Sensory & Focus · 02 Brown noise that breathes with you.

A Control Center widget for the moments when the world is too much. One tap, ninety seconds of brown noise that gently pulses with a slow breath rhythm, and it ends on its own.

01.What it does

• Tap the Ninety. control in Control Center, from any app, on any screen.
• Ninety seconds of brown noise fades in over three seconds.
• The noise pulses with a slow breath rhythm. Sync your own breathing to it as much, or as little, as you want.
• It fades out and ends on its own. No "stop" button to forget.
• Tap again partway through if you want to end early — the audio winds down gently, never cuts.

02.Two paces

Set the pace once when you add the widget to Control Center. Long-press the widget any time to switch.

• Slow. A 12-second cycle — about five breaths per minute. The rhythm associated with calm.
• Quick. An 8-second cycle — about seven and a half breaths per minute. Brisker, for getting back into focus.

03.The quiet posture

• No microphone access. No location access. No accounts. Nothing leaves your device.
• No streaks, no notifications, no analytics, no telemetry.
• One-time purchase. No subscriptions. No ads. No "Pro" tier.
• Music already playing dips while Ninety. plays, then returns to full volume on its own.

04.What it isn't

• Not a meditation course. No coach, no narration, no voice.
• Not a soundscape library. No browse-and-pick-a-vibe screen.
• Not a focus timer. The session is ninety seconds — short on purpose.
• Not a breathwork app. The breath rhythm is offered, not prescribed.
