What we publish
The site combines interactive tests with practical guides. Tool pages explain how measurements are calculated. Guide pages help readers interpret a score, troubleshoot a device, and understand what a browser can and cannot measure.
Editorial approach
Content is written for an international English-speaking audience, reviewed for internal consistency, and updated when browser behavior or common device workflows change. We do not present informal browser results as medical, diagnostic, employment, or safety certifications.
Corrections
If a tool behaves incorrectly on a supported browser or an explanation needs correction, send the page URL, browser version, device type, and steps to reproduce through the contact page.
