Ambient sleep sounds, offline forever
White noise, rain, and ocean — mixed your way.
Somnia layers up to three loops — rain, a box fan, ocean waves — into one seamless soundscape, then a gentle fade-out timer drifts you off and stops on its own. All offline.
For sleep, focus, study, and relaxation.

Questions
Good to know
- Does Somnia work without internet?
- Yes. Every sound is built into the app, so it works fully offline — on a plane, in the mountains, anywhere.
- Is it really a one-time purchase?
- Yes. One purchase and Somnia is yours forever — no subscription, and nothing auto-renews.
- Will it drain my battery overnight?
- No. The fade-out timer lowers the volume to silence and stops playback on its own, so nothing runs until morning.
- How many sounds can I mix at once?
- Up to three at once, each with its own volume.
- Do you track what I listen to?
- No. There are no accounts and nothing you play leaves your device; we keep only anonymous, aggregate diagnostics.
