Neurosound: Voice of Universe

NeuroSound is an offline sound app for sleep, focus, meditation, and relaxation routines.

Play a sound on its own or combine up to four sounds in the mixer. The sleep timer gently lowers playback when time runs out. Lock-screen controls let you manage playback without reopening the app.

• Rain, forest, ocean, and other ambient sounds
• Binaural and single-frequency sound options
• Four-channel custom sound mixer
• Sleep timer
• Favourites and saved mixes
• 21 app languages
• No account, ads, or analytics SDK
• Fully offline operation

Binaural sounds and low-frequency tones need headphones; a phone speaker cannot reproduce them.

NeuroSound does not provide diagnosis, treatment, or medical outcome claims. Keep volume at a comfortable level.
