Heartbeat is an app that can locate the closest AED, Automatic External Difibulator, to a bystanders location. In the event of a cardiac arrest, the victim needs an AED within 10 minutes to revive him/herself. Because the average emergency response time is 8 minutes the chances of survival are low. The app that Jordan Schmidt and I created solves this problem by locating and giving a route to the closest AED to the bystander.
