Our Client, a leading provider of high-end audio systems, needed to complement their advanced hardware with a powerful and intuitive user experience. The goal was to develop a cross-platform mobile application that would allow end-users to fully control and customize their audio systems remotely from their smartphones.
Developex took on the full-cycle development of this mobile application, from UI/UX design to final implementation and Q&A.

We built a single, adaptable application using Qt that delivered a seamless user experience across both iOS and Android environments. This allowed users to control playback, manage settings, and switch between audio sources directly from their smartphones.
The app was engineered for smooth, reliable communication with the hardware via Bluetooth LE, handling the complex NMEA 2000 protocol. This integration allowed the app to serve as a natural and powerful remote control.
Designed with a focus on usability, the app offered an intuitive interface for navigation, playlist management, and device configuration. This significantly enhanced accessibility for end-users, providing a convenient alternative to physical remotes or displays.
