Before a single participant sees your study, test it yourself — on the exact device frames they will use. Mobile, tablet, and desktop layouts render pixel-perfect inside realistic device chrome, with conditional logic and branching live and interactive.

iPhone, iPhone Landscape, iPad, iPad Landscape, and desktop are all one click apart. Layout breakpoints, type scaling, and touch targets are rendered exactly as the participant will experience them.
Tap, type, choose, and submit. Conditional logic and branching fire just as they will in production, so you can validate the participant's path through your protocol before going live. No data is saved — Preview is a sandbox.
Run the flow as many times as you need. Reset clears the in-memory answers and starts from the top — perfect for QA passes before launch.
