Comments on Astrospheric for Android

★★★★★ jchester316 · Apr 15, 2024

This is a fantastic app with incredibly powerful tools available and great, informative views to help a weather wonk or enthusiast make sense of the various model outputs. This app single-handedly halped inform and save my eclipse viewing experience. It was spot on.

★★★★★ hurdpcs · Jan 17, 2026

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!

★☆☆☆☆ Jason Adamik · Apr 5, 2024

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!

★☆☆☆☆ jkd · Apr 9, 2026

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

★☆☆☆☆ Robert King · Aug 20, 2025

Just not accurate. App says no clouds and there's nothing but clouds.

★☆☆☆☆ Alan Marvin · Jan 27, 2024

Tried to use to plan astrophotography but the cloud cover is not close. Tonight it says 2% cloud cover but actually is 75%
