Can't switch off a racing mind at night? Wisp is a sleep-onset tool for overthinkers โ€” not another meditation app. Lie down, press play, and close your eyes. Wisp reads you a gentle, paced stream of unrelated single words โ€” a river, a kettle, a feather โ€” in a calm, human-quality voice. Picturing each one gives your busy mind something soft to follow instead of the worry loop, so sleep can come on its own. Nothing to learn, nothing to clear from your mind. HOW IT WORKS โ€” THE COGNITIVE SHUFFLE Wisp is built on the cognitive shuffle, a sleep-onset technique created by a cognitive scientist. Random, calming images are close to how a mind naturally behaves as it falls asleep โ€” so following them helps you let go. WHY WISP IS DIFFERENT - Real, human-quality voices โ€” never robotic text-to-speech. - A large library of words that doesn't repeat night after night. - Layer in calming ambient sound and mix it to taste. - A quiet, true-black night screen made for the dark. - No accounts to fill, no streaks to chase, no pressure. FOR THE NIGHTS YOUR MIND WON'T QUIET Whether it's overthinking, a racing mind, or just trouble winding down, Wisp gives your attention a gentle place to rest. WAKE TO A FRESH PAGE Mornings show a gentle rhythm of your wind-down habit โ€” never a sleep score, never a judgment. SIMPLE AND HONEST A free voice and ambient sound, every night. A subscription unlocks the full voice and sound library โ€” monthly or yearly, cancel anytime. We don't make medical claims or promise perfect sleep; we give your mind a kinder way to wind down. Sleep well. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula

For nights when your thoughts will not stop. Kotonemu reads out unrelated words, one at a time, in a gentle voice. Apple. Umbrella. Mailbox. While you picture words that have nothing to do with each other, your brain cannot keep a chain of reasoning going. As that effort loosens, sleep arrives on its own. It is a direct implementation of the method known as cognitive shuffle. WHAT MAKES IT DIFFERENT - A different order every night. 600 words, chosen so that related ones never follow each other. No two words from the same category, and no two starting with the same sound. You will not learn the sequence. - It fades as it goes. Volume, the gap between words, and the reading speed all ease off over the session, so it keeps reaching you if you are still awake without waking you once you are not. BUILT NOT TO DISTURB - No ads. Nothing interrupts you. - No network. It works in airplane mode. - The screen dims by itself, and you can hide the words entirely. - Optional rain or ocean underneath. THE VOICE All 600 words were recorded by a voice actor. Nothing is synthesised. PRICING The app is free. All 600 words and the 10, 15 and 30 minute sessions stay free forever. For seven days you can also use every session length. After that, a single payment unlocks the 60 minute, 90 minute and unlimited sessions if you want them. There is no subscription. This app is not a medical device and is not intended to diagnose or treat insomnia. If sleeplessness persists, please consult a doctor.
