I've never heard of that one. Good for him!
I'm glad my iPad has both camera front and back. It is nice. BTW, there is an app called Yarma that is set up for Ravelry. I don't know if it's only for Apple products, but it's worth a look.
Eta: I searched and was able to find an app for android phones. It's called Ravelry Photo Uploader. It supposed to work on tablets and android phones.
