Hypertension affects more than 70 million adults in the United States, and even more individuals remain undiagnosed. Hypertension increases the risk of developing other serious health conditions, such as heart attacks, kidney damage, and stroke. Even though there are multiple devices on the market that enable people to track their blood pressure at home, consumer adoption of these self-monitoring devices has remained somewhat limited due to persistent deficits in design, portability, accuracy, and/or usability.
