This app isn't bad, but it could be better. It has a lot of content, which is good, but the functionality is lacking. The pattern list, for example, just has photos & names. No indication of skill level, no way to sort the list, etc. I did find a separate list of the patterns organized by skill level, but it wasn't linked to the patterns -- it was just a text list. Not so helpful. What REALLY annoyed me and ultimately drove me to delete the app was the audio. Why announce each section as I click on it?? I didn't see a way to turn that off, and I didn't want to mute my iPad each time I used the app, so it's gone.
