This app does exactly what it says perfectly. In fact its the most intuitive route plotter i've found but I need 'one more thing' to make it beyond perfect! While Tom Toms & Garmins are okay for point to point directions fI find them messy to plot routes with.
I do a lot of walking in cities and I'd like to be able to plot a route of the special places I'd like to visit without constantly looking at the iphone. Just simply plot the route then listen to the turn by turn prompts. This would save time and you could focus on the sights.
