Based on the "Cognitive Shuffle" method developed by Dr. Luc Beaudoin, a cognitive scientist at Simon Fraser University, this app is designed to help you drift off by scrambling your logical thoughts. When your brain is busy solving problems or worrying, it stays awake. By visualizing a sequence of unrelated images—like "Sunfish," "Crocodile," or "Sweater"—you trigger the brain's natural transition into sleep mode. [Features] Human Narrations: Natural, soothing voices recorded by professional voice actors, not robotic text-to-speech. Bi-lingual Support: Features both Japanese and English narrators. Customizable Rhythms: Adjust repeat counts and silent intervals to match your personal sleep pace. Sleep Timer: Automatically stops playback so you can sleep soundly. Word Management: Toggle specific words on or off to create your perfect shuffle list.
