How it works

Three quiet steps to day sleep.

Play, layer, recover — without ads, without sudden blasts, without a loop point.

  1. 01

    After shift. One tap.

    Open the app and tap Deep Sleep: a brown-noise bed with soft rain, a sleep timer and a gentle fade — ready for a noisy daytime room.

Inside the app

A sleep sounds app built around your rota.

Sound, mixer, shift profiles and calm AI — one place after nights.

  • Infinite sounds, no loops

    White, pink, brown and green noise plus rain, ocean, fan, AC, wind, thunder and fireplace — generated live on your phone. No looping MP3 library, no gap when the track restarts.

  • Mixer and sleep timer

    Layer sounds, save favorites, and set a 15, 30, 45, 60 or 90-minute timer — or all day. Playback fades out softly instead of stopping dead.

  • Shift profiles

    Fixed nights, rotating, early or on-call. One-tap day-sleep and recovery-nap logging so you can see which sleep windows you protect.

  • AI sleep helper

    Describe your rota and what helps after a night shift — get a playable mix and a short wind-down routine. Not medical advice.

  • Works offline

    Because sound is generated instead of streamed, it starts instantly and keeps running with no signal — hospital basements included.

  • No ads. Ever.

    Nothing interrupts, autoplays or wakes you at 2 p.m. Guest mode keeps profiles and logs on your device.

After shift

Day-sleep calm. Ready when you are.

Popular uses

One sound engine, many daytime rooms.

Day-sleep setup

Soft starts. Steady sound.

Every play soft-starts over two seconds and the timer fades out instead of cutting off. Peak output stays controlled — blackout curtains, a quieter room, and a mix that holds through daylight.

FAQ

Questions about white noise and day sleep, answered.

Is ShiftSleep a white noise app for night-shift workers?

Yes. ShiftSleep AI is a white noise and sleep sounds app built for people who work nights and sleep during the day. It generates white, brown, pink and green noise plus rain, fan, AC and ocean on your phone, with a mixer, a sleep timer with fade-out, and shift profiles for fixed nights, rotating, early and on-call schedules.

What is the difference between white, brown and pink noise?

They differ in how energy is spread across frequencies. White noise is even and bright, good for masking voices and daytime chatter. Brown noise puts most of its energy in the low end, a deep rumble that covers traffic and footsteps through a wall. Pink noise sits between the two: warmer than white, lighter than brown. You can layer them in the mixer.

Do the sounds loop?

No. Every sound is generated live by a procedural audio engine, so there is no loop point, no seam and no gap. That is also why the download is small and why it works offline.

Does it work offline?

Yes. Sounds, the mixer, the timer, shift profiles and sleep logging all work with no signal. Only the AI sleep helper needs a connection.

What is free and what is Premium?

Free includes core sounds such as white, pink and brown noise, a two-layer mixer, the sleep timer and one shift profile. Premium unlocks the full sound catalog, a four-layer mixer, the AI sleep helper and unlimited saved mixes, billed weekly, monthly or yearly through Apple or Google.

Is ShiftSleep medical advice?

No. ShiftSleep AI supports rest and routine with sound and simple logging. It is not medical advice and does not diagnose or treat sleep disorders. If your sleep problems persist, talk to a clinician.

Nights on. Days off.
