Heart Monitor: An Amazing New Application For iPhone

This post is also featured on Reuters and Livestrong.com

AS A PERSONAL TRAINER, I BELIEVE IN monitoring your heart rate, and knowing your resting heart rate is one key indicator of physical fitness. So I was thrilled to discover Heart Monitor, a new application for the iPhone 3G that uses the phone’s built-in microphone to detect your heart rate. Just hold the iPhone to your chest or directly on the pulse in your wrist or neck. The application tracks results so you can see your progress over time. It even works with the phone’s microphone cable. This is just one more example of how the iPhone has trumped the Blackberry and Treo as more than a phone. It’s a tool for living. —S. Page
