Anyone know an iPhone app that let's you build routes when you're out? Not Strava/Runkeeper style, but one that let's you add to it over time?
Reason I ask is I've just moved to Dursley (near Glos) where there are loads of trails in the woods behind my place but I keep getting lost. If I could take my phone up and mark different routes with different colours gradually a map of all trails will build up. I've read you can do this combining loads of GPX files, but didn't know if there's an app that just lets you build it over time?
