The ease of use for both patients & providers alike! It is so easy to navigate through the software that you can easily find what information your looking or where it may be located in another system/software program as well!! I love everything about this product. There's nothing i dislike at all either. ! This has been one our best products we have purchased since becoming an EMR provider 10 years ago. !! We are able to provide better care with less time spent searching databases / finding info etc...... SpellBound is a great tool for patient education. I have loved every lesson I have taken. I love that I can take my own pictures and add them to the lessons. I also love that I can make the lessons interactive. I think the lessons could be improved by having more videos, and a better way to add questions and answers. I love that I can use the app on my phone. I don't have to print anything. I can take the lessons on the go. I can give lessons to my patients who are not able to come to my office.
