iheart offers better resolution (20 bits) and higher sampling speed (200 sps) than any other commercially available oximeter.

The iheart device is the only fingertip oximeter precise enough to measure pulse wave velocity and determine aortic stiffness. iheart also provides valuable insights into brain and autonomic nervous system health using the iheart Brain and iheart HRV apps.

Heart health data you can count on 

1. Backed by the latest research. iheart measures Aortic Pulse Wave Velocity (AoPWV) to determine your level of aortic stiffness, a scientifically-proven marker of heart health and measure of wellness.

2. Superior performance. The iheart device has the highest sampling rate in a consumer oximeter, providing the unique measure aortic PWV.

3. Assess Autonomic Nervous System Health. iheart Brain and iheart HRV provide a novel way to assess strength and balance of the autonomic nervous system.

4. Track blood pressure changes. iheart is able to track changes in blood pressure that occur when standing up from a sitting position to assess Autonomic Nervous System and brain function.

Aortic PWV is used to determine Aortic Stiffness. Aortic Stiffness is strongly associated with heart health and is also an indicator of overall wellness. iheart performs analysis of the arterial pulse signal to determine Aortic Stiffness and calculate Internal Age.

5. Used by healthcare practitioners. The iheart device complements conversations with your wellness practitioner and provides accurate, convenient wellness monitoring.
