Bill Harvey: On the road again

Bill Harvey considers how far self-monitoring health apps have come

After the shock of seeing the Queen playing We Will Rock You with Paddington, I switched over to catch the latest in the Beck Scandi-noir crime series. Hardly more relaxing, the plot involved the kidnap of a diabetic child whose father was able to see her gradually diminishing glucose levels over his iPhone using the Freestyle Libre system.
