Is this application worth $20? It is hard to say. If I was a professional in the health care system or a personal trainer I wouldnt hesitate to recommend this app. It is a great visual aid to show to your clients to give them a better idea of muscles you are referring to.
On the other hand students might find the $20 is too steep of a price to pay. An anatomy textbook is still far more detailed and more helpful. And you probably already own one. You may wish you spent your money going out with friends instead.
