## 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 and the 
  flash, hold still for about 20 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 color, and the camera reads 
  that rhythm using a technique called photoplethysmography (PPG). Cardia saves a number only when two 
  independent methods agree on it. No video is recorded, and nothing from the camera leaves your phone.

  WHAT YOU GET

  • Heart rate and HRV from one short reading                               
  • A live camera view and pulse waveform while you measure                 
  • Telephoto camera option for a steadier reading on supported iPhones     
  • Paced breathing at six breaths a minute, with your pulse on screen and your first and last minute side by side
  • A 7-day chart on your Home screen                                       
  • Tag readings (morning, after coffee, after exercise) and add notes      
  • A weekly review of your readings and sessions                           
  • A daily reminder that skips days you've already measured
