Somnia: Sleep Sounds & Relax on Windows Pc

Fall asleep to rain, white noise, and ocean waves — sleep sounds mixed exactly the way you like, to help you relax and reach deep sleep. Somnia is an offline ambient sound mixer with a gentle fade-out sleep timer, and it's yours for one small payment. No subscription, ever. 🌙

Layer up to three seamless loops into a single soundscape, then let the sleep timer ease the volume down to silence and stop on its own. Nothing plays till morning, and nothing drains your battery overnight. You get the whole noise palette too — white, pink, brown, and even green noise, the deep low-frequency wash few apps bother to include.

Pay once, keep it forever
One purchase unlocks everything — no auto-renewing subscription, no recurring charge, no ads. Other sleep sound apps bill you every year. Somnia? Once. Forever.

Mix up to three sounds
Stack heavy rain over a box fan over ocean waves, each at its own volume. White noise for focus, rain and nature sounds for sleep, a fan to mask the room — your mix, your balance for relaxation.

Fade-out sleep timer
Pick a preset from 15 minutes to 2 hours, or any length up to 8 hours. The sound drifts away gently instead of cutting off, so you fall asleep before it ever stops.

Overnight bedside mode
Rest your phone on the nightstand and dim the screen to a soft amber glow — a calm bedside night light that won't keep you awake, with the fade-out sleep timer right there so you can start the night without leaving the dark.

Gentle wake alarm
Wake to a soundscape that fades in slowly, instead of a jarring buzzer.

Save your favorite mixes
Build the blend that works for you — rain and thunder, white noise and a fan, ocean and a campfire — and bring it back with one tap.

Bedtime reminders
A quiet nudge to wind down at the time you choose.

Eighteen seamless loops 🌧️
Rain, heavy rain, rain on a tent, rain with a thunderstorm, ocean waves, waves on rocks, a mountain stream, a calm stream, white noise, brown noise, pink noise, green noise, a box fan, a crackling fireplace, a forest, birds, a quiet cafe, and a purring cat.

Works fully offline ✈️
Every sound is built into the app. No streaming, no buffering, no account — airplane mode, the mountains, anywhere. Open it and press play.

Private by design
No account, no sign-up, no profile. Nothing you listen to leaves your device, and there are no ads or third-party advertising trackers — just anonymous, aggregate diagnostics to fix bugs.

Great as a white noise machine for deep sleep, a bedside night light for the nightstand, a focus tool for work and study, and calming nature sounds for relaxation and stress relief. Download Somnia and drift off tonight.
