*Core Feature Highlights



**Sound Wave Healing Cutting-Edge Technology: The innovative "Frequency Resonance Sleep Method" offers precise sound wave frequency bands ranging from 70Hz to 900Hz, covering brainwave patterns such as α waves (relaxation), θ waves (light sleep), and δ waves (deep sleep). Through a scientific blend of natural white noise, binaural beats, and ASMR sound effects, it rapidly guides the brain into an ideal state, relieving anxiety, calming emotions, and making falling asleep natural and effortless.



**AI Sleep Quality Analysis: It intelligently monitors the entire night's sleep cycle, accurately capturing data such as the durations of deep sleep/light sleep/wakefulness, the number of turnovers, and respiratory rate through the phone's microphone and accelerometer, generating visual sleep reports. Combined with the sleep research model from Harvard Medical School, it provides personalized improvement suggestions to help you gradually optimize your sleep habits.



**Emotional Healing Scene Library: Customizes sound wave solutions for different scenarios—over 20 themes including "Stress Release," "Pre-Exam Stress Reduction," "Morning Wake-Up," and "Meditation Focus," etc. Paired with breathing guidance and mindfulness meditation exercises, it creates an all-day emotional management toolkit.



**Minimalist Immersive Experience: Boasts an ad-free clean interface, an eye-protecting dark mode design, and supports background playback and timed shutdown. The innovative "Smart Fade-Out" technology allows you to fall asleep naturally amidst the gentle embrace of sound waves without worrying about being awakened.
