Good fun for young and old but a bit touchy.

Overall, its a pretty cool app. I love how you can import your own photos and then trace or draw over them to create a new trace rendition of your picture. The only thing I found was that my 3 yr old had a lot of trouble selecting functions and colors. She would have to tap on it over and over to finally have it register. I had less of this issue but it happened to me too. Still good fun when you or your kids are feeling creative.
