Sleep Aquarium creates a quiet aquarium-like soundscape for bedtime. Gentle water, soft tones, piano-like motifs, and small chimes drift slowly over time without becoming a short repeated loop. Start a timer, adjust the balance, and let the room settle into a darker, calmer aquarium. Features - Original generative water and music layers - 30-minute, 1-hour, and 2-hour timers - Controls for water, pad, motif, sparkle, BPM, variation, and sleep depth - Favorite settings for repeatable bedtime sessions - Background playback and Lock Screen controls - Plus unlocks a 10-hour timer, fullscreen aquarium, and three favorite slots All audio is original and generated inside the app. Sleep Aquarium does not use third-party music, video audio, game audio, or sample libraries. For bedtime routines, quiet reading, or a calm night background.
