About CardioOK
Improving hypertension control for everyone the health system leaves behind.
Our mission
To improve hypertension control in the United States — with particular strength for low-income patients and those with limited English proficiency — through continuous, multifactor follow-up: blood pressure measurement, medication adherence, and the nutrition, sleep, activity, and behavioral factors that determine whether blood pressure stays under control.
The problem we solve
Hypertension is one of the largest public health burdens in America. Roughly half of U.S. adults have high blood pressure, and only about one in five keep it controlled. It is a leading risk factor for heart attack, stroke, kidney disease, and death — yet it is also one of the most treatable conditions.
The gap between "treatable" and "controlled" is a problem of follow-up and adherence, not unknown medicine. That gap is widest among underserved, low-income, and language-barrier populations.
What makes us different
- Genuine bilingual design — not a translation checkbox, but interface, education, and summaries designed for limited-English-proficiency users.
- Privacy and on-device processing — your health data does not go to third-party clouds.
- Real subsidized access — funded by clinics, not marketing discounts.
- Clinical bridge — a dashboard that helps doctors see who needs attention, not another consumer wellness app.
- Low technology requirements — works offline, syncs later, no high-end phone needed.
Aligned with national priorities
Hypertension control is an explicit federal priority across Million Hearts, the National Hypertension Control Initiative (HRSA), CDC 6|18, the Surgeon General's Call to Action, and Healthy People 2030. CardioOK adds to that national effort — we do not compete with it.
Our boundaries
CardioOK is not a medical device. It classifies blood pressure ranges and organizes data for your care team. It never recommends treatment or adjusts doses. A reading in the crisis range always triggers guidance to seek care — no engagement mechanism can suppress that path.
