Preference Test

A preference test shows people two or three versions of a design and asks which one they prefer for a specific reason, such as which makes it clearer how to book. It is a quick way to settle a design argument with evidence from the people who will use the thing.

The tool will not call a winner under 20 responses, because a handful of votes can swing either way by chance. With 20 or more it shows a p-value hint: an exact binomial test for two designs and a chi-square test for three. Treat it as a hint, not proof, because your participants are self-selected.

Each participant sees the designs in a random order, and the tool records the order they saw, so position bias (people favouring the first or left-hand option) is spread across the designs instead of favouring one. Results are always counted against the original A, B and C.

One specific, answerable question beats "which do you prefer?". Try "which makes it clearer how to book?" or "which would you trust with your payment details?". The optional follow-up (why did you choose it?) is where the useful detail comes from, so read the reasons, not just the percentages.

Screenshots or mockups of the same screen at the same size, so the only difference is the thing you are testing. Upload PNG, JPG or WebP (they are resized for you), or paste a link to an image that is already hosted. Participants can tap any design to see it full size.

It tells you which design people pick and what they say about it, not whether the design works. Pair it with a first-click or task-based test before you ship, and remember there is no participant panel here, so you recruit your own.
