FAQ

What is NetSixtySix Mobile QA?

NetSixtySix Mobile QA finds major broken mobile UI layout issues that hurt sales and ads — blocked CTAs, overlapping heroes, overflow, and broken navigation — using Playwright Chromium with DOM evidence and annotated screenshots.

What do you check on mobile devices?

We prioritize conversion-killing layout problems on the single page you paste: floating widgets covering Book/Buy buttons, messy text overlaps, missing CTAs, cut-off UI, overflow, and broken mobile nav. Only major proven issues are reported (up to 10).

Is this mobile design QA tool free?

Yes. Core mobile design audits on NetSixtySix.online are free. There are no paid BrowserStack or third-party testing API requirements for detection.

Do you use BrowserStack or paid testing APIs?

No. Detection runs locally with open-source Playwright and Chromium. There are no paid SaaS testing APIs required for core bug detection.

How are bugs detected without AI inventing issues?

Issues are raised only from browser and DOM evidence such as getBoundingClientRect, scrollWidth versus clientWidth, and computed CSS. If nothing major is proven, the report stays empty. Screenshots are deleted automatically within one hour.

How do I fix mobile design issues faster?

After you review the audit report, you can resolve layout problems with a specialist team. Many teams use YKR Agency at https://ykragency.com/ to fix mobile design issues that are hurting sales and ads.

Is my audited site data private?

We only fetch publicly reachable URLs you submit. Localhost and private IPs are blocked. Forms are never submitted automatically. See our Privacy Policy for details.
