watchOS Platform

watchOS-specific development for Apple Watch experiences.

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

• fuse-ai-pilot:explore-codebase - Analyze existing watchOS patterns

• fuse-ai-pilot:research-expert - Verify latest watchOS 26 docs via Context7/Exa

• mcp__apple-docs__search_apple_docs - Check watchOS patterns

After implementation, run fuse-ai-pilot:sniper for validation.

Overview

When to Use

Design Considerations

Screen Size

• Small display, large touch targets

• Glanceable information

• Minimal text, clear icons

Interactions

• Digital Crown for scrolling/input

• Force Touch (older watches)

• Gestures: swipe, tap

Battery

• Minimize background work

• Use complications for updates

• Efficient data transfer

Best Practices

• Glanceable - Quick information access

• Large targets - Easy tapping

• Minimal input - Reduce typing

• Complications - Update watch face data

• Background refresh - Efficient updates

• Test on device - Simulator differs from hardware
