Cardia: Blood Pressure & Sugar

Cardia is a calm, private logbook for your blood pressure, blood sugar, and heart rate. Built for people managing hypertension or diabetes, for caregivers tracking a parent's readings, and for anyone who wants a clear picture of their daily wellness — without the noise.

No gamified scores. No misleading single-number "health grades." Just your actual readings, classified against established medical guidelines, with plain-language context.

🩺 BLOOD PRESSURE TRACKING

Record systolic, diastolic, and pulse with one tap. Cardia classifies each reading against the ACC/AHA 2017 or ESC/ESH 2018 guidelines — you choose which to follow.

Tag readings by time of day, position, or arm.

See trends across days, weeks, and months.

Get reminders so you never skip a measurement.

Quickly review your history before doctor visits.

🩸 BLOOD SUGAR LOG

A complete glucose journal for fasting, post-meal, and HbA1c readings. Cardia supports all three standard test types — FPG, OGTT, and HbA1c — with classification based on WHO and IDF criteria.

Switch between mg/dL and mmol/L instantly.

Tag readings by meal context: fasting, pre-meal, post-meal, bedtime.

Track your prediabetes or diabetes management over time.

Add notes about food, medication, or how you felt.

❤️ HEART RATE

Log your pulse manually, or measure it on the spot using your phone's camera. Cardia's optional PPG (photoplethysmography) feature analyzes light changes at your fingertip to estimate your pulse — all on your device, with nothing stored or shared.

📊 SMART DASHBOARD

See each metric on its own terms — not jumbled into a meaningless composite score. Trend charts highlight what's changed and what's stable, with recommendations that match each reading's zone.

🔒 PRIVATE BY DESIGN

Your health data stays on your device. Cardia has no server holding your readings, no account required, no cloud sync that you didn't ask for. Camera frames from heart rate measurement are processed in real time and immediately discarded.

WHO CARDIA IS FOR

People managing hypertension or type 2 diabetes.

Adults tracking proactively for prevention and peace of mind.

Caregivers monitoring an elderly parent's vitals.

Anyone preparing readings to share with their doctor.

CARDIA IS WELLNESS, NOT MEDICAL

Cardia is a personal wellness logbook. It is not a medical device, does not diagnose any condition, and is not a substitute for professional medical care. Always consult your doctor about your readings, especially if they fall outside normal ranges. In an emergency, call your local emergency number.

The camera-based heart rate feature is an estimate for general wellness purposes only — not a medical-grade measurement.

PERMISSIONS WE USE

Camera — only when you tap to measure your heart rate; processed on-device, never stored.

Notifications and exact alarms — to send reminders at the times you set.

Vibrate — for subtle haptic feedback.

We do not request location, contacts, microphone, or storage access.

NOT AFFILIATED

Cardia is an independent app developed by MTD Technology Company Limited (Tarunow). Cardia is not affiliated with, endorsed by, or connected to AliveCor, Inc. or its Kardia® products.
