For the press Ninety.: press kit

Ninety. is a one-tap control for the moments when the world is too much: in Control Center on iPhone, or Quick Settings on Android. One tap plays ninety seconds of brown noise that gently pulses with a slow breath rhythm, and ends on its own. Made quietly by sthreelabs as the second app in the Sensory & Focus chapter: small tools for difficult moments.

02.One-paragraph editorial copy

Ninety. is a single-tap control, in Control Center on iPhone or Quick Settings on Android, that plays ninety seconds of brown noise gently paced to your breath, then ends on its own. Designed for moments of sensory overwhelm (a noisy office, a difficult phone call, a too-bright supermarket): it offers a brief audio cover and an optional breath rhythm to sync with, then quietly steps away. No streaks, no notifications, no microphone access, no subscriptions. Made by sthreelabs as the second app in their Sensory & Focus chapter.

07.Brand reference

Name and styling

The app's name is written Ninety. with a trailing period: the period is part of the brand mark, like Yahoo!'s exclamation point. Always include it in standalone uses. In flowing prose where the period would create awkward double-punctuation, prefer rephrasing to land "Ninety." at the end of a thought.

Studio name

The studio is written sthreelabs, lowercase, one word. Not SthreeLabs, not S3 Labs, not three labs.

08.Background: what makes Ninety. notable

Procedural audio. Ninety. generates brown noise live on-device via AVAudioEngine source nodes (Brownian motion + 30 Hz high-pass filter + breath LFO modulation). No bundled audio files. The breath envelope is computed sample-accurately as the audio plays: the rhythm isn't a recording, it's math.
iOS 18 Control Center widget. Built on Apple's new ControlWidget + AppIntentControlConfiguration APIs. The pace selector (Slow / Quick) is a per-widget-instance configuration, set once when adding the widget, persisted by iOS, no in-app settings screen.
Anti-engagement by construction. The session ends on its own at ninety seconds. There is no streak counter, no total-time-played metric, no "today's sessions" badge, no leaderboard. The product makes itself less useful the more useful it is.
Audience-finds-itself. Ninety. never uses clinical language about sensory overwhelm, ADHD, autism, or anxiety. The product is described entirely on the experience it serves (a moment of overwhelm) and the audience that needs it locates itself.
First in a chapter. Ninety. is the first of six planned apps in the sthreelabs Sensory & Focus chapter: A Visible Hour, One Thing, Cue, Settle, and Quiet Hour will follow. Each addresses a different sensory or focus moment with the same studio voice and a shared warm-brutalist visual register.
