Sleep Sine — ambient sleep scenes for iPhone, iPad, and Apple TV
Drift to sleep
ambient sleep scenes
Five generative scenes that play through the night — audio that never repeats, visuals that never loop. iPhone, iPad, Apple TV. One purchase, no subscription.
Never the same night twice
Each scene is created in the moment, so the rain you fall asleep to tonight isn't the rain you'll hear tomorrow. Drift into something fresh, every time.

Built for the way you sleep
Plays all night
Background audio continues through StandBy mode and the lock screen. The Now Playing pill on the Dynamic Island lets you pause without unlocking.
Sleep timer with a soft fade
Pick 15 to 90 minutes. The audio fades out gently over the last thirty seconds — no abrupt cut to silence.
Cross-device by design
Same app on iPhone, iPad, and Apple TV. Lock screen widgets, StandBy widgets, and Top Shelf branding all included.
Tune every layer
Dial rain density, lightning rate, mist, warmth, and per-layer audio mix. Save your favorites as named presets.
Share what works
Every preset becomes a 12-character code your friends can load on any device. Sent in seconds, restored exactly.
One-time purchase
One-time unlock for the full set of scenes, every future scene, and unlimited preset saving. No subscription. Family Sharing enabled.
Hands-free, eyes-closed control
You're already in bed. You don't want to open the app to skip a scene. Sleep Sine integrates with Siri, Home Screen widgets, and Shortcuts so the app responds to your voice, a tap from your lock screen, or an automation you set once and forget.
Just ask Siri
Works after the first launch — no Shortcuts setup, no permissions dance. The basics:
"Hey Siri, play Sleep Sine"
"Hey Siri, pause Sleep Sine"
"Hey Siri, next Sleep Sine scene"Home Screen controls
Add the Now Playing widget to your Home Screen and you get three tappable buttons next to the current scene — no need to open the app:
Wire it into bedtime
Every Sleep Sine action — play, pause, scene-by-name, sleep timer, sine code load — is a building block in the Shortcuts app. The power-user move:
- Open Shortcuts → Automation
- New Personal Automation → Sleep Focus turns on
- Add Action → Play Aurora Night on Sleep Sine
- Done — every time Sleep Focus starts, your scene plays.

Know your sine
Every configuration you save becomes a 12-character code — your sine. Tap one to load the exact scene we tuned, ready to drift to.
Questions
Is Sleep Sine free?
Thunderstorm is free forever — no time limit, no ads. Every other scene plays for a 2-minute preview each session. Unlock all of them (and every future scene) with a single one-time purchase — current pricing on the App Store. No subscription.
Does it play through the night?
Yes. Set a sleep timer from 15 to 90 minutes, or let it play until morning. Audio fades softly over the last 30 seconds — never a hard cut to silence.
Does it work on Apple TV?
Yes. Sleep Sine is one app that runs natively on iPhone, iPad, and Apple TV. Buy once, use it everywhere — Family Sharing is enabled.
Can I control Sleep Sine with Siri or from a widget?
Yes. Say "Play Sleep Sine," "Pause Sleep Sine," "Next Sleep Sine scene," or "Play Aurora Night on Sleep Sine" — Siri works after the first app launch, no setup. The Home Screen widget has tappable previous, play/pause, and next-scene controls (iOS 17+) so you never have to open the app to change anything. Every action is also a building block in the Shortcuts app for Personal Automations like "play Aurora Night when Sleep Focus starts." Full hands-free guide →
What's a "sine"?
Every saved scene becomes a 12-character code — your sine. Share it with a friend and they can load the exact same scene, dialed-in to the slider, on any device. See a few examples.
Does Sleep Sine collect any data?
No. There are no servers, no accounts, no analytics, and no third-party SDKs. Everything you do stays on your device. See the privacy policy for details.
Does it work offline?
Yes. Once installed, every scene plays offline forever. No internet required.
Will it keep my screen on?
On Apple TV the screen dims but never sleeps, so the scene plays through the night. On iPhone and iPad, audio continues through StandBy and the lock screen — pause from the Now Playing pill on the Dynamic Island without unlocking. More on how it works.
