Cross-Platform Consistency

Day 19 of 30 · The Playbook 2026 – Masterclass for Designers

Align tokens, components, and patterns across web/iOS/Android.

Learning Goal

  • Platform mapping: what is shared, what is native-specific.
  • Token export to web/ios/android.
  • Component divergence rules: when allowed (e.g., date picker).
  • Document examples and bans.

Why This Matters

  • Users expect native patterns but same brand.
  • Single source reduces maintenance.
  • Diverge only with rationale.

Explanation

  • Shared: color, type, icons, tone.
  • Different: navigation patterns, native inputs.
  • Rule: documented divergence + reason + tracking.

Examples

Bad: Web and mobile use different brand palettes.

Good: Same brand tokens; native navigation allowed.

Guided Exercise

  1. Create platform mapping table: shared elements, divergent patterns.
  2. Define divergence approval process.
  3. Document token export pipeline.

Independent Exercise

Pick a component (modal) and note platform differences.

Self-Check

  • Platform mapping exists.
  • Divergences documented and justified.
  • Token export known.
