And you can print out 1:25K and/or 1:50K maps of your route to take with you.
The "leisure maps" don't work on my phone, though, which is tedious. The app allows me to log in but as soon as I try to look at the 1:25K or 1:50K mapping it hangs, even with maps downloaded on to the phone. I had a longish to-and-fro about the problem with the OS and they ended up telling me that my phone was too old to run the app - which was b*ll*cks because it ran perfectly fine on another, older phone running an earlier version of Android. I'd have been less annoyed if they'd simply said they couldn't/couldn't be bothered to fix it.
