Customer-Ready Thesis
Most white-noise apps are static loops, even when the listener is still wired or already drifting off. This product uses wearable heart-rate signals to adjust tempo, texture, and volume over time, helping the soundscape match the user's state instead of forcing the user to pick another preset. The first user is someone who already wears an Apple Watch or Fitbit at night and wants a calmer wind-down routine.
Who it is for: People who use wearables, sleep aids, focus playlists, and bedtime routines but want sound that responds to them.
