## What is Yozumi?

Yozumi is a low-stimulation sound app for returning to rest after a nighttime awakening. It deliberately keeps the clock off screen and uses a deep red-and-black interface so you can start a soundscape with as little interaction as possible.

・A night screen without the time
No large clock and no pressure to track every minute. Choose rain, noise, or a low ambient scene while keeping brightness and controls restrained.

・Sound that exits quietly
Play a wordless soundscape that gradually fades according to the session you select. Optional breathing cues and brief settling guidance are available when you want them.

Processing and history stay on device. A banner ad appears on supported screens; an optional one-time ad-removal option hides it.

Important: This app does not diagnose or treat sleep disorders. If sleep difficulties persist, consult a qualified healthcare professional. Do not use while driving or during tasks that require attention.
