For a simple free alert, My Aurora Forecast & Alerts is the least complicated starting point. For threshold controls and a highly local, short-range view, Aurora Forecast & Alerts offers the most configurable forecast display. Aurora Forecast adds community reports, webcams, a dark-sky finder and wearable support. SpaceWeatherLive is the better fit when you want space-weather context and written reports rather than an aurora-only interface.
None of these services can promise that you will see the northern or southern lights. Their alerts describe predicted activity; darkness, clouds, your latitude, local light pollution and the timing of the event determine whether the sky is actually visible. The comparison below focuses on features, forecast horizons, alert controls, data depth and practical viewing tools—not a claim that one app is objectively more accurate.

What an aurora app can—and cannot—tell you
Aurora apps combine model output, solar-wind measurements and location settings into a notification or map. The most widely used model in these listings is NOAA/NWS Space Weather Prediction Center’s OVATION product. Its map shows the predicted intensity and location of the aurora for the time displayed. SWPC also publishes a separate 30-minute aurora forecast.
That wording matters: a map is a prediction for a specified time, not a visibility guarantee. A bright model oval can pass over a location covered by cloud, occur before astronomical darkness, or be too low on the horizon to see from a particular site. Treat an alert as a prompt to check the sky and local conditions, not as proof that the aurora is visible.
#1 Best Overall
Three time scales you will encounter
- Immediate guidance: A 30-minute map is useful when you are already outside or can reach a dark site quickly.
- Short-range planning: One- to three-day information can help you decide whether to keep an evening free, while still changing as new solar-wind data arrives.
- Long-range outlooks: A 27-day or several-week view is for planning and pattern awareness, not a dependable appointment calendar.
Cloud cover and darkness are not replaced by any of these time scales. Check a conventional local weather forecast, sunset and moon conditions, and the actual horizon at your chosen location before driving.

My Aurora Forecast & Alerts: simplest free starting point
This app is aimed at someone who wants to know when activity is expected to be high without learning every solar-weather parameter first. Its US App Store description advertises free push notifications for high activity, a map based on the SWPC OVATION forecast, current Kp and local likelihood, several forecast horizons, solar-wind statistics, solar imagery and webcams.
Free tools Windows power users keep installed
One-click scans. No signup required.
What you can do with it
- Enable a push notification when the app expects high auroral activity.
- Open the OVATION-based map to inspect the predicted oval rather than relying only on a phone notification.
- Move between near-term and several-week outlooks when deciding whether to plan a trip.
- Use solar-wind statistics and imagery when you want context for why activity may be changing.
- Check webcams for a quick indication of conditions at remote locations.
The listing also mentions tour information and destination recommendations for Iceland, Sweden, Finland, Alaska and Canada. Treat those as in-app travel information, not as a guarantee that a particular destination will have clear skies or visible aurora.
Trade-offs
The cited listing is the US App Store version. It says the app’s functionality is free but ad-supported. Android features, country availability and current behavior may differ, so check the store page for your device and region before relying on a particular control.
Aurora Forecast & Alerts: the most configurable short-range view
This listing focuses on people who want to set their own Kp alert threshold and inspect a chosen spot. It advertises a 30-minute map that provides a spot-specific aurora visibility forecast, plus a 30-minute geomagnetic-power forecast. The map data is described as customizable and updating every five minutes.
Forecast material and controls
- Kp push notifications: Set the activity level at which you want to be notified instead of accepting a single universal trigger.
- Location detail: Select a viewing spot to see the app’s short-range visibility estimate for that place.
- Supporting data: Inspect solar-wind parameters and geomagnetic information alongside the map.
- Planning horizons: Use the advertised three-day and 27-day forecast material for different planning windows.
- Official notices: The listing includes SWPC alerts and warnings as another stream of information.
Some graphics are explicitly labeled experimental in the listing. Read those displays as an additional visualization, not as a validated promise of what your eyes will see. A five-minute data refresh can make the interface feel current, but it does not remove the uncertainty in the underlying forecast.

Aurora Forecast is built for a reader who wants more than a single alert. Its listing advertises live community sightings, an NOAA OVATION model, real-time solar-wind and geomagnetic activity, an interactive aurora probability map, a 3D globe and multi-day Kp charts.
Features that help on location
- Community sightings: Reports from other users can indicate that someone has recently seen activity, but they are observations from particular places and times, not a forecast for your location.
- Webcams: Remote camera views can help you check whether a site is dark or cloudy before traveling.
- Dark-sky location finder: Use it to identify places with less artificial light; confirm access, safety, weather and opening hours separately.
- 3D globe and probability map: These provide geographic context for the predicted oval and your position.
- Apple Watch app: The listing advertises a wearable option for notifications.
- Storm notifications: Alerts can be customized around stronger activity.
Pro and Ultimate subscriptions are listed with monthly and yearly billing. The available description does not establish current amounts, what each tier includes in every region, or whether all features are available on every platform. Check the live store screen before subscribing.
SpaceWeatherLive: alerts with more solar context
SpaceWeatherLive describes itself as a near-live resource covering space weather from the Sun to Earth. Its app page advertises automated alerts and written reports by a team during periods of high solar or auroral activity.
This approach suits readers who want to understand the event behind an alert: a report can add context that a simple “go outside” notification lacks. It is less clearly positioned in the available description as a location-first viewing planner with a dark-sky finder or community sighting layer. No evidence in the available product information establishes that its alerts are more accurate or faster than those from the other services.

“Just tell me when it may be worth looking”
Start with My Aurora Forecast & Alerts if you prefer a free, ad-supported app with high-activity push notifications, an OVATION map and basic supporting data. Keep a local weather app and a dark-sky plan alongside it.
“Let me decide the alert threshold”
Choose Aurora Forecast & Alerts if a configurable Kp notification and a spot-specific 30-minute map are central to your decision. Its experimental labels mean you should use the display as guidance and verify conditions independently.
“I want reports from people who are outside”
Aurora Forecast is the natural fit when community sightings, webcams, a dark-sky finder and an Apple Watch notification are more useful to you than a minimal alert screen. Confirm that the subscription tier you need is available in your country.
“Explain the solar event, not just the chance of lights”
SpaceWeatherLive is designed for near-live space-weather information, automated alerts and written reports. It can complement a viewing-focused app if you want narrative context around changing conditions.

Set up alerts without creating notification noise
- Allow notifications only after choosing a purpose. Decide whether you want a high-activity warning, a Kp threshold, storm notifications or official space-weather notices.
- Set your viewing location. Use the place where you will actually stand, not merely your nearest large city. A regional forecast can look favorable while the horizon at your site is blocked.
- Pick a threshold you will act on. A low threshold may produce many notifications that are not useful from your latitude; a high threshold may notify you only after the best opportunity has passed. Adjust it after observing how often alerts lead to conditions you can check.
- Keep short-range and long-range views separate. Use a 27-day or several-week outlook for planning, then switch to the 30-minute or same-night map before leaving home.
- Check the map time stamp. OVATION colors refer to the time displayed at the top of the map. Make sure you are not interpreting a past or future frame as current conditions.
- Confirm sky conditions. Check cloud cover, darkness, moon brightness, local light pollution and road or site access before traveling.
- Use a second signal when the decision matters. A webcam, community sighting or written space-weather report can add context, but none replaces an unobstructed, dark sky at your location.
How to interpret Kp and local-likelihood displays
Kp is a broad geomagnetic-activity index, so a Kp alert is not the same thing as “the aurora is visible from my backyard.” Your latitude, viewing direction and darkness still determine the practical result. An app may show current Kp, a predicted Kp chart, a local-likelihood estimate or a model oval; read the label so you know which kind of information you are using.
A high value on a multi-day chart can identify a period worth watching, while a spot-specific 30-minute estimate is more useful for deciding whether to step outside now. These displays can disagree because they represent different time windows and inputs. Do not average them into a made-up probability.
Common failure modes and fixes
The alert arrived, but nothing was visible
Check cloud cover, daylight, haze, light pollution and the direction of the unobstructed horizon. The alert may have described predicted activity overhead or farther poleward than your exact site. Wait for the forecast window to advance before concluding that the event has failed.
No alert arrived
- Review the app’s notification permission and phone-level battery restrictions.
- Confirm that the selected location and threshold are still saved.
- Check whether the app requires background activity or a subscription for a particular alert type.
- Open the app manually; a data connection or operating-system delay can prevent a push message from appearing on time.
The map looks different from the sky
Verify the map’s displayed time, your map position and the forecast horizon. A model intensity map is not a photograph of the aurora, and local clouds or terrain can hide activity represented on the screen.
A store listing promises a feature I cannot find
App-store descriptions can vary by country, platform and software version. Recheck the current listing, update the app and look at the subscription screen before assuming a feature is included. This is especially important for the paid Pro and Ultimate tiers and for Apple Watch support.
Cost, platform and privacy checks before installing
Prices and feature gates are volatile. My Aurora Forecast & Alerts is described as free with advertising in the US App Store listing. Aurora Forecast lists paid Pro and Ultimate monthly and yearly tiers, but current amounts were not established here. The other descriptions do not provide a complete, region-neutral price comparison.
Before enabling alerts, verify the exact app name and developer in your device’s official store, supported operating system, notification behavior, advertising or subscription status and whether location access can be limited to the settings you are comfortable with. Do not assume that an iOS feature, an Android feature or a US listing applies unchanged elsewhere.
Bottom line: pick the alert style you will actually use
There is no evidence here for a universal “most accurate” aurora app. Pick My Aurora Forecast & Alerts for a simple free high-activity notification and broad set of viewing information; Aurora Forecast & Alerts for adjustable thresholds and a frequently refreshed, spot-specific short-range map; Aurora Forecast for community sightings, webcams, dark-sky discovery and wearable alerts; or SpaceWeatherLive for near-live solar context and written reports. Whichever you install, treat the notification as an invitation to check the real sky—not as a promise that the aurora will be visible.
