Lilt · C1 concept — clickable prototype (sample data)

A mobile mockup of Concept C1, the “calm-versions” adaptive music app: real songs re-arranged by AI, adapting to your heart-rate variability in real time. Built for moderated think-aloud usability sessions (n = 5–8).

This is a click-through mock, not a working app. No wearables actually connect, no audio plays, and no payment is processed. All names, readings and metrics belong to a fake “Test User” and are for testing reactions to the flow and concept only.
