GUIDED BLOOD PRESSURE SESSIONS

Take two or three cuff readings with a built-in rest timer. CardioLog groups the readings and provides a session average for easier record keeping.

REPORTS FOR APPOINTMENTS

Create a clear PDF report from your recorded history and share it by email, messaging, or print when preparing for an appointment. Free users receive limited PDF export, while CardioLog Pro includes deeper report sections and unlimited export.

REMINDERS THAT FIT YOUR ROUTINE

Set local reminders for blood pressure checks, blood sugar checks, and medication routines. CardioLog Pro adds smart reminders and follow-ups to help you stay consistent.

PRIVACY BY DESIGN

Your blood pressure and blood sugar readings stay on your device. CardioLog does not require an account or sync your health records to a cloud service.

Limited privacy-safe operational analytics and crash reporting help improve reliability. They do not include your readings, profile names, notes, dates of birth, or report content. See the Data Safety section and Privacy Policy for details.

NO THIRD-PARTY ADS

CardioLog does not display third-party advertising. CardioLog Pro is optional, and core tracking remains free.

IMPORTANT

CardioLog does not measure blood pressure or blood glucose. Enter readings from a blood pressure cuff or glucose meter.

CardioLog is a recording and reporting tool, not a diagnostic system or a substitute for professional medical advice. Always consult a qualified healthcare professional for health decisions.
