## What is Moon?

Moon — Understand your sleep. Improve yourself.

Moon is the perfect app for anyone looking to wake up feeling energized, build a consistent schedule, and improve their sleep quality. Don't feel rested even after a full night's sleep? Want to know exactly what happens to your body while you rest? Moon analyzes your sleep phases, recovery quality, health metrics, and long-term trends. With Apple HealthKit integration, all data syncs automatically from your smartwatch or fitness tracker, making the analysis seamless and effortless.

KEY FEATURES:

- Sleep Stages & Score: Discover the exact breakdown of your deep, light, and REM sleep, as well as nighttime awakenings. Our high-precision algorithm calculates your personal Moon Sleep Score based on key recovery factors, helping you uncover the root causes of fatigue.
- Alarms & Tasks: Set reliable alarms tailored to your schedule. To help you wake up faster, you can use tasks: solve a math problem, complete a series of phone rotations, or read an affirmation, which gently activate your brain in the morning.
- Comparison & Trends: Track your health metrics over time. Analyze changes in heart rate variability (HRV), blood oxygen level (SpO2), and wrist temperature. Compare any sleep metrics across different days or weeks to visually track your progress and understand what truly affects your well-being.
- Morning Journal & Dreams: Don't let vivid dreams or great morning ideas fade away. Record your thoughts via voice or text immediately upon waking. Moon AI will help decode your dream plots, analyze your emotional tone, and save everything in a convenient journal.
- Sleep Goals & Streaks: Build healthy habits with our sleep goals system. Set your target sleep duration and track achievements on an interactive activity calendar. Maintain a daily sleep streak, use "freeze" logic to protect your progress during trips, and unlock unique achievement badges.
- Personalized Moon AI: Ask questions about your dreams or sleep quality and get science-backed recommendations. The upgraded AI assistant factors in your sleep goals and daytime habits (such as caffeine consumption) to provide tailored advice for optimizing your routine.
- Sleep Sounds: Create the perfect relaxing atmosphere. Fall asleep to soothing white noise, nature sounds, or ambient tracks. A built-in timer automatically turns off the audio once you are asleep.
- Challenges & Achievements: Stay motivated with friends. Participate in group sleep challenges, climb the leaderboards, earn unique badges for long-term consistency, and share stylish progress cards with one click.

### 5/5 — Stats galore!

*2025-12-26*

Love this app! It provides the specific sleep stage data that my Oura Ring app lacks. Being able to see the exact minutes of REM/Deep sleep, and the specific timestamps for when I’m awake (instead of just bars on a chart) makes a huge difference. Great UI and very insightful.

**Developer response:** Thank you so much for such a detailed and insightful review! I’m thrilled to hear that Moon is providing the level of clarity you were looking for.

My goal was exactly that — to move beyond abstract charts and give users concrete data, like exact minutes and timestamps, to truly understand their sleep patterns. Knowing that you find our UI helpful and superior in data presentation means a lot to me. Wishing you many more nights of deep, restful sleep!
