Wild Review: ViewRanger for iPhone

"The thought of having all these maps available on my phone and in my pocket makes me positively giddy.  The app features many of the same functions found on GPS devices: create routes, mark waypoints and points-of-interest, set up alarms to warn if you stray too far from your intended route and so on." The more you use it, the more adept you become [at using the app] and after creating a few practise routes and marking some POIs I started to hum along."

Four and a half stars out of five.
