I have a few quilting aps on my iPad. My favorite is quilting 101. It is a reader for video feeds from Leah Day on FMQ. She usually updates twice a week with a new tutorial video. Very inexpensive and fun to watch. I also use the block one mentioned earlier for inspiration. I have not tried the $30 one but would be interested in knowing about it if someone does decide to get it. The quilting 101 is under iPhone apps.
