a 3-day Kp outlook
• Search any place and save your favorite spots
• Share tonight's forecast with friends
Aurora Alerts
Get notified when the aurora is likely where you are. Choose a chance alert, a Kp alert, a storm early warning up to 24 hours ahead, or a solar wind (Bz) alert with your own threshold. Chance and solar wind alerts wait until it is dark, and quiet hours keep your nights undisturbed.…

No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured

From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
