Listen to the unrelated words of Cognitive Shuffle in a gentle voice and gaze idly at the night view unfolding beyond the raindrops.

Let go of the anxiety of "I have to fall asleep quickly" and return to a time of doing nothing by the rainy window.

There are no scores, records, or goals to achieve.

Choose your favorite scenery, watch the raindrops gently flow, and trace the fog as you please.

Even if you hear words, there's no need to memorize them or follow their meaning. Just freely imagine the scene.

【Looking Beyond the Window】

We've prepared 28 different night views from 20 countries around the world, including Tokyo, Kyoto, Paris, and New York.

Choose a window view that suits your mood tonight from cityscapes, beaches, lakes and rivers, forests and mountains.

You can simply gaze at the view without touching the screen, or let the scenery automatically switch.

[Trace the raindrops on the window]

The fog will clear only in the area where you move your finger, and the scenery beyond the window will quietly become visible.

The traced area doesn't disappear immediately, but slowly returns to fog over time.

The raindrops flow briefly, stop, and then slowly start moving again.

Touch at your own comfortable pace, without rushing or setting a specific goal.

Turning on "Fog with breath" in the settings allows you to clear the fog from the entire window by blowing on the screen.

You will only be asked for microphone permission when using this function. The audio is instantly detected within the device and is not recorded, saved, or transmitted externally.

[Listen to cognitive shuffle]

Pressing "Sleep" will read out short, unrelated words one by one.

There's no need to deeply consider the meaning of the words. Freely imagine whatever comes to mind, and let go when the next word arrives.

Choose between a gentle female voice and a calming male voice to suit your mood that night.


[Matching Rain Sounds and Music to Tonight]

This app includes seven sleep-inducing background music tracks, primarily featuring rain sounds and quiet piano.

You can adjust the volume of the rain sounds, music, and voices to your preference.

You can set an end timer, and playback continues even when you close the screen.

On sleepless nights or nights when you have trouble falling asleep due to worries, you can simply let the sound play without looking at the screen.


[For Those Interested in Sleep Topics]

For those who are concerned about sleep deprivation, sleep insufficiency, or sleep debt, perhaps sparked by topics like "30 minutes of sleep a day," "short sleepers," or "microsleep."

This app doesn't offer methods to cut down on sleep time.

It's a time to take a breather by a rainy window and quietly relax before going to bed at night, or before a nap or power nap.

【7-Day Free Trial and One-Time Purchase】

For 7 days from the first time you start "Rest," you can use all features for free.

Using only the free period will not result in automatic billing or the start of a subscription.

After the 7-day trial ends, a one-time purchase of 580 yen is required to start playback again.

Playback started during the free period will not stop prematurely due to the expiration date.

Purchase information can be restored using the same Google Play account.

On sleepless nights, have time to relax without having to accomplish anything on the screen.

Simply relax by the window on a rainy day.
