Free. No ads. No tracking.
Fall asleep with sound, science, and silence.
Aviana is a sleep-sounds app engineered around peer-reviewed acoustic research. Works offline. Costs nothing.
Why it works
Three commitments behind every sound in Aviana.
-
Curated sleep sounds
Pink and brown noise, rain on canvas, low-frequency drones, and live-recorded singing bowls. Every track is mastered to a -20 LUFS sleep target so the volume you set at 9pm still feels right at 3am.
-
Adaptive to your night
A subtle adaptive layer adjusts the texture of the soundscape over the night — denser early, sparser through deep sleep, gentle bell-tone landings near morning. No abrupt transitions, no surprises.
-
Research-backed by design
Pink-noise bursts phase-locked to slow oscillations (Papalambros 2017). Sound masking that reduces nocturnal arousals (Stanchina 2005). Every choice points to a paper, not a vibe.
Get Aviana
Install once. Sleep better tonight.
The native apps unlock background playback, lock-screen controls, and a small set of nightstand-friendly extras the web build can't reach. The web build covers everything else.
On a desktop? Both stores work — open Aviana on the phone you actually sleep next to.
