Noxa: White Noise Sleep Sounds

Hephae LLC

About this app

Noxa is a sleep & focus soundscape mixer built differently: every sound is generated
on your device — rain, ocean, stream, wind, fireplace, brown/pink/white noise, and
soft tonal pads. No licensed meditation library, no "unlock the
library" trap. The whole catalog is free.

Most sleep apps hide their real content behind a subscription and nag you
with upsells. Noxa doesn't.
- No subscription. Ever. The entire sound catalog + mixer + presets are free.
- No account, no sign-up, no cloud. Local-first — your mixes stay on your device.
- Layered mixer — blend rain + fireplace + brown noise at your own volumes.
- Curated presets — Deep Sleep, Rainy Night, Focus Flow, Ocean Calm, Campfire.
- Sleep timer — sounds fade out gently so you drift off, then they stop. Free.
- Works offline. Background playback when the screen locks.

WHY NOXA IS DIFFERENT:
• Subscription apps gate their library → Noxa's whole catalog is included.
• Others bury features behind premium → Noxa's mixer is open by default.
• No upsells → Noxa is one calm screen, no nags.

Fall asleep to sound that's yours. Download Noxa.
