Noiso: Sleep Sounds & Timer

Calm offline sleep sounds with 7 ambient presets, background playback, and a timer that fades out softly before silence.

Noiso is a minimal sleep-sound app for iPhone.

Choose from 7 built-in ambient presets inspired by forest air, ocean waves, rainfall, snow, steam, fjords, and desert wind. The app is designed to stay calm and low-stimulation: one screen, one large play button, simple preset switching, and no extra setup.

Why people use Noiso:

• 7 bundled ambient presets
• Sleep timer with infinity, 30m, 1h, and 2h options
• Soft fade-out before playback stops
• Background playback and lock screen controls
• Works offline
• No ads, subscriptions, purchases, or account system

Noiso is intentionally simple. Open the app, swipe between presets, tap play, and leave the sound running in the background while the rest of the night routine stays quiet.
