Brian Eno is well-represented in iOS. His other apps like Bloom, Trope and Air invite listeners to touch the screen to make their own composition. Reflection ($30.99) is different, there is no interaction for the listener. The interface has three buttons: a pause button, a sleep timer, and AirPlay. Reflection produces endless permutations of Eno’s 2017 album, an hour and five minute long title track.
“Just calling it an app is akin to saying Falling Water is just a building,” writes one app store reviewer. “I would not call this an app,” agrees another, “Between the music and visuals it’s more like sonic architecture.” The visuals consist of slowly morphing rectangles that only seem to change in the split second you look away from the screen.
People mix the terms UI and UX together. UX is tricky because it doesn’t refer to any one thing. Interface design, visual styling, code performance, uptime, and feature set all contribute to the user’s “experience.” Books on UX further complicate matters by including research methods and development methodologies. All of this makes the field confusing for people who want to understand the fundamentals.
That’s why I avoid teaching the term ’UX.’ It means too many things to too many different people. Instead I focus on individual skills. Once you understand the individual skills, you can assemble them into a composite system without blurring them together. For software design, the core skill among all user-facing concerns is user interface design.
