A free app for the one health number you can measure at home, and a membership built around it.
Cento sits alongside your healthcare, never in place of it.
Adults who want to understand their blood pressure at home. Usually one of four people.
You need your own blood pressure monitor. Cento records and explains readings, it does not take them. And Cento is for adults 18 and over.
No. Cento is a wellness companion, not a diagnostic tool. It helps you take a reading well and stay consistent. For anything about your health, speak to your doctor.
Any validated upper arm monitor works. If you are not sure yours is validated, Cento checks it against the independent registries for you.
Do not own one yet? Run the BP Monitor Check on this site first. It takes about a minute.
It scores how well the reading was taken. Not the number, and not you. Rest, posture, arm position, cuff fit, caffeine, talking and time of day all count, with weights from published research. A high score is a number worth weighing. A low score is just a noisy moment.
Always. Your readings are never used for advertising, there is no advertising software in the app, and we never send health details in a notification or an email.
A calm place for your blood pressure.
