XJ Music Player

Mobile App

We built and shipped a mobile companion app for XJ Music, allowing listeners to tune in to XJ music channels.

The mobile app was designed to extend the core system beyond the workstation—putting adaptive, algorithmic music experiences into a pocket-sized surface. Our focus was shipping a coherent, production-quality app: defining the minimum lovable experience, building the client and its API surface, and operationalizing releases.

The app involved full-stack delivery: client application, backend API surface, authentication, audio hosting, and deployment via CI/CD pipelines.

Other XJ Music projects

The mobile app was one chapter in a longer XJ Music story—built on the patented engine that powers the system, wearing the brand identity we developed for all XJ touchpoints, promoted alongside physical merch at events, introduced to audiences through the promo content distribution system, playing the same kind of adaptive content heard in the demo scores, discussed in depth on the podcast, and eventually succeeded by the open-source workstation and runtime engine that opened the technology to everyone.
