About this app

SleepMix is a custom background audio mixer designed to support relaxation, deep sleep, and focus. Blend multiple ambient layers — rain, ocean waves, white noise, birdsong, and gentle instrumental melodies — into your own seamless sound mix, with individual volume control over every layer so you can build exactly the atmosphere you want.

Set a sleep timer anywhere from 15 minutes to 2 hours, and your mix fades out gently on its own — no falling asleep to a phone blasting sound all night. Everything keeps playing even when your screen is locked, so you can start your mix and put your phone down.

Beyond sleep, SleepMix includes a dedicated Study mode built around the Focus 25/5 method — 25 minutes of focus sound paired with a 5-minute break, repeating through a full session, so background sound works with your attention span instead of against it.

There's also a Kids section with its own calm, age-appropriate sound library for bedtime and quiet time, and a My Music tab where you can import your own audio files and mix them right alongside the built-in sound library.

Whether you're winding down for the night, settling a child into bedtime, or trying to stay focused through a work session, SleepMix adapts to how you actually use sound.

What’s new

Fixed a Study 25/5 timer issue: after a break ended while your phone was locked, the next focus period's timer used to keep running silently in the background. Now the next focus period's timer and music wait and start together the moment you reopen the app, so it always feels fresh and in sync. Give it a try and let us know how it feels!
