+# 🔧 Guide de dépannage - WalletTracker
+
+## Problème : L'app charge jusqu'au timeout après scan du QR code
+
+### ✅ Solutions appliquées
+
+1. **Mise à jour des dépendances incompatibles**
+   ```bash
+   npx expo install --fix
+   ```
+
+2. **Configuration Metro améliorée**
+   - Ajout de `metro.config.js` avec timeout augmenté
+   - Optimisation du bundler
+
+3. **Graphiques temporairement désactivés**
+   - `react-native-chart-kit` peut causer des problèmes de chargement
+   - Remplacé par un placeholder dans `AnalysisScreen`
+   - Sera réactivé après configuration complète
+
+### 🚀 Relancer l'application
+
+```bash
+# Nettoyer le cache
+npm start -- --clear
+
+# Ou redémarrer complètement
+rm -rf node_modules
+npm install
+npm start -- --clear
+```
+
+### 📱 Vérifications réseau
+
+1. **Même réseau Wi-Fi**
+   - Votre ordinateur et téléphone doivent être sur le même réseau
+   - Désactivez les VPN si actifs
+
+2. **Pare-feu**
+   - Autorisez Expo dans votre pare-feu
+   - Port 8081 doit être ouvert
+
+3. **Mode tunnel (si problème réseau)**
+   ```bash
+   npm start -- --tunnel
+   ```
+   ⚠️ Plus lent mais fonctionne même avec des réseaux différents
+
+### 🔍 Diagnostic
+
+Si le problème persiste, vérifiez :
+
+```bash
+# 1. Vérifier la connexion
+ping 192.168.1.132
+
+# 2. Vérifier que Metro tourne
+# Vous devriez voir "Metro waiting on exp://..."
+
+# 3. Tester sur le web d'abord
+npm run web
+```
+
+### 📊 Réactiver les graphiques (plus tard)
+
+Une fois l'app fonctionnelle, pour réactiver les graphiques :
+
+1. Installer les dépendances natives :
+   ```bash
+   npx expo install react-native-svg
+   ```
+
+2. Dans `src/screens/AnalysisScreen.tsx` :
+   - Décommenter `import { PieChart } from 'react-native-chart-kit'`
+   - Remplacer le placeholder par `<PieChart ... />`
+
+3. Rebuild l'app
+
+### 🆘 Autres problèmes courants
+
+#### Erreur "Unable to resolve module"
+```bash
+npm start -- --clear
+```
+
+#### Erreur "Network request failed"
+- Vérifiez votre connexion Internet
+- Essayez le mode tunnel : `npm start -- --tunnel`
+
+#### L'app crash au démarrage
+- Vérifiez que Firebase est configuré dans `src/config/firebase.ts`
+- Regardez les logs dans le terminal
+
+#### "Expo Go" ne trouve pas l'app
+- Assurez-vous que les deux appareils sont sur le même réseau
+- Redémarrez Expo Go
+- Rescannez le QR code
+
+### 💡 Conseils
+
+1. **Première fois** : Utilisez `npm start -- --clear` pour un démarrage propre
+2. **Développement** : Le rechargement à chaud peut parfois causer des bugs, rechargez manuellement (secouer le téléphone > Reload)
+3. **Production** : Les graphiques fonctionneront mieux dans un build natif
+
+### 📞 Besoin d'aide ?
+
+Si le problème persiste :
+
+1. Vérifiez les logs dans le terminal
+2. Regardez les erreurs dans Expo Go (secouer > Show Dev Menu > Debug)
+3. Consultez la documentation Expo : https://docs.expo.dev/
+
+## ✅ Checklist de vérification
+
+- [ ] Dépendances mises à jour (`npx expo install --fix`)
+- [ ] Cache nettoyé (`npm start -- --clear`)
+- [ ] Même réseau Wi-Fi
+- [ ] Pare-feu autorise Expo
+- [ ] Firebase configuré (si vous testez l'auth)
+- [ ] QR code scanné avec Expo Go (pas l'appareil photo)
