## What is Wonder Sleep?

Every night, millions of people around the world struggle to fall asleep. Wonder Sleep uses science-backed methods to help you rediscover how to rest.


### Sleep Tracking — Your Personal Sleep Recorder

Based on your sleep stage data, automatically records deep sleep, light sleep, and awake time, giving you a clear picture of every night's rest at a glance. No wearable devices needed — simply place your phone beside your pillow, and Wonder Sleep accurately captures your sleep rhythm. The moment you wake up, you'll see a complete sleep report that clearly shows how long you slept and how well you rested.


### White Noise — Turn the World to Silent Mode

Curated high-quality ambient soundscapes, from rainfall to ocean waves, from forest breezes to crackling fireplaces — a rich sound library to suit every preference. Effectively masks disruptive noises like city traffic and noisy neighbors, helping you fall asleep faster within a cocoon of sound while significantly extending your deep sleep duration. Supports timed shutdown and background playback, so you can drift off without a worry.


### Bedtime Stories — A Pillow Book for Grown-Ups

Specially crafted soothing audio stories for adults, featuring content ranging from healing travel journals and warm everyday essays to light sci-fi tales — no intense plots or startling twists. With gentle narration and perfectly paired background sounds, these stories calm the day's accumulated racing thoughts, relax every nerve, and guide you naturally into dreamland. Each story runs 20–30 minutes — just enough to carry you from awake to asleep.


### Sleep Analysis — Turning Data into the Key to Better Sleep

More than just recording — it's deep interpretation. Through intuitive charts and weekly trend reports, Wonder Sleep helps you discover: Does sleeping in on weekends really help? How much did late-night phone use affect your deep sleep? Which white noise works best for you? The system regularly generates personalized insight reports, allowing you to understand your body step by step and make truly effective adjustments.


### Sleep Courses — Sleep Better, with Expert Guidance

A series of courses co-created by professional sleep consultants and psychologists, covering practical topics such as quick sleep induction techniques, anxiety management, and sleep routine reconstruction. Each lesson takes just 10–15 minutes and can be completed in spare moments, paired with daily mini-exercises that gradually reshape your sleep mindset and habits. By the time you complete the program, you'll have mastered the ability to take control of your own sleep.
