A free app that turns 30 seconds of daily logging into a cardiovascular dataset built around women — including the menstrual cycle most research ignores.
Heart disease is the leading cause of death in women. Yet until 1993, federal law did not require women to be included in the clinical research that shaped how hearts are diagnosed and treated — so much of that science was built on men. Women are still more likely to have a heart attack missed or symptoms dismissed, in part because the data was never collected.
Sources: heart disease as the leading cause of death in women — U.S. Centers for Disease Control and Prevention. The 1993 inclusion requirement — NIH Revitalization Act of 1993, which mandated the inclusion of women in NIH-funded clinical research.
Sleep, stress, caffeine, symptoms, your cycle. No medical jargon, no devices required — just a few taps.
Heartwise surfaces trends in your own data over time, so you can see how rest, stress, and your cycle move with your heart.
Every entry also joins a women's cardiovascular cohort — building the research that should have existed decades ago.
Sleep is when your heart recovers. Short or broken sleep is linked to higher blood pressure and lower heart-rate variability — a key marker of cardiovascular resilience.
Caffeine can briefly raise heart rate and blood pressure, and when you have it matters as much as how much. Logging timing reveals your own response.
Hydration shapes blood volume, which affects how hard your heart has to work. Even mild dehydration can nudge heart rate up.
Stress drives cortisol, which influences blood pressure, heart rate, and heart-rate variability over time. Noting it links how you feel to what your heart is doing.
Hormones across your cycle shift heart rate, HRV, and blood-vessel tone — yet most heart research ignores the cycle entirely. Tracking phase, day, and symptoms is core to what makes Heartwise different.
Regular movement is one of the strongest protectors of cardiovascular health, and it shapes measures like VO2 max. Logging it shows how activity relates to your other signals.
Alcohol is associated with higher blood pressure and can trigger palpitations or irregular rhythms in some people. Tracking it surfaces patterns you might otherwise miss.
Slow, controlled breathing activates the vagus nerve and can raise heart-rate variability — a sign of a flexible, resilient heart. Logging it tracks that effect over time.
Women more often experience fatigue, nausea, shortness of breath, or jaw and back pain rather than classic chest pain — and are more likely to have a heart attack misdiagnosed.
Across the cycle, hormones shift heart rate, heart-rate variability, and blood-vessel tone. Tracking it puts every other reading in context.
A single reading bounces around. Patterns over weeks tell the real story — and that's what Heartwise helps you see.
Your name, email, and identifiable records are never sold. Heartwise is funded by licensing de-identified, aggregated research data — partners never receive anything that identifies you. If we ever introduce anything else, we'll tell you plainly first.
Your entries are encrypted in transit and at rest, stored securely.
Export or delete your data anytime. Research participation is opt-in and tied to consent you give and can withdraw.
Heartwise is built to independent research-ethics standards, with formal IRB review planned before any research data is shared.
Heartwise is assembling a longitudinal, consented, cycle-aware cardiovascular cohort of women — engaged, well-characterized, and logging over time.
Academic cardiology, CROs, and health systems — let's talk about partnership and recruitment.
Partner with HeartwiseIn my senior year of high school, I took a women's health class — and for the first time, I learned that heart disease looks completely different in women than in men. The symptoms are different. The warning signs are different. But for decades, the treatment, the research, and the diagnostic criteria have all been built around men.
Women are still being sent home from ERs with undiagnosed heart attacks. Still being told their symptoms are anxiety. Still dying at higher rates after cardiac events — partly because the data to help them simply doesn't exist yet.
I built Heartwise to change that. Every log submitted is a data point that has never existed before. Women who use this app aren't just tracking their health — they're helping build the evidence that will change how women's heart disease is treated and diagnosed for generations to come.
Yes. No subscription, and we never sell your personal information. Heartwise is funded by licensing de-identified, aggregated research data to research partners — including academic institutions and commercial organizations. They never receive anything that identifies you. You're funded by the research, not the other way around.
Your entries are encrypted in transit and at rest. You can export or delete your data anytime, and research use is opt-in through consent you control and can withdraw.
No. Logging takes about 30 seconds a day on your phone. If you do use a wearable, you'll be able to connect it later.
Heartwise builds a longitudinal, cycle-aware cardiovascular dataset for women — the kind that has historically been missing — so patterns can be studied over time rather than in a single snapshot.
Heartwise is an independent platform (Heartwise LLC) founded to close the gender gap in cardiovascular research.
