Pulse and breathing, no wearable
A plain webcam is enough. Flow estimates pulse, breathing, blink rate and gaze, then shows the signal it measured instead of reducing you to a productivity score.
Eyes on the page,brain gone.
Flow is a focus app that watches your pulse, breathing, blinks and gaze through a plain webcam, catching drift in the moment and turning every session into insights on when and why your focus slips.
What it notices
Features
What Flow measures, notices and offers during a work session.
02 · context
It notices drift, not just time
Flow combines rolling physiology with the active app and window context to distinguish focused work, drifting, spiralling, warmup and missing signal.
03 · in the moment
A quiet nudge when it helps
When the evidence is strong enough, Flow can offer a short reset or guided breathing. Every intervention is optional and dismissible in one click.
04 · afterwards
A session you can understand later
Afterward, Flow turns your derived signals and state timeline into a plain-language account, with enough detail to see where its reading may have been wrong.
Four minutes to a baseline. Then it just watches.
No account needed, and your camera frames never leave this machine. Camera-based physiological sensing — not a medical device, and it diagnoses nothing.
