I dont get impressed easily now, but I loved this Heart Rate Monitor, and Its much more than a heart rate monitor! Let me explain. First of all, I needed an app that I could use for biofeedback to prevent my migraine headaches. The normal duration of the exercise here is 5 minutes long. Simply a Must have if you are in search of the very best in heart rate monitors along with crystal clear graphs showing both your heart rate and breathing in target and oscillation of your heart rate. Anyone health-conscious should have this app! Job well done...
