[pct-l] Downloading Halfmile Maps on Phone

[Kathi]

Hey All,
I often see mention here of downloading Halfmile's maps to iPhones, etc. 
I spent a bit of time last night trying to figure out how to do that and 
couldn't. I clicked a bunch of links on his site that I thought would, 
but they didn't or I don't know where they went. I have the app and 
couldn't see how to do it in the app. I've got an iPhone 6. Help please!
Thank you!
