About this app

Discover the amazing world of clouds with your pocket guide to the wonders of the sky and have your spottings verified as you build a collection of clouds.

Learn what makes each formation special with expert text from the Cloud Appreciation Society and stunning reference photographs by our app users around the world.

Build up your own Collection of spottings and use our innovative tools to find out what type of clouds or optical effects you’ve spotted. See New Spottings by other users around the world and say (with our help) if you think they got the clouds right. Our uniquely trained CloudSpotter AI can analyse your image and tell you what cloud types it thinks you’ve spotted. Or you can answer questions about the sky in our Step-by-step Wizard to find the most likely formations. Becoming an expert cloudspotter has never been easier or more fun!

And if you’re a subscribing member of the Cloud Appreciation Society you’ll be able to access our Cloud-a-Days each morning. These feature curated photographs by our members, explanations of the clouds featured, inspiring sky quotations, and even examples of clouds depicted in art.

Looking up will never be the same again!

Ratings and reviews

Only my first spotting is listed in my collection. Every time I spot a new one it says cloud spotted but never saves it. I really want to like this app, I think it has the potential to be awesome. My suggestions: -Fix spottings -Add camera controls like zoom within the app -Make it interactive between users so you can see other people's spottings, where it was, comment, and help identify (like on iNaturalist)

Good app but innacurate: stating nimbostratus is able to produce heavy precipitation is false, cumulus and cumulonimbus are the only clouds capable of producing heavy precipitation, especially isolated and scattered.

A really excellent cloud identification app. The best I have seen so far. Not only are the common clouds pictured and discussed but also the more rare which aren't on other apps. First rate app.
