Using your smartphone for detailed maps is great when you are traveling with access to a cellular connection, but when you're off the beaten path, they are pretty much useless. For those times, an app called Anchor Pointer for iPhone can be a real help. Because the GPS in your smartphone works without a cellular connection, the app can turn your iPhone into a pretty decent compass. The app allows you to create 'anchors', which are essentially waypoints for navigating using the GPS. For example, if you are taking a hike, create an anchor point wherever you park your car or if you are exploring a remote area, you can create anchors where you are staying overnight. Making use of GPS coordinates allows the app to provide both direction and distance to all of your anchors without the need to reference a map. If you are traveling in a group, the 'meet a friend' option allows you to coordinate gatherings or meetups. The Anchor Pointer app will run you $1.99 and is available in the AppStore http://pleeq.com/anchor-pointer
