Show HN: Yarnee for iOS

This is an App we worked on for many months, it was released to the public yesterday.

I was the technical project manager, what do you think about it?

BTW: You can give me simple feedback by shaking your iPhone very hard - then a screen shot will be captured and you can add a comment for me :-)

Looks very well designed. Unfortunately i don't have an iphone, but i like the idea of the "yarn".
