2. Memory Management: Optimize terminal buffer memory usage
3. Battery Life: Minimize background network activity
4. Smooth Scrolling: Maintain 60fps scrolling in terminal output

Implementation Timeline

Phase 1 (Week 1-2)

• Light mode support
• SSH key management UI
• iPad keyboard shortcuts

Phase 2 (Week 3-4)

• Advanced keyboard features
• Push notifications
• Basic file editor

Phase 3 (Week 5-6)

• Polish and testing

Conclusion

The iOS app has a strong foundation with excellent mobile-specific features like haptics, recording, and native UI patterns. The main gaps are in theme support, SSH key management, and some advanced terminal features. By implementing the recommended features while maintaining iOS design principles, VibeTunnel can achieve feature parity while providing a superior mobile experience.

The focus should be on making the app feel completely native while matching the web's functionality. Features like biometric authentication, widgets, and Shortcuts integration could make the iOS app exceed the web version in mobile-specific scenarios.
