+## Work on FRE-58: Energy System & Starter Pack IAP
+
+### Accomplished Today
+
+**IAP Integration Complete:**
+
+1. **Created `hooks/useIap.ts`** - React hook for in-app purchases:
+   - Auto-initializes IAP connection on mount
+   - Loads product info from App Store/Play Store
+   - Provides `purchaseProduct()` method with proper callback handling
+   - Exposes real price, title, description from store
+   - Handles connection state and errors
+
+2. **Updated `app/(tabs)/dungeon/purchase.tsx`:**
+   - Integrated real IAP flow instead of mock purchase
+   - Shows actual store price dynamically (e.g., "$1.99" or "€1.99")
+   - Added loading overlay while connecting to payment system
+   - Purchase button shows "Processing..." during transaction
+   - Only grants unlimited energy after successful purchase confirmation
+   - Properly handles cancelled purchases without error alerts
+
+3. **Updated `app/_layout.tsx`:**
+   - Added IAP initialization in `RootLayoutNav` useEffect
+   - Initializes alongside database and sync manager on user sign-in
+   - Sets up event listeners for purchase updates
+   - Gracefully handles init failures (will retry on demand)
+
+### Technical Details
+
+**Purchase Flow:**
+```
+User clicks "Buy Now"
+    ↓
+Show confirmation with real price from store
+    ↓
+Call purchaseProduct(PRODUCT_IDS.UNLIMITED_ENERGY_DAILY)
+    ↓
+react-native-iap opens native payment sheet
+    ↓
+User confirms payment in OS dialog
+    ↓
+purchaseUpdatedEvent fires → IAP service consumes purchase
+    ↓
+Hook callback resolves → grant unlimited energy via energyService
+    ↓
+Show success alert, navigate back
+```
