Turn down the world. Tune in to the night. MoonVale is an offline ambient sound app designed for quiet evenings, relaxation, and bedtime. No account, no complicated setup—just choose a scene, put down your phone, and let the atmosphere unfold. IMMERSIVE NIGHTTIME SCENES Step into a rainy cabin, a moonlit coast, a warm fireplace, a night train, a deep forest, or a sleep pod drifting through space. Every sound is stored on your device, so you can listen anytime—even without an internet connection. CREATE YOUR OWN SOUNDSCAPE Blend rain, ocean waves, wind, fire, and other ambient layers. Adjust each sound individually, save your favorite combinations, and return to them with a single tap. BUILD A BEDTIME ROUTINE Create a sequence of scenes and choose how long each one should play. MoonVale moves through your routine automatically, using gentle crossfades to make every transition feel natural. GENTLE FADE-OUT TIMER Set a timer from 5 to 90 minutes. Instead of stopping suddenly, the sound gradually fades into silence. Background playback and Lock Screen controls let you keep listening without leaving the app open. REVIEW LAST NIGHT See which scenes played and how long you listened. Your history stays on your device and reflects playback time only—not actual sleep duration. PRIVATE BY DESIGN No account required. No activity tracking. No personal data collection. Core sounds work completely offline. The free version includes a selection of scenes and essential mixing features. Upgrade once to unlock the complete sound library, premium layers, custom bedtime routines, and sleep fade features. No subscription required. MoonVale is designed to create a relaxing environment. It does not provide medical advice, sleep diagnosis, or treatment.
