nancysp....there is an iPad app for Craftsy. I have taken several classes. Craftsy is the best thing since sliced bread!! You can access it any time, as often as you want. If you have questions you can ask the instructor and you will get a response in 1-2 days. I have not taken Angela Waters. I'm taking Leah Day now. I have taken Wendy Butler Burns on machine quilting. I have two from Jenny Doan on Quilting Quickly. They frequently have sales and I just watch for them.
