Claude Code audit finds a phone tap bug on a coloring site

What the research found

A solo developer's Claude Code audit of the tintly.art coloring site found a line-tap bug that sent phone taps through to the background, plus a Google sign-in popup that blocked signups, and the fixes are now live.

Claims and how well the evidence supports them

1. Taps landing on drawn lines passed through to the background, causing rage-taps for about 1 in 4 phone users 97%
2. Google sign-in popup appeared 31 times with zero sign-ins before being moved to after coloring 98%
3. A $3 sale price (struck through from $7) was tested for a Halloween coloring book PDF 99%
4. A live test moved a snowman page from 0% to 69% in 210 taps after the fix 98%
