An App A Day To Keep The Doctor Away

You can now use an app to summon a GP to your home, in the same way you would order a takeaway. We have come a long way since 1977, when a cardiologist named George Diamond pitched the idea of a primitive health app to predict heart disease to Steve Jobs. Jobs turned it down. Scroll forward to 2016 and there is a burgeoning field of what’s known as mHealth, medicine and public health supported by mobile devices. There are more than 165,000 mHealth apps in a market worth $489m (£346m).
