Nook
When your mind won't stop, tell Nook.
You talk — or type — and a calm voice answers in the moment, guiding you step by step: slow breaths, a gentle side-to-side calm, your own calm place. Until things settle.
How it works
Nothing to learn, nothing to prepare. Open the app, say how you are, and let yourself be carried.
Tell it how you are
By voice or keyboard, whatever feels easier. The voice listens and adapts to what you say — no scripts, no recordings.
It guides you, step by step
Slow breathing to bring your heart rate down, and a gentle bilateral rhythm — side to side — to let the body's tension go.
Build your calm place
A memory that does you good, a word that's yours alone. When you finish, you take it with you as a short audio made from your own session.
A look inside
Calm guides
The things you ask us, told slowly and without jargon.
Frequently asked questions
What is gentle bilateral stimulation?
You let your attention move slowly from side to side, left and right — a little like rocking, or a quiet walk. It's inspired by EMDR, a technique used in psychology, and here it helps the body loosen without having to think anything through. More on using it day to day →
Do I need an account?
No. Nook has no accounts: you open the app and begin. What you share stays yours and no one else's.
How much does it cost?
You get one free guided session every day, and the self-paced tools (breathing, bilateral calm) are always free. Nook Pro adds unlimited sessions and keeps your resources with you.
Does it help with sleep?
Yes — it's one of the best-loved uses. The wind-down mode lowers the rhythm with voice and breath until sleep arrives on its own. Here's how →
Is it therapy?
No. Nook is a daily calm practice, not treatment and not a substitute for professional help. If you're going through something heavy, please reach out to a professional — the app will also show you helplines for your country if it senses you need them.
A quiet minute is waiting for you.
To sleep better, to catch your breath before something nerve-wracking, or to give yourself a pause in the middle of the day.
