HarmonyHub Music Education Interface: Mobile App Hardening and Relative Intonation Learning

HarmonyHub is an open-source platform designed to improve music education through interactive and technology-driven learning experiences. While the current application provides note practice and visualization features, its mobile experience requires improvements in performance, responsiveness, and stability. This project focuses on strengthening the mobile application by optimizing UI responsiveness, improving performance across devices, enhancing error handling, and introducing offline capabilities. In addition, it proposes the development of a relative intonation learning module built on top of the existing chromatic tuner, enabling users to practice pitch accuracy and musical intervals with real-time feedback. Key deliverables include a fully optimized mobile experience, a functional relative intonation training system with real-time feedback, improved audio processing performance, and cross-platform stability for iOS and Android devices. The final result will be a more robust, scalable, and pedagogically effective mobile application, making music learning more accessible, interactive, and engaging.
