What mobile-app-ui-design does

This skill guides AI assistants through structured mobile screen generation. It enforces a 60/30/10 color distribution where a neutral base occupies sixty percent, secondary elements take thirty percent, and the accent color stays at ten percent for call-to-action elements. Typography gets constrained as well: a maximum of four font sizes and two weights per screen, with monospace variants dedicated to numbers and stats.

Layouts adhere to an 8-point grid system with all spacing values divisible by 4 or 8. The workflow places primary interactions in the bottom thumb zone and requires tap targets of at least 44×44pt. Shadows are tinted to match the background color instead of relying on harsh black shades. It also guides the model through four specific UI states: empty, loading, error, and success.

Because the instructions strictly enforce spacing multiples of 4 and 8, projects with custom arbitrary paddings will require manual adjustments.

What it helps with

  • structure mobile screen flows around the thumb reach zone
  • apply a 60/30/10 color system with background-tinted shadows
  • generate visual UI prototypes for Flutter, React Native, or SwiftUI
  • design empty states, error notices, and loading layouts

Example prompts for the agent

  • Design an onboarding flow for a personal budgeting app using SwiftUI styles.
  • Reorganize this checkout screen: move primary actions to the bottom thumb zone and apply 8pt spacing.
  • Create a fitness dashboard layout with monospace metrics and a 60/30/10 palette.
