IMHO, the best presentation of critical weather and seeing conditions for astronomy and astrophotography.

This app has been a lifesaver with planning astrophotography sessions and finding new locations to set up.

This is my goto app for cloud cover for my astrophotography hobby. It's pretty accurate, and it's the best 99 cents I spend each month!

Love the app! It got me to clear skies for totality today! 2024 Great American Eclipse. Diamond Ring, Baily's Beads, and Corona wall art coming soon thanks to Astropheric! Tried to find & tag you on Instagram, but you don't seem to have a presence there.

This is one of the most useless apps I've ever used. It is often comically inaccurate. At the time of writing this review, the app says there is 8% cloud cover, but looking at the sky, it is very nearly 100%. This is not at all unusual. I'm not sure what the app developer thinks they're gaining by making the forecasts WAY too optimistic all the time...?
★☆☆☆☆Robert King· Aug 20, 2025
Just not accurate. App says no clouds and there's nothing but clouds.

I paid for this app before the 2017 eclipse. I didn't end up using it in Wyoming during the eclipse, since it was only 148 seconds, but it would have been nice to explore the app some later. Now, for the 2024 Mexico-USA eclipse, I opened the app only to discover that it is simply a huge advertisement, leading to a website, with Z E R O total solar eclipse information. What a joke abs a waste of money!

Not accurate (cloud cover) at all. It says 0%, and I'm outside looking at 90% cloud cover. Not helpful for planning astrophotography.
