About this app

On sleepless nights, close your eyes and simply listen to words that don't seem to connect in meaning. If you don't try to understand the meaning, your swirling thoughts will quietly unravel. Before you know it, you're asleep.

"Orange," "balloon," "harbor." These unrelated words continue slowly in a calm voice. Simply get into bed, press "start," and close your eyes. This method is based on a technique called "cognitive shuffle sleep."

■ Why do thoughts stop?
On sleepless nights, one thought leads to another, and your mind becomes a never-ending cycle. By following the sequence of unrelated words, this chain is broken. Your mind becomes quiet, making it easier to fall asleep.

■ Voice
A calm voice slowly reads the words. The volume of all words is consistent, so there are no sudden loud noises. You can also adjust the interval between words to "slow."

■ Screen Remains Dark
The screen is dim with warm tones, reducing blue light. Text is displayed at a whisper-like faintness, so it won't be dazzling in a dark bedroom.

■ Stopping Time
You can choose a "Stopping Time" of 15, 30, or 60 minutes, and the sound will slowly decrease and automatically stop. It's designed not to continue ringing after you fall asleep.

■ No Unnecessary Steps
No account registration is required. Everything, including audio, is handled within the device without any communication. No data is collected.

■ Pricing
Text-only use is always free. The text-to-speech "Voice" feature is free for 14 days, and if you wish to continue, it's a one-time purchase of ¥120. There are no monthly or additional charges.
