Notice the shift.
Zen reads three signals from your face on this device: blink rate, brow tension, and head motion. Use it as a mirror when something feels off, before you can name what it is.

If you are panicking, Zen will speak slower and use shorter sentences. Tap below to share your camera; the video stays in this browser, only the calm-vs-elevated state shapes how Zen speaks.

When to use this
- Before a meeting, check whether you are still spun up from the last one.
- During a check-in, pair the felt-sense with the label so the next time is easier to notice.
- After a grounding exercise, watch the elevation drop and breath rate slow.
