Status: Complete iOS PRs: #312 (5a), #313 (5b), #314 (5c)

Overview

Phase 5 implements the Analytics system for Archery Apprentice, providing archers with insights into their shooting performance across equipment, time periods, and scoring patterns.

Phase 5a: Analytics Dashboard Foundation

PR: #312 | Status: Complete

Foundation implementation providing:

• Summary statistics (total rounds, arrows shot, average score)
• Recent completed rounds list
• Equipment drift statistics
• Time-range filtering fixes

Guide: Analytics Dashboard Implementation Guide

Phase 5b: Individual Equipment Analytics

PR: #313 | Status: Complete

Extended analytics with:

• Individual equipment performance tracking (per riser, limbs, sight, arrows, stabilizer)
• ArrowEquipmentSnapshot entity for linking arrows to equipment
• 15 new EquipmentStatsDao queries
• Historical trend bar chart visualization
• Time-range filtering (7d, 30d, 90d, All)
• MainTabView integration with DI
• N+1 query optimization with Swift TaskGroup

Phase 5c: Equipment Comparison

PR: #314 | Status: Complete

Equipment comparison feature achieving Android parity:

• Side-by-side bow setup comparison
• Setup picker with A vs B selection
• Performance stats comparison (average score, accuracy, consistency)
• Delta visualization with color coding (green = better, red = worse)
• Drift statistics comparison
• Time-range filtering with @AppStorage persistence
• Full TDD implementation (36 tests)

Guide: Equipment Comparison Guide

Key Patterns Documented:

• KotlinLong interop pattern for KMP bridging
• @AppStorage persistence pattern for user preferences
