## What is Cardia?

**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.
