This week's All Things Appy takes a look at the five best, free geo-oriented apps for the iOS platform.
To keep your costs down, we're concentrating on those tracking apps that don't require additional hardware, like sensors.
Not all mobile Apple hardware products have GPS satellite location, which many of these apps require for best results. The iPod is one of those.
Also, be aware that GPS chips use an enormous amount of battery power, so expect to see degraded battery life the longer you run these apps.
GPS signals require a view of the sky. They don't work as well in dense cities or woodland.
About the iOS Platform: Apple's apps are available in the iTunes store. Browse to the store from your device's home screen and search for the app you need.
