Aurora Forecast Tracker for iPhone

Brief overview

Aurora Forecast Tracker is a free iPhone app built for people who want to see the Northern Lights. It delivers live updates on aurora activity and offers tools to help you decide when and where to look. The interface focuses on practical information so both casual viewers and serious chasers can plan outings with confidence.

Core capabilities

• High-precision KP index predictions derived from NOAA satellite inputs, giving a reliable basis for planning.
• An interactive, zoomable aurora map that shows current activity and short-term projections to help choose viewing locations.
• Location-based probability estimates that adjust for magnetic latitude and seasonal shifts, improving forecast relevance.
• Smart notifications that inform you of daily outlooks, strong KP events, and possible sightings within the next hour.
• A searchable archive of past forecasts and curated lists of recommended vantage points for viewing the lights.

Alerts and push notifications

The app’s alert system can be customized so you only receive the notices you care about — for example, high KP warnings or short-term sighting opportunities. Notifications are intended to be timely and actionable, so you won’t miss a brief window of activity.

Forecast accuracy and data sources

Forecasts are calculated using space-weather inputs from NOAA satellites and presented as KP index estimates. That data backbone helps ensure the app’s predictions are rooted in current geomagnetic conditions rather than anecdotal reports.

Map tools and personalization

The mapping features let you visualize both present auroral bands and near-term forecasts overlayed on a geographic map. Personalization adjusts probabilities based on your exact location and environmental factors, so the app suggests when your spot has the best chance of activity.

Planning aids and historical records

Save forecasts, review past activity, and discover top viewing sites suggested by the app. These planning tools are designed to help you pick nights with higher odds and to learn from previous conditions.

Paid alternative

If you’re open to a paid option, consider a dedicated weather-and-aurora service that combines specialized forecasts with advanced planning tools (many paid apps offer expanded radar layers and extended alert customization).
