A copy for one computer.

Simple terms for buying EyesRhythm from this site.

You are buying a packaged copy of EyesRhythm for macOS or Windows. $12 one time. No subscription. One operating system, not both. One computer.

After you pay, you get a license key and that OS’s installer by email. On first launch you register the key. After that the app stays on your machine.

The key is for you. Please do not share or resell it. A Mac key will not unlock Windows, and a Windows key will not unlock Mac.

EyesRhythm watches blink rhythm through your camera, on this computer. It is a wellness companion. It is not a medical device, and it is not meant to diagnose, treat, or prevent disease.

You need a working webcam and a current macOS or Windows version. Camera permission is yours to give. Without it, the companion cannot count blinks. Tested on Intel Core i7 and on Mac processors. We recommend this configuration.

Try it for 7 days. If you find the app not worth it, please let us know the reason. Mail hello@eyesrhythm.com from the same email address you used during purchase. Details are on the refunds page.
