this app doesn't work. First of all, not all functions are visible on the screen, they are hidden by the bottom edge of the screen. Why did the created form bind itself to the page, so that I can no longer design the page in the theme editor, and I can no longer change the position of this form on the page. What is the

Excelente, una app que cumple lo que promete.
I've tried nearly all the form builder apps out there and this feels the best of the bunch to me. Easy to style, easy to implement, and support is very fast to answer questions. They are actively working on adding functionality and already implemented a couple suggestions I had. Highly recommended!
Great app and outstanding support. Responses were fast, clear, and genuinely helpful. The team took the time to investigate my questions with their technical team and is already working on improvements. Highly recommended.

AppRanks does not track migration tooling directly — this is a category-specific capability worth verifying before commitment.
