A/B testing. With your eyes. No surveys. No clicks. No opinions. Just look at two images and your unconscious gaze picks the winner. HOW IT WORKS 1. Upload your variants — two logos, four hero images, eight headshots. Add 2-12 images and Saccade generates every possible A/B pair. 2. Just look — each pair appears for 3-8 seconds. Your iPhone's TrueDepth camera tracks where your gaze lingers. You don't choose — your eyes do. 3. See what wins — instant ranked results with preference strength bars. Share the results card with your team, your client, or your group chat. WHY IT WORKS 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. WHAT PEOPLE TEST • Logo & brand variants • Photo selects from a shoot • Hero images & thumbnails • Color palettes & font samples • Baby names & vacation spots • Team & client testing — pass the phone around 100% PRIVATE • No account required — ever • No data leaves your device • No cloud, no analytics, no tracking • Camera used only for real-time gaze detection — no photos or video of your face are recorded Try Emoji Duel — a built-in game that lets you experience eye tracking instantly, no setup needed. Requires iPhone X or later.
