How about this for a fun app to put on your phone? “Relive” tracks your walk, cycle or run by GPS. At key points on the way, you take photographs on your phone. At the end it gives you a fly-through of your route, including background scenery. The clever bit is that it also shows you your photographs at the point on the route at which you took them. You can send this record of your walk to your friends and really impress them! Have a look at their website and then you can download the app onto either android or Apple phones.
