Store description excerpt

**Your heart rate. And your rhythm. No watch required.** Cardia turns your iPhone's camera and flash into a pulse sensor. Rest a fingertip over the lens, hold still for about 30 seconds, and get two numbers: heart rate (BPM) and heart rate variability (RMSSD). **HOW IT WORKS** Light from the flash passes through your fingertip. Each heartbeat shifts its colour, and the camera reads that rhythm using a technique called photoplethysmography (PPG). Nothing is recorded, and video never leaves your phone. **WHAT YOU GET** • Heart rate and HRV from one 30-second reading • A live camera view and pulse waveform while you take it • Charts over 7, 30, and 90 days • Context tags such as morning, after coffee, after exercise, and more, plus notes • Your averages by context, side by side, so you can compare them • A daily reminder at the time you pick **CARDIA PRO** • Unlimited readings. The free version includes one reading per day • Filter your history by context • Sync readings to Apple Health • No commitment. Cancel anytime. **PRIVATE BY DESIGN** Readings stay on your phone. Export everything as CSV whenever you like. No account. No ads. Cardia is a wellness tool. It is not a medical device and does not diagnose, treat, or monitor any condition.
