More than 40,000 applications are now available to smartphone consumers, many of them pitched at healthcare professionals and members of the public interested in their health and wellbeing.

All the evidence suggests that the medical app market can do nothing but grow. Whether it is delivering advice on improving your sleep patterns or a medical reference guide on some obscure syndrome, developers seem to have come up with an app for it.
