Everything in Stilli
Sound designed to help your nervous system settle — slow, soft, and predictable, with nothing to learn and nothing tracking you.
🌅
Four calming modes
Morning Calm, Anxiety Relief, Pre-Sleep Wind-Down, and Deep Sleep — each tuned to a different moment of the day.
🌧️
Nature sound layers
Mix in rain, ocean, wind, fire, and forest underneath the music, to whatever depth feels right.
♾️
Endless variations
A fresh ambient mix every session, so it never loops into something you've already tuned out.
🌙
Sleep timer & offline
Drift off with a gentle fade-out, anywhere — no signal or streaming required.
🔬
Backed by research
Slow, sub-60 BPM instrumental music is shown to ease cortisol, the body's main stress hormone.
🔒
No tracking, ever
No accounts, no analytics, no ads. Stilli doesn't collect or sell your data — full stop.
