We use the following 3 steps to get your results: 

  1. Track your heartbeat through the phone camera & flash with a method called photoplethysmography, or PPG.

  2. Analyze the variation in the intervals between your heart beats with a method called heart rate variability analysis, or HRV analysis.

  3. Clarify what the results mean for you personally by taking into account your nervous system type, time of day, your past measurement results, and a ton of other data.

Sound like magic? Let’s talk about each of these steps in a bit more detail.
