KesBT: Excellent
Great App, works well and you only need to buy the OS sections you need and not unwanted parts.
jdh: Great for hill walking in Scotland
This application has been very useful on both my iPad (for planning) and the actual hiking on my iPhone. A map purchase on either device syncs quickly to the other with no effort on the user's part. GPS with the iPhone tracks perfectly and the camera capture for waypoints is very convenient. Along with the ability to import tracks. Only item for improvement so far would be to enable a shopping cart for the map segments instead of making it all at once.
Matthias8383: Great app
