My recently-purchased smartphone came with a whole series of features that I don't want, but one has raised my interest. It basically counts paces when you are walking, thanks to its in-built movement detector, and thereby calculates how far you've walked. The app sets a period of activity and a distance to walk as targets and congratulates you if and when you reach them, although it also scolds you and tells you can do better if not. It is no use trying to explain that you went out for a walk without your mobile or you have to sit down and write an editorial!
