Hello Tony, I developed an app for my beginner students recently at their request and since I'm a mobile software developer, I released it for iPhone/iPad and Android. It has the Taekwondo curriculum I teach at my two academies. The iPhone/iPad can be downloaded freely and you can read the "theory" course and glossary for free as well. Other courses can be accessed through in-by tamaro - New to taekwondo? This is the place for you!
