SleepNest Offline Sounds

Build a quieter space with SleepNest Offline Sounds, a local sleep sound mixer designed for rest, focus, reading, and meditation. Choose an original soundscape or shape your own mix from ten procedurally generated layers. Rain, ocean, fire, wind, night ambience, fan, stream, brown noise, clock, and night train can each be adjusted independently. The sound engine runs on your device, so core playback does not need a network connection or downloaded audio files. CALM PRESETS Start quickly with Night Rain, Coastal Rest, Moonlit Camp, Deep Cocoon, Clear Focus, or Midnight Rail. Every preset opens in the mixer, where you remain in control of each layer. YOUR MIX, YOUR LEVELS Use individual volume sliders to combine only the sounds you want. Changes reach the active soundscape immediately, without restarting playback. LISTENING TIMER Choose 15, 30, 60, or 120 minutes, enter a custom duration from 1 to 720 minutes, or play without a timer. Timed playback stops automatically when the selected duration ends. BACKGROUND PLAYBACK Your soundscape can continue while you use another app or turn away from the SleepNest screen. Android may ask for notification permission so playback controls can remain available while the foreground audio service is active. SAVE SOUNDSCAPES LOCALLY Name and save as many mixes as you need. Load a saved mix later or delete it from local storage. No account or cloud sync is required. SleepNest creates synthetic ambient textures rather than using field recordings. Results may sound different across speakers and headphones. Network access is used by the advertising SDK when an ad is requested; the procedural sound engine and saved mixes remain on-device.
