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!

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.

Very well done

This new update works without a problem, bug free. Nice app with good descriptions of cloud types. Landscape mode not included but would benefit iPad users. Good job!

Not enough education

Even in this app they have a actually picture of a Plane Contrails. They dissipate the Ice When the sun is out. Gov/CIA already admitted they spray toxins they change name to aerosols atmosphere injections if you don’t cover it then I think it is a CIA app
