What is EyesRhythm?
EyesRhythm is a free desktop application for macOS and Windows that uses your computer camera to monitor blinking patterns while you work at a screen. It calculates an Ocular Rhythm Index from zero to one hundred by measuring both how frequently you blink and how evenly those blinks are spaced throughout the day.
The app runs entirely on your local machine without requiring an account, license key, or internet connection. Camera frames are processed and discarded immediately, so no video data leaves your computer. The interface stays as a small dockable window beside your active applications.
A companion feature called Poise tracks which directions you turn your head using thirty degree increments, highlighting unused angles in red to encourage movement. Users can enable optional visual pulses, sound alerts, or a click tone for each detected blink. A two minute guided session helps build consistent blinking habits.

EyesRhythm FAQ
Is EyesRhythm free to use?
Yes. The application is completely free to download and run on macOS and Windows. There is no subscription fee, no premium tier, and no license key required.
Does EyesRhythm require an internet connection or cloud account?
No. The app processes all camera frames locally on your computer and discards them immediately. It does not collect analytics, upload video, or require an account or license key.
What is the difference between EyesRhythm and a simple blink counter?
A standard counter only tallies total blinks. EyesRhythm measures both the frequency and the regularity of blinks, combining them into a single Ocular Rhythm Index score from zero to one hundred.
Can I use EyesRhythm with a laptop built in camera?
Yes. The software works with the built in camera on Mac or Windows laptops, as well as external USB webcams. You should sit in your normal working position so the camera can see your eyes.
Does EyesRhythm support Linux?
The website does not say. The product page only lists macOS and Windows as supported operating systems.
