About this app

Mind racing at night? Stop overthinking sleep.

Shuffli is a drug-free sleep aid for insomnia and sleep anxiety — built around cognitive shuffling, the science-backed sleep technique taking over TikTok and backed by published research. A calm voice whispers random, neutral words one by one; you do light sleep visualization with each. It's a simple bedtime brain trick to fall asleep without medication. Before you know it, you're asleep — many users feel they're drifting off in seconds once it clicks.

Who it's for
- Anxious overthinkers who lie awake replaying the day
- People with racing thoughts, sleep anxiety, and worry-driven insomnia
- Anyone who wants to fall asleep fast without pills
- ADHD sleep and neurodivergent sleepers who need something faster than slow meditation

Why cognitive shuffling works

Insomnia is fueled by coherent, stimulating thought — worrying, planning, rehearsing. Cognitive shuffling replaces those loops with a rapid sequence of random, unrelated mental images. This mimics the natural micro-dream state at sleep onset, sending your brain a signal: it's safe to sleep now.

Most users report falling asleep within 5–15 minutes. Many don't finish the first sequence — a practical sleep hack when you need results tonight.

What makes Shuffli different

Unlike Calm, Headspace, or sleep sound apps, Shuffli doesn't ask you to learn meditation, listen to stories, or track your sleep. One sleep technique, one interaction, zero friction. Open the app, close your eyes, and listen.

The science

Developed by cognitive scientist Dr. Luc Beaudoin (Simon Fraser University). Tested in a 2016 study with 154 participants — as effective as CBT journaling for reducing presleep arousal. Covered by BBC Future, CNN Health, Fortune, and The Guardian.
