## Most critical reviews (10 lowest-rated)

### 1/5 — Non-functional in iOS 26

*2025-09-29*

I’m going to guess that this is now nonfunctional in iOS 26 as all the images are now blank and black with a checkmark next to where the image should be.

### 1/5 — Same fail as the SOHO app

*2020-11-02*

It won’t open, it just crashes.   Please fix it.   Thanks

### 3/5 — Best to failure

*2021-10-06*

For years it was one of the apps I used first thing in the morning and before sleep.  Now, a week without any updates has soured my experience.  The SoHo app does nice, but doesn’t offer the variety of wavelengths.  I hope SDO gets fixed soon.

### 3/5 — Have problems on iPhone

*2020-01-04*

The images won’t download when I’m connected to the internet. Both WiFi and LTE.

### 5/5 — OkOk

*2020-11-05, version 1.4.1*

### 5/5 — Ne fonctionne plus depuis quelques jours

*2019-05-28, version 1.3.6*

### 5/5 — Astronomy

*2019-02-06*

This Is A Superb App For Viewing The Latest Images Of The Sun From The Solar Dynamics Observatory Spacecraft

### 5/5 — Bien

*2018-08-28, version 1.3.3*

Comme pour soho viewer.
Manque des courtes séquences vidéo avec les photos.
Ce serait plus vivant 
Bonne application et très utile

### 5/5 — Hmm

*2015-04-20*

Any reason why my 6th image has been black for a month?

### 5/5 — I like it! (but)

*2014-10-24*

This is a great addition to SoHo viewer. I know it's new, but you guys need a proofreader who knows their Continuum from their Magnetogram. I know picky picky.
