Free Mobile Tool
Test whether your website works properly on mobile devices. Check viewport configuration, tap target sizes, font readability, and responsive design issues.
This tool evaluates your site's mobile experience across multiple dimensions. It checks for a properly configured viewport meta tag, adequate tap target sizes, readable font sizes without zooming, responsive images, content width fitting the screen, web app manifest presence, and touch icon configuration. It also pulls mobile-specific scores from Google's Lighthouse engine.
Over 60% of web traffic comes from mobile devices, and Google uses mobile-first indexing. If your site doesn't work well on phones, you're losing both visitors and search rankings. Small tap targets frustrate users, tiny fonts drive them away, and content that overflows the screen makes your site look broken. Every second of friction costs conversions.
