4. Complete incomplete features (Wallet, Filters, Promo Codes)
5. Migrate to Kotlin (gradual migration)
6. Implement CI/CD pipeline
7. Add comprehensive testing (Unit + UI + Integration)

Business Impact: Medium (Long-term sustainability)

Conclusion¶

The Android client application is functionally complete for its core use case (telemedicine video consultations) with 82% of features fully implemented. However, it carries significant technical debt and security vulnerabilities that require immediate attention.

Key Strengths:
- ✅ Core features (auth, booking, video calls) work well
- ✅ Comprehensive feature set
- ✅ Bilingual support (EN/AR)

Key Weaknesses:
- ⚠️ Outdated dependencies (security risk)
- ⚠️ Poor code structure (god objects, large classes)
- ⚠️ Security vulnerabilities (hardcoded credentials, plain text passwords)
- ⚠️ Limited testability (no unit tests)

Recommended Approach:
- Phase 1: Security fixes
- Phase 2: Code quality & UX
- Phase 3: Architecture modernization
