Mobile Game UI Responsive Design System Creator
Design scalable mobile game UI systems across devices with Claude validation
What You Can Do
You can build device-aware UI design systems that automatically scale across fragmented mobile ecosystems without redesigning for each screen size. Claude helps you define parametric design tokens, validate safe zones and touch target sizes, document aspect ratio handling strategies, and iterate on layouts for iOS and Android simultaneously—reducing rework and ensuring visual consistency across platform variants.
Features
Define target phones, tablets, and aspect ratios with Claude-assisted breakpoint calculation
Claude checks that UI elements scale proportionally while maintaining gameplay visibility and touch usability
Generate and validate status bar, notch, and home indicator boundaries for iOS and Android edge cases
Validate that buttons and interactive elements meet minimum size requirements (44-48pt) across all devices
Create systematic spacing, typography, and color scales that Claude helps you organize and validate
Produce developer-ready specifications with margins, anchoring rules, and responsive constraints
Claude assesses UI adaptation complexity when expanding from mobile to tablet or vice versa
Refine layouts across multiple screen sizes with Claude feedback on visual hierarchy and readability
