Presio: Blood Pressure Log

Presio is the simplest, most private way to track your blood pressure on iPhone. No account. No cloud. No subscription to get started. Just open the app, log your reading, and understand your health.

YOUR DATA STAYS ON YOUR DEVICE
Every blood pressure reading, note, and symptom you log is stored locally on your iPhone — never uploaded, never shared, never sold. Presio is completely free to use and requires no account to get started.

NOT A MEDICAL DEVICE
Presio is a personal tracking tool, not a diagnostic application. Blood pressure categories shown in the app (Optimal, Normal, High Normal, Hypertension I / II / III, Low) follow the widely accepted ESC/ESH 2023 classification used by healthcare professionals worldwide. These labels are provided for reference only and do not constitute medical advice, diagnosis, or treatment. Always consult your doctor about your blood pressure results.
