Quiet a racing mind in 3 minutes. Tap once — then close the phone and sleep.
A 3-minute calm session for the nights you can't fall asleep, or wake up at 3 AM and can't drift back off. A gentle wave of light expands with your breathing, soft ambient sound fills the background, and the screen fades — so you can naturally close the phone and rest.
■ How it works
・One tap to start, three minutes to end
・A wave of light moves with your breath
・The screen dims gradually and fades out
・When it ends, just close the phone and sleep
■ Two modes
・Bedtime — a standard calm pace for winding down
・Night — slower and quieter, for returning to sleep after waking
■ 5 ambient sounds
・Ocean Wave
・Rain
・Brown Noise
・Campfire
・Silent
■ Also included
・Afterglow — keep the sound going for 15, 30, or 60 minutes after a session
・Record — the nights you spent calmly, kept in a simple calendar on this device only
・Long-press the app icon to start a session right away
・Eight languages: Japanese, English, Traditional Chinese, Simplified Chinese, Korean, German, French, Spanish
■ Who this is for
・You lie in bed with thoughts that won't stop
・You wake at 3 AM and can't fall back asleep
・You can't put the phone down before sleep
・Late-night screen time keeps your mind too alert to sleep
・You're tired of sleep apps that pressure you to keep a streak
・You want a simple sleep app
One screen. One session. That's it.
