A clever addition to the Android Market just in time for Get Walking Day… free Walking Paths app enables users to find, tag and “like” more than 2,500 American Heart Association-designated walking paths across the country, or even create and save favorite walking paths using the GPS function as they walk. The app is available now for GPS-enabled Android smartphones ā in time for the fifth annual National Start! Walking Day on April 6, when the American Heart Association calls on all Americans to find 30 minutes in their day to walk to improve their heart health. The app will be available for iPhone and iPad users via iTunes on May 1.
