Duskdial: Sleep Sound Mixer

About this app

Tap a sound and go to sleep. Duskdial plays rain, fan, ocean and true white, pink and brown noise all night with your screen locked, without a single ad. Turn a dial to mix up to eight sounds, set a timer that fades out gently, and dim everything to a deep red that will not wake you. In the morning, the playback log shows exactly how your night went.

Sound that keeps going
- Loops are seamless, with no clicks or gaps at the seam.
- Keeps playing with the screen locked and the app in the background.
- Pauses for a call and picks up again when it ends.
- Pauses when headphones or Bluetooth drop, so it never blasts the speaker at 3 AM (you can turn this off).
- Uses no mobile data. It works in airplane mode.

The playback log
Every night is recorded on your phone: when sound started, when it stopped, why it stopped, and any interruptions it recovered from. If something cut out, you will know.

18 sounds, all free
White, pink, brown, grey and green noise, box fan, cabin hum, surf, drizzle, rain on a roof, rain on a window, distant thunder, creek, night crickets, fireplace, wind in pines, night train and ocean shore. Mix up to eight at once, shape the tone of each one, and save as many mixes as you like.

A timer that behaves
Stop after a set time, or play until your wake time, with a slow fade at the end. The timer keeps time with the screen off.

Made for a dark room
True black and dim red night themes, big dials you can hit without looking, and a slow moving field that reflects your mix. Lock screen and Control Center controls work too.

Nothing to buy, nothing to tap by accident
No ads, no pop-ups, no subscription, no upgrade screens, no account and no email. Every sound and feature is free.

Duskdial plays sounds to mask noise. It does not track or measure sleep, and it is not a medical device.

What’s new

Improved sleep timer handling and fades when starting or changing a timer. Fixed the +15-minute action so it adds time to an active timer.
