<objective> Covers watchOS-specific development for Apple Watch: watch-face complications for glanceable data, workout sessions and fitness tracking, HealthKit access to health metrics, and Watch Connectivity for iPhone-Watch sync.

Includes design considerations specific to the platform — small display with large touch targets, glanceable information with minimal text, Digital Crown scrolling/input, Force Touch on older watches, swipe/tap gestures, and battery-conscious background work.

Best practices: keep information glanceable, use large tap targets, minimize text input, drive watch-face updates through complications, use efficient background refresh, and always validate on real hardware since the simulator behaves differently. </objective>

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

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
