Colours app for iPad and iPhone

Came across this blog article today and love the idea of this app! http://www.appsplayground.com/apps/2012/10/09/color-hunt-for-kids-iphone/#more-2853

I then found and downloaded the free app Find!Color which works on similar principles but has turned it into a game with points. I can see how both would be useful - non competitive (color hunt), finding colours against a set time limit - good for teamwork and excitement (Find!Color)

Both apps are listed for iPhone but the demo video shows the app being used on an iPad and I had no issues using Find!Color on the iPad.

Would be interested to see what other people also think!
