GraphBox is an iOS app providing useful tools for both learning graph theory and for solving graph theory problems. These tools help you to quickly produce detailed graph drawings and can be used to run various animated algorithms across those drawings.
Even though tablet computers are being used in many schools and there exists more than 20,000 educational iOS apps as of 2012, there is no educational software available to iOS to assist with learning graph theory, nor are there many adequate solutions outside of iOS. From my own experience, the way in which graph theory is taught in schools can be unnecessarily challenging. Often involving the practice of conducting algorithms by hand, this technique can prove frustrating and presents additional challenges to pupils with learning difficulties such as dyslexia.
