Sleep Mode: Deep Sleep Sounds

Your phone is now a sound machine. A good one.

Sleep Mode plays sound all night and does nothing else. One hundred sounds, a mixer that layers them, a timer that fades instead of stopping, and a wake-up that brightens instead of buzzing. The screen goes dark. The rain does not.

ONE HUNDRED SOUNDS, MASTERED FOR ALL-NIGHT LOOPING

Rain, wind, ocean, streams, crickets. Box fans, hair dryers, the hum of a refrigerator. Trains, highway drives, airplane cabins. Noise in white, pink, brown, green and grey. Womb and heartbeat. Music boxes playing public-domain lullabies, slowly. Three NASA mission recordings, for sleeping somewhere else entirely.

Every sound is loudness-matched and cut to loop without a seam. No gap, no click, no restart you can hear at 3am. All one hundred ship inside the app — nothing streams, nothing downloads later.

THE MIXER

Layer rain over a fan. Put the heartbeat underneath, quietly. Each layer gets its own fader, the mix gets a name, and tomorrow night it is one tap away. There is a "Same as last night" button, because that is the actual request at bedtime.

THE TIMER

Fifteen minutes or all night, nudged in fifteen-minute steps. When time runs out the sound fades over minutes — it does not cut to silence and wake you with the quiet.

GENTLE WAKE

Twenty minutes before your wake time, the sound starts to brighten. Birdsong on top, or simply louder, or nothing at all — your choice. No buzzing, ever. On iOS 26 and later, Sleep Mode can also schedule a real system alarm as a backstop, so you are woken even if playback stops overnight. On earlier versions of iOS the backstop option simply is not shown.

One honest note: Gentle Wake works because the app plays all night. If you force-quit it before bed, nothing is running to wake you. That is what the backstop alarm is for.

STATS WITHOUT FICTION

Sleep Mode keeps a log of your last seven nights: what played, and for how long. It knows when sound was playing. It does not know whether you were asleep, and it will not draw you a sleep-quality score invented from a wrist. The log lives on the phone and goes nowhere.

NO NETWORK

No account. No analytics. No network. The App Store call is the only one, and it's Apple's. Everything — all one hundred sounds, the mixer, the timer, the stats — works in airplane mode, at a cabin with no signal, and in the middle seat of a red-eye.

FROM THE MAKERS OF BABY MODE

Sleep Mode is the second app in the Mode family. The first one, Baby Mode, is for the other person in the house who won't sleep.

WHAT IT COSTS

Sleep Mode is free to download, and your first seven days are free too: listen to any sound for thirty seconds, then pick the six you want to keep for the week, with the timer and the mixer. No subscription needed. After seven days your six sounds lock unless you subscribe.

Sleep Mode Full unlocks all one hundred sounds: $2.99 per month after a 7-day free trial.

Payment is charged to your Apple Account when the trial ends. The subscription renews monthly unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel in Settings, under your name, in Subscriptions. Any unused part of the free trial is forfeited if you subscribe before it ends.
