Sethoro reads your day — body, behavior, environment, mind — and generates your night: an adaptive soundscape and a wind-down story written just for you. Then it checks your watch to see what worked. Every night gets smarter.
Sleep apps play the same content to everyone and never check whether it worked. Sethoro closes the loop.
Heart rate, HRV and sleep debt from your watch. Screen time and late caffeine from your phone. Bedroom light and noise from its sensors. A 10-second check-in for what's on your mind. No manual tracking.
A soundscape that starts just under your evening heart rate and slows as you do. A story written tonight, from your actual day — specific at first, dissolving into calm, silent once you're asleep.
Sleep onset, deep, REM — measured by the wearable you already own. What worked stays. What didn't gets replaced. Tonight beats last night.
Most apps optimize minutes listened. Sethoro succeeds when it can finally shut up.
Tempo anchored to your heart rate, easing down as you drift — then fading to complete silence once sleep holds.
An AI narration built from your day — "the release is out of your hands now" — that lets the day end before you do.
Wakes you during light sleep inside your window, with a rising soundscape. The hard alarm is sacred — it always fires.
"Slower tempo + rain: asleep 9 minutes faster, deep sleep +12%." See what we tried, what your watch showed, what's next.
"Coffee after 8pm costs you ~20 minutes." Nudges from your own patterns — before the mistake, not after.
The entire night session runs offline, on your phone. Raw health data never leaves the device. Ever.
Melatonin fades. Rain videos loop. Static apps repeat.
Sethoro learns.
