For every mile walked with the Comeback App, Zimmer will donate $1 to the Arthritis Foundation. The Zimmer Comeback App uses the GPS in your phone to track the miles and route you walk. Users can share their route map and walk photos on Facebook. A leaderboard will display the users that donate the most miles on the Zimmer Facebook page. Zimmer Comeback can be used when walking or running.
