"still punk AF" i whisper to myself as i start my sleep app
sleepfuzz
A stompbox-styled noise machine for sleep and focus—big pedal energy, quiet nights.
Completely free to download and use. Optional SleepFuzz Pro is a one-time purchase—never a subscription. Pro adds themes, named custom presets, and manual control of white and brown noise. Every built-in preset is yours at no charge.

Pedal-inspired
Turn it on.
A metallic pedal face, rotary dials with haptics, a three-way noise switch, and a stomp-style power control. Audio is synthesized and processed in real time—continuous, smooth, and controllable—not short looping clips.
Playback continues in the background with Now Playing on the lock screen, Control Center, and Dynamic Island (even CarPlay!) on supported devices.
In the app
Everything within reach
Dials with haptics, a floating menu for themes and presets, and sleep timers that fade out gently. Nothing requires an account—ever.
Main screen
Stomp to start or stop, LED state, embossed preset title, and hammered metal finish with optional theme tint.
Quick menu
Themes, presets, and sleep timer—compact, haptic-backed, and out of the way until you need it.
Sleep timers
Wake time stops playback at a clock time you choose. Pro adds countdown presets with the same slow fade-out.
Every preset blends pink, white, and brown—you hear all of that for free. Fine-tuning the three-way noise switch yourself is unlimited on pink at no cost; selecting and adjusting white and brown on the switch unlocks with Pro.
Pink (manual)
Full control on the noise switch—level, tone, and the rest of the chain.
FreeWhite (manual)
Brighter, full-spectrum character when you drive the switch—Pro unlocks this mode.
SleepFuzz ProBrown (manual)
Deep, heavier low-end when you select brown on the switch—Pro unlocks this mode.
SleepFuzz ProSound design

Cosmetic
Themes

FAQ
Does audio keep playing when I lock my phone?
Yes. SleepFuzz uses background audio; playback can continue when the app is in the background or the device is locked, with standard iOS Now Playing controls.
What happens when the sleep timer ends?
Playback stops with a long, gentle fade—on the order of about a minute—so you are not jolted awake.
I bought Pro on another device—how do I restore?
Use Restore Purchase in the app’s upgrade flow. Pro is a non-consumable in-app purchase tied to your Apple ID.
Do I need an account or subscription?
No SleepFuzz account—there isn’t one. The app is free to use; SleepFuzz Pro is a one-time optional purchase through your Apple ID, not a subscription. Restores use Apple’s standard flow.
