About This Tool
Review common mobile usability factors such as viewport configuration, responsive layout, readable controls and page behavior on smaller screens.
How to Use It
Run the analysis and review mobile-specific findings, then reproduce important issues on real phones and different viewport widths.
How It Works
Mobile UX depends on responsive CSS, viewport configuration, touch targets, typography, content hierarchy and performance. Automated checks identify detectable patterns but cannot fully reproduce human interaction.
Practical Example
A navigation menu that overflows a 360-pixel viewport can hide important links. Responsive navigation and appropriately sized controls can address the issue.
