Pre-launch app check — the numbers said no overlap, the screenshot said otherwise
Summary in three lines
- Before submitting a campus chatbot app, we had an AI agent open all 147 URLs, found 12 pages missing titles and filled them in four languages.
- Position math said nothing overlapped, but the screenshot showed a button hidden 30px under the input box and the input box sinking 12px into the nav bar.
- On narrow phones the title wrapped to two lines; truncating it cut the brand name in half, so we narrowed the language button instead.
What we learned
- Let machines measure what can be measured; let a person look at screenshots for how it looks.
- Replace hard-coded positions with layers stacked from the real heights, so later changes do not misalign them.
FAQ
Why did the math miss the overlap?
Positions were fixed numbers measured on an older layout. The real bars got taller, so comparing old numbers showed no overlap.
What is the pre-launch check order?
Check every page title, run the overlap math, screenshot at the smallest phone size, look with your own eyes, then re-shoot anything you fixed.
