01Measure
Point your phone at your face for sixty seconds. Our on-device rPPG reads RMSSD, SDNN, resting HR — no wearable, video stays on the device. Your coach reads the result before you.

Box, 4-7-8, physiological sigh, coherent 5.5, wind-down stacks. Each ritual theme shifts the ring palette and the ambient sound — one tap from any stress spike.
03Reflect
Peak-hour heatmap, sleep × HRV correlation, pattern effectiveness. A persona-matched coach narrates the week every Sunday.
Baseline · at a glance

Measured, not marketed
Each card is one real session: pre-stress score, post-stress score, and the pattern that moved the needle.
