saccade · /səˈkäd/ · rhymes with “facade”
A rapid movement of the eye between fixation points.
No surveys. No clicks. No opinions. Just look at two images and your unconscious gaze picks the winner. Powered by ARKit face tracking.
Two logos. Four hero images. Eight headshots. Drop in 2–12 images and Saccade generates every possible A/B pair.
Each pair appears for 3–8 seconds. Your iPhone's TrueDepth camera tracks where your gaze lingers. You don't choose — your eyes do.
Instant ranked results with preference strength bars. Share the results card with your team, your client, or your group chat.
Which version of your logo, icon, or wordmark actually draws the eye?
20 shots from a shoot. Your eyes pick the best ones faster than your brain.
Which landing page hero or YouTube thumbnail gets the longest look?
Pass the phone around. Aggregate unconscious preferences instead of subjective opinions.
You can't fake where your eyes go. Research shows gaze duration correlates with preference — even when you know you're being tracked. It's called the gaze cascade effect, and it's been used in commercial eye-tracking studies for decades.

Saccade brings lab-grade eye tracking to your pocket. Not 100% accurate — but consistently better than guessing, and infinitely faster than a survey.
Free on the App Store. Requires iPhone X or later (TrueDepth camera).
