# watchOS Platform

watchOS-specific development for Apple Watch experiences.

## Agent Workflow (MANDATORY)

Before ANY implementation, launch in parallel:

1. **fuse-ai-pilot:explore-codebase** - Analyze existing watchOS patterns
2. **fuse-ai-pilot:research-expert** - Verify latest watchOS 26 docs via Context7/Exa
3. **mcp__apple-docs__search_apple_docs** - Check watchOS patterns

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

## Overview

### When to Use

- Building Apple Watch apps
- Creating watch face complications
- Workout and fitness tracking
- Health data access (HealthKit)
- iPhone-Watch communication

### Why watchOS Skill

| Feature | Benefit |
|---------|---------|
| Complications | Glanceable data on watch face |
| Workouts | Fitness and health tracking |
| HealthKit | Access health metrics |
| Connectivity | Sync with iPhone |

## Reference Guide

| Need | Reference |
|------|-----------|
| Watch face complications | [complications.md](references/complications.md) |
| Workout sessions, HealthKit | [workouts.md](references/workouts.md) |
| iPhone ↔ Watch sync | [watch-connectivity.md](references/watch-connectivity.md) |

## 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

1. **Glanceable** - Quick information access
2. **Large targets** - Easy tapping
3. **Minimal input** - Reduce typing
4. **Complications** - Update watch face data
5. **Background refresh** - Efficient updates
6. **Test on device** - Simulator differs from hardware
