About this app

Fall asleep to rain, white noise, and ocean waves — mixed exactly the way you like. 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.

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 for sleep, a fan to mask the room — your mix, your balance.

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.

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 sleep, a focus tool for work and study, and a calm soundscape for naps. Download Somnia and drift off tonight.
