Stop mouth breathing.

NoseFlow sits in the background, checks your mouth pattern on an interval you choose, and notifies you when you start breathing through your mouth so you can close it and breathe through your nose again.

How it works

Calibrate once. Get nudged when your mouth opens.

Vision analysis runs on your Mac. Camera frames are used to measure mouth position. They are not uploaded.

01

Calibrate

Sit in your usual working position, face the camera, close your mouth, and let NoseFlow learn that baseline.

02

Work as normal

Minimize the window. NoseFlow keeps checking on your interval while you use other apps.

03

Get a prompt

If mouth breathing is detected, a notification asks you to close your mouth and breathe through your nose.

Why it exists

Nasal breathing is the default the body is built for.

Mouth breathing while you work is easy to miss. NoseFlow is a habit cue, not a medical device. It helps you notice the pattern and return to nasal breathing.

Quick start

A few minutes of setup.

  1. Allow camera and notification permissions when macOS asks.
  2. Sit where you normally work, with your face clearly visible and lighting that is not too dark.
  3. Close your mouth, relax your face, and complete calibration.
  4. Set a check interval from the nose icon in the top right of the app window.
  5. Minimize NoseFlow or switch to another window. It continues in the background.

If your head angle or lighting changes a lot, recalibrate from the same nose icon.

Help

Common questions.

Does video leave my Mac?

Detection uses Apple Vision on the device. NoseFlow is built to watch mouth position locally, not to record or upload your camera feed.

Why do I need calibration?

People sit at different distances and angles. Calibration sets a closed-mouth baseline for your usual posture so alerts are less noisy.

Is this a medical product?

No. NoseFlow is a habit reminder for nasal breathing. It is not a diagnosis, treatment, or medical device.
