Coton includes:
- 33 cloud index cards for the main cloud genera, species, varieties and special clouds
- a gallery containing more than 120 awesome pictures
- an illustrated guide which simply explains what is a cloud and how clouds are classified
- a chart of the 10 cloud genera
- a setting allowing you to switch between metric and imperial measurement system

The only thing you'll have to do is looking up... Enjoy your spottings!
Just remember: "It is rare that a cloud gets the shape of a cloud." Ylipe

I’ve loved this app forever...

But because it’s been around for so long, they really need to update their images. The beautiful images look so low quality on current screens. Still, useful and I adore it.

Just what I was looking for!

I want neither a committee nor a ‘social network’ to view, amplify, or grade my cloud names! I have no reason to ‘log in’ either: I just want to learn about clouds, why they create the shapes they do, when they occur, what do the weather-folks call them? This App does exactly that for the whole family! Concise, clear, photos are easy to view, even though some of those clouds do look the same to me. Haven’t had this but a couple weeks and have referred to it several times, no hesitating nor crashing nor sudden closing on my (iPhone 6. Really do like this App. Thanks!

Lovingly crafted reference guide

It’s great the developer continues to support the app some seven years after releasing it.

Not much to it: clouds and selected weather phenomena, pictures and brief descriptions. At a basic level, I wouldn’t change a thing. It’s accessible and utilitarian.

If I were to nitpick however: It could use a little proofreading in the descriptions, but from what I understand, English is not the developer’s first language, nbd. Metric conversions would be nice for us savages that still use feet and fahrenheit. Also, common iOS gestures such as swiping left edge to right to go back and a downward swipe to exit a picture aren’t supported. On notched iPhones, the back button is partially obscured and not in the display’s safe zone per Apple’s Human Interface Guidelines.

Otherwise, it’s a great app, honest in function, with a no nonsense pay-once price.
