Aurora notification app with observation reports. Finally available for iOS. This aurora notification app shows notifications when it may be possible to see the northern lights (aurora borealis / australis)! It provides configurable thresholds for local aurora probability, Kp-index (Hp30), solar wind parameters (Bz/Bt) and Kp-level forecast for the evening. It also allows you to be alerted when other app users nearby have seen the aurora light display. For the alert feature to work, other app users register aurora reports when they are successful hunting and get to see the aurora light display. This has proven to be quite successful. Many of the app users also upload pictures of northern lights when they see them, and in this app you can see these pictures. You can also see dots on a 3d-globe animation showing where people have just observed the light show. There are users in the US, Canada, Europe, Australia and New Zealand who regularly report their observations and upload pictures. Although the chances are greater if you live in Alaska, northern Canada, Norway, Sweden, Finland, the southern tip of New Zealand etc, there are also regular opportunities in places like Minnesota, Wisconsin, Washington, Montana, Michigan, Chicago, New York, Scotland, Denmark, Germany, the United Kingdom, France, the Baltics etc. The premium version which can be bought within the app itself offers some more technical information and graphs of Kp-index predictions, cloud cover and solar wind parameters - and some hidden features. The app has an associated X account (@aurora_notifier - https://x.com/aurora_notifier) and an Instagram account (@auroranotifierapp - https://www.instagram.com/auroranotifierapp). Consider following those.

Verdict
The clearest difference is in-app purchases: Sunspot Oslo at none against Aurora Notifier's 2. Aurora Notifier's advantage is update cadence (every 5 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
