DeepHeart Technology™

How To Use

Just take one HR measurement per day, and rthm will automatically analyze your heart health trends over time. The app detects your heart rate by measuring the subtle vibrations each time your heart beats. This is a proprietary, patent pending technology unique to Rthm.

Resting Heart Rate

Resting Heart Rate is one of the most reliable indicators of overall health, with lower resting heart rates associated with longer lifespans. Take your Heart Rate in the morning when you wake up, before coffee, to get a reliable measure you can track over time.

DeepHeart Score

Built on years of research, and over 1.8 million unique recordings, DeepHeart is the world's first technology to instantly analyze your cardiac health using only the sensors built into your iPhone. DeepHeart analysis should be done each morning, right when you wake up, to reduce the effect of confounding factors. A higher score indicates higher cardiovascular health and reduced inflammation.

Stress Score

Your nervous system is governed by two branches- the sympathetic and parasympathetic. By analyzing subtle cardiac patterns, scientists can see if either are overactive, which can lead to burn out, common colds, and more. Your Nervous System Score is calculated using the same method scientists have employed for decades- but with our algorithms you don't need them or their equipment, just your iPhone. A higher score means lower stress.
