Leverage real-time health insights

iheart has the highest resolution (18 bits) and sampling rate (200 sps) available in commercial pulse oximeters.

Our precision data allows us to derive Aortic Pulse Wave Veloocity (AoPWV), and measure autonomic nervous system response.

    “iHeart Internal Age has been a vital part of my life! I started using it to enhance my fitness and track stress. At first, I was horrified to see how old I was on the inside. After using it for a while I caught a severe case of pneumonia and the iHeart internal device basically lived on my finger to monitor my oxygen levels. I am now proud to say my internal age matches my physical/external age. ”

    “It encourages you to figure out a way to get healthier. I rarely go to my doctor unless something's really wrong, and if you're not getting feedback regularly, you don't usually change anything. I think for me having that reminder every day is really helpful.”

The world's firsts accessible measure of Pulse Wave Velocity (PWV)

Traditional carotid-femoral Aortic Pulse Wave Velocity (PWV) tests cost upwards of $25,000 to perform and require a skilled technician to operate. 

For most physicians, that kind of tech is out of reach. Until now. 

iheart's unparalleled accuracy allows us to measure Aortic PWV in just a couple of minutes. Finally, practitioners can offer this valuable health metric to their patients anytime, anywhere.
