Designed for the dark.
Personalized for you.
From discovery to your own soundscape — every screen is intentional.
Discover what makes
you tingle.
Swipe through 80+ curated ASMR sounds and long-form YouTube sessions. Each tap and skip teaches Stillwater exactly what your nervous system responds to.
Sounds you love go straight to your library. Ones you skip won't resurface for 90 days. Every interaction refines your personal Tingle Profile — automatically.
Your sounds.
Your rules.
Layer up to 10 sounds at once — or 9 sounds plus a YouTube or TikTok video playing underneath. Dial in the volume and speed of each individually, then save the whole thing as your mix.
Fine-tune every layer until it feels exactly right, then save it as a named mix. When you need it most — before sleep, during focus, on a hard day — it's one tap away in My Sounds.
Your library.
Always ready.
Every sound you've saved and every mix you've built lives here. One tap loads your whole soundscape — exactly how you left it — for when you need stillness fast.
Save full YouTube playlists and tap to load them directly into the Mixer. Rename mixes inline, browse your saved videos, and keep your discoveries organized your way.
Your brain,
mapped.
Every swipe, save, and skip refines your Tingle Profile — a living map of what calms your nervous system, across 10 trigger dimensions.
Track your sessions, see your listening patterns, and watch your profile sharpen. No two are alike.
