Publisher's description - PulseRatePro 1.0.1
PulseRatePro lets you measure your pulse before, during and after exercise and see it graphed as you work out using the camera and flash on your iPhone 4. You can save and refer back to your old pulse measurements to measure your progress over time.
Your target heart rate is calculated by your age and sex and can be displayed on your the graph as you work out along with your target zones.
Place your finger firmly over both the camera and flash for an accurate measurement. Changing the position of your finger will force PulseRatePro to recalibrate.
