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.
