A small app for the moments that needed one.

What it is, in plain terms.

Stillee is an evidence-based mindfulness app. It includes a free panic flow that opens with one tap. A dedicated 3 AM mode written for the middle of the night, separate from bedtime. A curated NSDR library at three lengths. A breathing room with patterns named for the evidence they draw on. And a set of multi-week programs that build on each other, including an eight-week course built on the MBSR curriculum.

It runs on iOS. Android is planned.

What it is not.

It is not therapy. It does not diagnose or treat clinical conditions. It is not a thousand-track library to browse for an hour. It is not a famous-voice celebrity guide. It is not a streak counter dressed up as a wellness product.

Where the evidence comes from.

The practices in Stillee are grounded in clinical and experimental evidence that we can name. The 8-Week Mindfulness Course is built on the MBSR curriculum developed by Jon Kabat-Zinn in 1979, which has the strongest evidence base in the consumer mindfulness category. The panic flow uses cyclic sighing as the default rhythm, the technique that outperformed mindfulness on mood and respiratory rate in a 2023 Stanford randomized controlled trial. The 3 AM mode draws on the CBT-I literature, specifically cognitive shuffle and paradoxical intention. The NSDR library carries Yoga Nidra structure with the modern framing.

Where the evidence is mixed, we say so. Where it is strong, we cite the primary source. The Journal carries the full long-form on each.

How we research the Journal.

Every article starts from the primary literature rather than from a search for something to say. We read the trials and the reviews, we quote the figures they actually report, and we link every source at the foot of the page so you can check the work yourself. Where the evidence is thin or mixed, the article says so in as many words.

Each piece opens with the answer in two sentences. If that is all you need, stop there. The sections underneath are for the reader who wants the detail, and the references are for the reader who wants to argue with us. Articles carry a review date as well as a publication date, and when we revise one, that date moves.

The guide you hear in the app is a synthetic voice, generated with text to speech from scripts we write. We are not going to pretend otherwise. It is one voice across the whole catalog, chosen so that the sound stays familiar at the moment you least want a surprise. The Sound Bath shelf is the exception in the other direction: those are recorded instruments and human voices, and nothing on it is synthesized.

Who it is for.

Adults who want a calm, evidence-grounded companion for sleep, anxiety, and panic, without a thousand-track catalog or a famous-voice celebrity guide. The panic flow is for anyone who needs it tonight, paying or not.

Who builds it.

Stillee is made by Competente Nuvem - Lda, a small studio in Portugal. The voice across the catalog is one voice, by design.
