## What is Sleep Static?

Sleep Static is a quiet mixer for background sound. Layer generated noise, pure tones and recorded textures, give every layer its own volume, set a timer, and save the mixes you like.

GENERATED NOISE
• White, pink and brown noise, generated continuously on your device instead of a short recorded loop.

RECORDED TEXTURES
• Steady rain, rain on a metal roof, rain on a window, rain in the forest, rain on water, wind, wind in the trees, ocean, lake shore, stream, waterfall, fire, fan, train and singing bowl: 15 field recordings edited into seamless loops.
• Tap play next to any sound in the Sound library to preview it before you add it.

PURE TONES
• Sine or triangle tones from 20 to 1000 Hz in 1 Hz steps.
• Quick picks: 174, 285, 396, 417, 432, 528, 639, 741, 852 and 963 Hz. The numbers describe the sound; they make no health promise.
• Add several tones at once, as long as each waveform and frequency pair is different.

MIX UP TO FIVE LAYERS
• A vertical fader per layer, plus mute, edit and remove.
• Keep playing in the background and control playback from the Lock Screen.
• Optionally play alongside music or podcasts from other apps.

TIMER
• 15, 30, 45 or 60 minutes, 8 hours, a custom 1–720 minutes, or no timer.
• Optional gentle fade-out over the final 30 seconds.
• The timer counts listening time: pausing also pauses the countdown.

SAVED MIXES
• Save as many mixes as you like, with their timer settings. Rename, update or delete them any time.
• Mixes stay on this device. No account, no sign-in, no sync.

PRIVATE AND OFFLINE
• Works without an internet connection.
• No ads, no analytics and no tracking.
• Available in 15 languages: English, Tiếng Việt, 简体中文, 繁體中文, Español, Português (Brasil), Français, Deutsch, Русский, Türkçe, Bahasa Indonesia, हिन्दी, العربية, 日本語, 한국어, with dark and light themes.

FREE
Every feature is free. If Sleep Static is useful to you, Settings has an optional "Buy me a coffee" tip. It is a voluntary one-time purchase that you can repeat, and it unlocks nothing.

For listening and personal comfort. Not a medical device and no medical claims.
