Please try BlinkMoreFree before you buy! Main difference: auto on/off eye tracking based on app you are using.

BlinkMore is a macOS menu bar application that helps reduce eye strain by fading your screen when you stare at it for too long without blinking. It uses automated eye-tracking and has option to only turn on eye tracking when using certain apps. I like to use with text-heavy tasks where I tend not to blink enough.

REQUIRES: macOS 14 (Sanoma) or later AND Mac built-in front facing camera.

PRIVACY: Everything happens right on your Mac—no data leaves your device or sticks around after you close the app. No accounts or personal information needed.

NOTE: Please try BlinkMoreFree and see if this works for you! There is no customer service (or refunds) for this app.
