HushLoop: sleep sounds and a nursery nightlight in one app

HushLoop is Knox Studios’ on-device mixer for colored noise plus a dimmable nightlight — presets, 3-band EQ, and WAV export without a required account.

Key takeaways

Layer up to three sounds with independent gain instead of a single looping track.
The nightlight is a true-black canvas with a soft radial glow, not a bright dashboard.
Presets and EQ stay on the device; there is no required HushLoop cloud account.
Export mixes to WAV when you want the audio outside the app.

Bedtime should not be three apps and a harsh screen

HushLoop by Knox Studios puts a sleep sound mixer and a nursery nightlight in one muted interface. Mix brown noise, heartbeats, and other layers, then keep the room glow in amber or peach without blasting blue-white UI.

Built to stay quiet

Three-layer mixer with per-track gain.
3-band EQ and locally saved presets.
On-device audio engine — mixes are not a cloud playlist.
Optional WAV render for a single sound or a full blend.
