Apple-inspired continuous corners (squircle) with smooth, superelliptical rounding. Creates a premium, polished feel that mimics native iOS design. Perfect for mobile-first apps and premium products.
Use the Squircle iOS radius system for Apple-inspired, premium corners. Border radii: 10px for buttons and inputs, 14px for cards, 20px for modals and sheets, 9999px for avatars and pills. These values mimic iOS continuous corners (squircle shape). Pair with subtle shadows and clean spacing for an authentic premium feel. All corners should feel smooth and intentional — no mixing of sharp and round.
