Is this your startup?

A scan shows what a first visit looks like. Your real visitors show the rest: where they tap, what they skip, where they leave. UserProof records them and gives Claude Code the one fix that costs you the most signups, with the file and line. Free for 3 sites.

How we checked

We loaded the home page in Chromium as a 390px phone and a 1366px desktop, found the main button by its words (sign up, book a demo, get started and similar), tapped it once, and checked up to 3 pages for broken links and dead taps. Nothing was submitted. Each failed check costs the points shown. Full method.
