Zero Sheep - A cognitive shuffle sleep app for overthinking nights

by•
This is a sleep support app inspired by the cognitive shuffle technique. Instead of counting sheep, you listen to random, unrelated words and gently imagine them one by one. The goal is not to force sleep, but to help shift attention away from repetitive thoughts and mental loops that often appear at bedtime. Features: • Word audio playback • Multiple voices • Adjustable playback speed • Optional ambient sounds • Background playback with the screen locked • Sleep timer

Hi Product Hunt 👋 I'm Kengo, an indie developer from Japan. I often struggled with nights when I wasn't particularly anxious, but my thoughts simply wouldn't stop. The more I tried to sleep, the more my mind kept jumping from one topic to another. While researching sleep techniques, I discovered Cognitive Shuffle — a method that uses unrelated words and mental imagery to gently interrupt repetitive thinking. I wanted something simple that I could use without staring at a screen, so I built Zero Sheep. Instead of counting sheep, the app slowly plays random words and lets you casually imagine them one by one. I'd love to hear your feedback: • Have you tried Cognitive Shuffle before? • What helps when your thoughts won't stop at night? • What features would make this app more useful? Thanks for checking it out!
