Pulse Modality
Measure Your Heartbeat
Press your fingertip firmly over your phone's rear camera. We read the colour shift under your skin for 10 seconds, then translate it into a piece of music that mirrors your heart.
How to hold your finger
- Lay the phone flat on a surface, camera up
- Place finger pad-down, covering BOTH lens and flash
- Hold still until the signal goes green, then tap Start

How your pulse becomes music
BPM
Beats per minute from your fingertip's red-channel pulse
→ song tempo
R-R Intervals
Time between successive heartbeats
→ rhythm grid
HRV
Beat-to-beat timing variability (SDNN / RMSSD)
→ groove + swing
Signal Quality
Red-channel signal-to-noise ratio
→ confidence-weighted
Tips for a clean reading
- Steady pressure — not too hard, not too light
- Warm fingers read better than cold ones
- Hold still for the full 10 seconds — no talking, no repositioning
