Dozio: Sleep Sounds
A cozy corner for sleep
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Eight cozy scenes. Two-second start. No subscription jail. Sleep without setup.
Calm is a wellness department store. Dozio is the warm corner you can fall asleep in.
Eight hand-mixed scenes. Tap one. Two seconds later, you're drifting off.
No 12-week courses. No mood tracking. No 300-sound directory making you choose. Just sounds, the way it should be.
WHY DOZIO IS DIFFERENT
• Warm lo-fi design that feels like a candlelit room — not a hospital.
• Curated scenes (not raw sound libraries). Each scene is a pre-mixed experience with four sound layers.
• Mix your own night — drag the layer sliders to taste. More rain, less thunder. More crickets, less owl.
• Two-second time-to-play. Tap, drift, sleep.
• A bedtime reminder that's gentle, not naggy.
• Plays through the silent switch, just like your music app.
• Background-safe — keep it playing while you check messages, read, then sleep.
THE 8 FREE SCENES
• Gentle Rain — soft rain on a tin roof, raindrops on a puddle.
• Ocean Waves — waves rolling in, salt air, far-off seagulls.
• Forest Night — crickets, leaves rustling, an owl in the distance.
• Fireplace — crackling logs and a cozy howl outside the window.
• White Noise — white, pink, and brown noise to mask any distraction.
• Thunderstorm — heavy rain and rolling thunder.
• Cafe Ambience — warm chatter, an espresso machine, lo-fi tones.
• River Stream — flowing water, morning birds, soft grass wind.
SLEEP TIMER, DONE RIGHT
The 15-minute timer covers the typical time to fall asleep without overplaying. You can switch to 30 or 60 minutes — or watch a quick opt-in ad to unlock unlimited playback for the night. The last 30 seconds gently fade out so the silence doesn't wake you.
NO TRACKING
No analytics SDK. No personal account. No email at signup. Nothing leaves your device except the ad identifier used for the bottom banner — and that's resettable from your phone's privacy settings.
LANGUAGES
13 languages: English, Español, 中文, Português, Français, Deutsch, Italiano, 日本語, 한국어, Русский, Bahasa Indonesia, Tiếng Việt, Türkçe.
Dozio is independently built by Adelie Studio, a one-person indie studio. Goodnight.
