Sleep sound mixer
Sleep sound mixer for iPhone: ten channels, each with its own volume
Restful lets you shape a sleep soundscape on iPhone or iPad, with a separate volume control for every channel. It is part of the released App, not a web-only demo.
Choose from ocean, stream, rain, thunder, wind, campfire, crickets, singing bowl, cafe and white noise. Raise one sound, lower another, or leave a channel silent; the App remembers your mix for next time.

How it works
How to mix rain, thunder and other sleep sounds
Open sleep sounds
Choose the mixer rather than a full-length nature or city track. The ten named channels are available together, not as separate subscriptions.
Set each level
Move the slider for each channel independently. For example, keep rain prominent and thunder quiet. The mixer remembers your last balance.
Set the audio timer
Choose 10, 15, 20, or 30 minutes if you want playback to stop automatically. These are sound timer options, not the length of a nap or an overnight recording.
The sounds
A soundscape you shape
In the App, each of ten channels has its own volume slider. Audio plays only when you choose it; the web page never requests microphone access.
The sounds play inside the Restful app on iPhone and iPad. Nothing is downloaded or played on this page.

Adjust the volume of each sound separately
The mixer works as listening audio. You do not need a wearable, an account, or a nightly chart to use the sound controls.
The App also has four full-length nature tracks and four night-city ambiences. The ten mixer channels are a separate set of adjustable elements.
The sounds are part of the App; this website does not play them.
Limits
Before you start: the sound timer is 10, 15, 20 or 30 minutes
- The audio timer is limited to 10, 15, 20, or 30 minutes; do not treat it as an unlimited overnight sound promise.
- The mixer’s noise channel is white noise; it has no brown or pink noise channel.
- This page has no audio previews. The sounds play inside the App on iPhone and iPad.
- If you also turn on the optional sound curve for the night, the App’s own sounds can be heard by its microphone and influence that night’s curve.
A direct answer
Can I hear the same mix on this website?
Not yet. Sound previews aren’t available on the website; the sounds play inside the App.
