SleepStim, a Private Night Watcher for Your Phone
A browser-based sleep listener that detects snoring, coughing, movement, room noise, and possible sleep depth without sending sound away from the phone.
Field notes
SleepStim organizes its overnight session around a small set of live estimates: breathing rate, sleep depth, room noise in dBFS, snoring intensity, disruptions, and interventions. Its operating instructions are unusually concrete: keep the phone plugged in, disable Low Power Mode, leave the screen on, and expect listening to stop when the phone locks. The page also includes an alarm with a nine-minute snooze and presents sleep depth as a sound-based guess rather than a medical reading.
