yourPulse... Every second your heart beats at a set rate. If you exercise that rate should increase to an elevated rate. thePulse lets you find your heart rate and keep track of what your heart rate is at different conditions. Say you are just resting, take your heart rate. Go for a run and then take your heart rate. The next time you run, take your heart rate and compare to see if you did as much work. thePulse will give you your maximum heart rate (based on your age) and then will give you your target rates for your fitness level.
