Just what I was looking for I was just looking for a simple, easy to use app that predicted the likelihood of geomagnetic storms over the next 24 hours... and this does just that. I only wish it had a widget or a way to get notifications... maybe those will come in the next release... hint ;-)

Fantastic app Especially appreciate forecast info. I second the suggestion for a widget

Works great for me on my Pixel 4 XL. As an avid shortwave listener, I find this app indispensable.

It is ok Would be nice if you could make a widget that shows some useful info about solar flares, solar activity, or when next solar flare will hit earth.

Not as good as NASA. Not liking this you can't change to different cygnets. And very confusing to use.
★★☆☆☆Tony Cravatta· Mar 7, 2017
Looks good at first, but doesn't give any options to choose what data gets put on the home page, the videos for those sections are minimum two months out if dated, and several areas continually fail to load requested images.

Auto updates off. It did a stealth update today and was intercepted and deleted!
★☆☆☆☆Mohamed Nedal· Mar 14, 2016
CRASH! It doesn't show anything and it crash immediately after launch.
