## Description

Six generative sleep scenes — audio that never plays the same way twice, visuals that never loop. iPhone, iPad, Apple TV. One purchase, no subscription.

Drift to sleep with six generative ambient scenes.
Audio crossfades from random offsets so no two nights sound the same — the way real rain sounds different every time you hear it. Visuals render live in Metal, not from a video loop.

iPhone, iPad, and Apple TV. One purchase. No subscription.
No ads. No account. No cross-app tracking.

THE SCENES
• Thunderstorm — distant rumbles, sheet rain on a tin roof. Free, forever.
• Frequencies — a sound bath for sleep. Warm, resonant tones from the sound-therapy tradition.
• Fireplace — crackling embers and the slow breath of a fire on a winter night.
• Ocean Night — long swells under a moonlit sky.
• Aurora Night — wandering aurora over a quiet pine canopy, rain through the leaves.
• Deep Space — pure pink, green, or brown noise synthesis, slow harmonics, the hum at the edge of hearing.

AUDIO THAT NEVER REPEATS
Each scene's audio is built from layered samples that crossfade at random offsets — three independent layers in indefinite, never-repeating combinations. The Deep Space scene goes further: pure noise synthesis, no samples at all.

VISUALS THAT NEVER LOOP
Every frame is generated live in Metal from noise functions and procedural math — not played back from a video file. Rain, embers, water crests, star twinkle, aurora brightness — all driven in real time. You can leave a scene playing all night and never catch a repeat.

TUNE EVERY SCENE
Each scene exposes 8–12 sliders. Save custom mixes. Share them with anyone via a short code that recreates the exact scene on their device.

PLAYS ALL NIGHT
Background audio on iPhone runs locked-screen-off without draining your battery. A sleep timer with a soft fade lets you set it and drift. iCloud privately syncs your presets across devices.

DESIGNED FOR APPLE TV
Hero scenes render full-bleed on the largest screen in your house.
One Family Sharing purchase covers everyone.

PRIVACY
Sleep Sine has no servers we operate and no accounts — your presets sync privately through your own iCloud. The only data collected is anonymous usage and crash diagnostics, through Google Firebase, to improve the app — no ads, no advertising ID, no cross-app tracking, no personal data. It's off by default in the EU, UK, and Switzerland, and you can turn it off anytime in About & Privacy.

ONE-TIME PURCHASE
That's it. Family Sharing enabled.
