HeartWorks

HeartWorks is an application for the iPhone that monitors your heart rate. It works with heart chest strap and watch monitors that use the Bluetooth Smart.

It is designed to work for many hours and save all your heart rate data into a zoomable graph. You may have many sessions, keep them and view their statistics and graphs later.
It works in the background and the heart rate is even displayed as a number in the app icon.

HeartWorks does not claim to be, nor intends to be, a medical or clinical application.

Basically, HeartWorks monitors your heart rate and saves the data. The iPhone needs to be connected to a Bluetooth heart rate monitor (such as a Polar or Wahoo).
