What's New in Solar Alert

5.0.0

October 23, 2026

Solar Alert 5.0 — the biggest update in its history. Space weather, explained. THE APP NOW EXPLAINS ITSELF • Tap the help button on any screen and Solar Alert tells you what you are looking at. More than 900 explanations across 17 screens, in five languages, at two levels: a quick line answering “what is this”, and the full scientific context if you want to go deeper. Includes a tutorial mode that walks you through each screen step by step. YOUR ALERTS, ALWAYS AT HAND • A new screen keeps the last fifty alerts you have received, each with its image or animation you can enlarge. And tapping a notification takes you straight to that event, with no steps in between. DISCOVER PREMIUM FOR 30 MINUTES • If you are on the free version, you can open the Premium content for half an hour, once. No payment, no details to hand over and nothing to cancel afterwards. DATA, EVEN IF A SOURCE GOES DOWN • We have improved the redundant solar data system: if one source is slow or unavailable, your forecast still arrives by another route. Information loads considerably faster and the scientific panels refresh on their own every minute, with no flicker. A FORECAST THAT FITS YOU • It adjusts to your latitude, and now works without GPS too: type in your city or pick your band of the planet. Your location is used only to adjust the forecast on your device; we do not share it with third parties. THE SUN, CLOSER • The Sun view opens straight into the first image. Move through the 42 observation channels by sliding along a strip of thumbnails, all with native zoom. The OVATION aurora map goes full screen and the photo gallery flies. BETTER ALERTS • They arrive in five languages — English, Spanish, French, Italian and German — and solar flares now notify you both when they begin and when they end. FASTER START, NEW LOOK • The app starts noticeably sooner and, when you come back, you find it where you left it. We have redesigned the background images that show the state of space weather, with a special display mode for anyone who needs to read more comfortably. NEW VIDEO AND CATALOG • A new video shows what really happens during an extreme solar event: in your home, in your city and to the services you depend on. And you now choose which documentary to watch from a catalog. 14 YEARS BEHIND EVERY ALERT • Solar Alert has been on the App Store since 2012, with a 4.7 average rating. Behind it there is more than an app: a team, our own server and data from official observatories and agencies, running every single day. Cloning a few good-looking screens is easy today; keeping an alert system you can trust running for fourteen years is not. STRONGER ON THE INSIDE • We have fixed many small issues and strengthened stability across the app. A good part of those fixes came from the messages in which you tell us what you were doing when something did not go right: it is the best diagnostic tool we have. We have also brought the oldest part of the code up to date, to leave the app ready for the coming versions of iOS. When the next strong storm arrives, you will want to be warned. You will want to understand what it means. And you will want the app that tells you to be up to it.

User reviews

Pretty good

Over all, I do like this app. There are a lot of features you can interact with. It’s informative and in recent updates, has functioned better.
My breakdown:
*The KP Forecast is probably the most accurate and on point, though I noticed there are times when it has about an hour or so lag. Usually during holidays or the weekend, where the NOAA website shows activity and the app hasn’t updated to show it quite yet.
*The Movie Solar Activity isn’t always up to date. It is currently, but I’ve noticed a lag that can sometimes be a day behind. However, if you go into the *Helioviewer, you can see all recent activity in that. Sometimes this glitches, but if you have good internet, it’s usually pretty good.
*The Aurora Ovation has rarely ever been accurate when I’ve used it. There have been auroras in my area that the ovation either doesn’t predict or predicts after it happens. Times when it says it will have, and it doesn’t. So for that, I defer to the NOAA Aurora 30 min forecast online.
*the Solar Plasma Ejection section is my favorite. The one that you click and it shows the solar blasts from the Sun and how soon they’ll reach Earth.
*I love the Home Screen of the app. It’s organized well.
*I also like the notification banners, but I wish that the notifications didn’t just disappear when I open the app, because I’ve yet to find a Notification Center where I can review the information. I’ve clicked on the *Protection System button (white circle) which seems to highlight and go off, but I don’t really see any new news or updates in there. And much of the official reports are few and far between, sometimes months old. *Occasionally, the Solar News Alerts have something more recent. But I do wish that there was an option to see the little notifications that come through within the app itself, because some are more detailed that in my banners, they don’t always show all the info and when I click the alert, it just goes away as it opens the app.
So over all, I like the app. But sometimes, the NOAA website is more up to date.

Response from developer

Hi real_mauian — thank you for such a thoughtful review. We’re really glad you find Solar Alert useful, and that you enjoy the home screen and the Solar Plasma feature. For 14 years, Solar Alert has been — and still is — the fastest solar-alert app on the market. If a forecast ever felt a bit behind NOAA, that can sometimes happen when the connection is slow or unstable — the app may briefly keep the last good data until a fresh update comes through. We’ve been working hard on a major update that further improves the performance of the forecast system, remote alerts, and the app itself. It also addresses several of the points you raised. You’ll notice the difference soon. Thanks again for taking the time to write this. Feedback like yours genuinely helps us keep improving. — The Solar Alert Team

Too Much For Me

Hello, Developer, and thank you for your kind response. I will certainly check back and update my review. All the best!

Original Review:

I really wanted to like this App, especially given all the great reviews. However, for me, the Graphics and Colors are disorganized and too intense. As well, I didn’t like the background images where the Alerts were. The images took away from the written information, as well as drawing your focus away from the icons at the top and even dulling one of the icons at the bottom that I initially thought was just a part of the graphics. Then the graphics with the huge Sun coming into focus, etc. I’m so sorry, but it was just too much for me. This App has a lot of great information. It just needs a huge UI cleanup. I would suggest that people try it out in spite of my review because it does have awesome information and some might not care about the UI/graphics/etc.

Response from developer

Thank you very much for sharing such detailed feedback, and especially for highlighting the quality of the information the app provides. We’ve taken your comments about the visual intensity, backgrounds, and clarity of certain interface elements very seriously. We’ve been working specifically on improvements in these areas to create a cleaner, clearer experience that keeps the focus on the information. These changes are part of an upcoming update that will be available very soon. Once it’s released, we’d love for you to give the app another try and hear what you think about the improvements. Thank you again for helping us improve Solar Alert!

Great tool for Fire, Police , emergency Management, weather forecasters and Preppers

Great tool for weather forecasters as well as emergency managers and preppers. The sun and the flares and solar storms can greatly affect fire, police and EMS radios, 800 mhz , short wave etc.
This app is worth every penny for the data and education offered through this app. Graphics are incredible as well. I’ve already referred many colleagues to this app. Keep up the good work.

Response from developer

Thank you so much, RaphaelLongview — we really appreciate your thoughtful review and your 5-star rating. It means a lot to hear that Solar Alert is useful for emergency managers, forecasters, and first responders. Solar activity can indeed disrupt radio communications — including 800 MHz systems and shortwave — and we’re glad the data, educational content, and graphics are helping you stay informed and prepared. Thank you also for recommending the app to your colleagues. That kind of trust from professionals in the field is the highest compliment we could receive. We’ll keep working to make Solar Alert even better. Stay safe out there.

Not free

Although not expensive $9.99/year basic plan, it’d be transparent to disclose in the App Store intro

Alertes non adapté

Je reçois des alertes la nuit alors que ma région n’est pas touché et je ne peut pas changer le dispositif de notification , c’est un logiciel pour les américains du nord

Response from developer

Bonjour, merci pour votre avis et pour avoir pris le temps de commenter. Nous souhaitons préciser que les alertes peuvent bien être adaptées aux préférences de chaque utilisateur. Dans l’application, il existe un réglage de seuil d’alerte qui permet de décider quel type d’événements recevoir et à partir de quelle intensité. Si vous souhaitez recevoir moins de notifications, vous pouvez facilement les ajuster dans cette section. Concernant les alertes reçues la nuit, les appareils Apple disposent d’options permettant de mettre les notifications en sourdine pendant la nuit, à l’exception de celles considérées comme critiques, comme celles liées à un événement solaire extrême. De cette manière, le système de notifications peut être configuré et adapté à vos besoins. À propos de l’idée que l’app serait uniquement destinée aux Nord-Américains, il est vrai qu’en Amérique du Nord il existe des cartes détaillées des réseaux électriques qui ne sont pas disponibles dans tous les pays. Cependant, toutes les autres fonctionnalités de l’application restent pleinement valables partout dans le monde. De plus, lorsqu’il peut y avoir des effets sur les infrastructures électriques, l’app envoie des alertes appropriées, en proposant des recommandations et des actions à suivre en fonction du type et de l’intensité de l’événement solaire, afin que l’utilisateur puisse agir de manière préventive avec le maximum d’informations possible. Lors de récents événements solaires, des aurores ont même été observées à des latitudes comme celle de la France, ce qui montre que ces phénomènes peuvent avoir des effets jusque dans les latitudes moyennes. En cas d’événement solaire extrême, des surcharges et des pannes pourraient survenir dans les réseaux électriques ainsi que dans d’autres systèmes électromécaniques (comme certains moyens de transport ou des infrastructures sensibles, telles que les centrales nucléaires). C’est pourquoi disposer d’informations en amont et de recommandations claires est particulièrement important, et c’est précisément l’objectif de l’application. L’application est conçue pour fournir une information utile et fiable à tout utilisateur, où qu’il vive. Nous vous invitons à vérifier vos réglages afin que les alertes s’adaptent au mieux à vos besoins et, si vous le souhaitez, à nous contacter depuis l’app elle-même pour que nous puissions vous aider avec la configuration.
