Cordiary

Your blood pressure, your device, your data. No subscriptions, no cloud, no tracking. Just a simple diary that respects your privacy – and takes up barely any space.

Take control of your heart health in seconds. Record your readings, spot trends at a glance, and share clear reports with your doctor – all without subscriptions, accounts, or ads.

YOUR READINGS, BEAUTIFULLY ORGANIZED Enter systolic, diastolic, and pulse values quickly. Add notes like "after exercise" or "before medication" and let the app automatically detect the time of day. Every entry is color-coded using the WHO classification so you can instantly see where you stand.

SEE THE BIGGER PICTURE Interactive charts show your progress over 7, 30, or 90 days. Compare morning and evening averages side by side. A trend indicator on the dashboard tells you at a glance whether your values are rising, falling, or staying stable compared to yesterday.

SHARE WITH YOUR DOCTOR Generate professional PDF reports or export raw data as CSV – perfect for your next appointment. Select a date range, preview the summary, and share it via email, message, or AirDrop.

APPLE HEALTH & APPLE WATCH Optionally sync your data with Apple Health. Import existing readings from other apps or devices. The companion Watch app lets you log new entries directly from your wrist using the Digital Crown, and complications keep your latest reading visible on your watch face.

PRIVACY BY DESIGN Your data stays on your device. Optional iCloud sync keeps your iPhone and iPad in sync – through your own iCloud account, not our servers. No registration. No tracking. No data collection.

WIDGET & REMINDERS A home screen widget shows your latest reading with a sparkline of your recent trend. Set separate morning and evening reminders so you never miss a measurement.

BASED ON SCIENCE The color classification follows established guidelines from the World Health Organization (WHO), the European Society of Hypertension (ESH), and the International Society of Hypertension (ISH). All sources are cited directly in the app.

Designed and developed in Germany.
