Locatorz takes ramblers-favourite Ordnance Survey maps and turns them into slightly ominous people-tracking tools.
Locatorz uses Ordnance Survey maps, so your pizza-delivery guy's boss can see whether he's stuck on a cattle grid or taking a detour around the Roman ruins.
The company says that for people such as taxi drivers, who have to visit dodgy locations where their safety could be at risk, being able to track them makes them safer.
It also suggests that tracking your kids within 10m gives them freedom while soothing your Daily Mail-fuelled panic -- although knowing your parents are ogling your choice of public footpath isn't our idea of freedom. 'Elderly
parents or relatives' are also suggested
The service costs £57.50 per year from Locatorz' Web site and you can install it on as many mobiles as you can morally and legally get your hands on.
