The iFootpath App does not use Ordnance Survey maps. Each walking guide has full directions, photos and most importantly a GPX track on the map. The GPX track shows the exact route the walk author took when creating the route and when you follow the guide you will see your location via a blue dot (make sure Location Services are on). Google and Apple maps are available at only a small yearly cost to iFootpath and therefore we have decided not to pass this costs on to the user. This helps us provide the iFootpath App and all the walks for a one-off fee.
Ordnance Survey maps are available via a number of Navigation Apps via a yearly subscription and you can, of course, use one of these navigation Apps the same time as the iFootpath App.
The following blog posts describe this a little further.
