OZOM Track is the official free companion application to the Australia on the Move (http://ozom.org.au) wellness-focused social network.Like OZOM web, OZOM Track is all about making it easier for you to get active every day, wherever you might be. Use the walking/running and cycling track search to find great places to exercise in your local area, and then track your progress around them on a rich annotated map.If you're an OZOM Web member (free to all, and you can sign up from within OZOM Track), you can have OZOM track your run, walk, or ride on any of the given tracks, and log it to your OZOM account against your daily, weekly, or monthly activity goals. OZOM Track gives you handy real-time feedback as to how far you've moved, how long you've been moving, and how many minutes you've logged against your goals.Physical activity and being social go together perfectly, so OZOM Track lets you leave photos or comments on routes as you follow them, and shares them with other OZOM users who move on your routes.OZOM Track has been developed as a collaboration between Sports Medicine Australia (http://sma.org.au/), the University of Queensland (http://uq.edu.au), and Australian iOS developers Geeks of Bohemia (http://geeksofbohemia.com/)
