Northern Lights forecasts, the KP index and aurora alerts, now on the Duo
Does My Aurora Forecast & Alerts work on iPhone Duo?
Yes, since version 26.8.1 on October 19, 2026, says its developer: it supports every orientation and pose on the cover and the open display. The release notes don't describe the layouts.
- App Store confirmedJake Ruston of jRustonApps, the developer, in a submission to FoldHunt on October 20, 2026 that covered all the studio's apps, ticking the closed, open, half-folded, stand and Split View poses and saying: "Full support for all orientations and poses in the inner and outer screen." The App Store seller is JRustonApps B.V. The release notes for version 26.8.1 (released October 19, 2026) say: "The design of the app has been improved. iPhone Duo support." My Aurora Forecast Pro (version 26.8.2, released October 21, 2026) has the same notes.

About My Aurora Forecast & Alerts
My Aurora Forecast tells you how likely you are to see the Northern Lights, in the United States or anywhere else, with the current KP index, a list of the best places to watch from right now, a world map of the aurora’s strength from the SWPC ovation forecast, solar wind details and high-resolution images of the sun. Push notifications are free. It has a dark design for watching at night.
Version 26.8.1, out on October 19, 2026, adds iPhone Duo support along with a redesign, its release notes say. The paid edition, My Aurora Forecast Pro ($3.99), got the same update. Jake Ruston says the apps support every orientation and pose on both the cover and the open display, without describing the layouts.
