Estimate focus on your study page.

LearnFit will treat the page you started from as the first verified study page. It calculates a focus estimate only while a verified page is active and your eyes are visible.

Blink naturally. Normal blinking is expected. LearnFit currently supports screen-based study; looking down far enough to leave the camera creates a no-signal gap, not a penalty.

Chrome needs one visible permission step before the private background camera can start. Frames, page addresses, and titles stay on this device.
