Accurate and aesthetic

Love all the data points this app graphs, plus allows me to tag what was going on during periods of abnormally high or low heart pulses. Resting heart rate also very helpful! Cool complications feature on Apple Watch too! Also offers capability to participate in a study with UCSF to learn even more about my heart rate.
