Sleep music that actually puts you to sleep.

Core sleep sounds are free. The smart alarm, sleep tracking, saved mixes, offline mode, and bedtime reminders are free. The first two custom AI affirmations per device are free; further generations will eventually be part of a paid tier (timing not set). No ads. No third-party trackers in either the app or this marketing site. We do collect anonymous usage events on our own server (no PII, retained 90 days) so we can fix what breaks.

No. Aviana does not require sign-up, email, or password. The app generates an anonymous device identifier the first time it runs and uses that to scope your saved mixes, settings, and affirmation history. Reinstalling the app generates a new identifier, so previously generated custom affirmations will not be visible after a reinstall today; we are adding cross-device persistence in a future update.

No. The adaptive sound layer and the smart alarm are better when they can read your heart rate, sleep stages, and HRV — but every health integration is opt-in. You can use Aviana as a pure sound + AI affirmations app without granting any health permissions, and the catalog plays exactly the same.

Aviana is in pre-launch on both stores. While we finish review, the full app is available as a Progressive Web App at app.aviana.life — it works on iPhone, Android, iPad, Mac, and PC, supports offline mode, background audio, and Apple Health / Health Connect on supported browsers.

No. The prompt you type lives in memory only for the duration of the request. We use it to query the AI, hash it for a cache key (so re-asking the same prompt re-serves the same audio without re-billing), and then drop it. The generated audio file is kept on our CDN so you can replay it; the prompt that produced it is not.

Yes. Aviana has a built-in offline mode. From Settings → Offline access you can download the full sound catalog (about 500 MB total) or specific tracks. Once cached, audio plays without any network. Custom AI affirmations require network at generation time, but once generated they play offline too.

Partially. Without a wearable, Aviana still varies texture across the night on a schedule — denser at sleep onset, sparser through what should be deep sleep, gentle landings near morning. With a connected wearable (Apple Watch, Whoop, Oura, Polar, Coros, Suunto) the adaptation is real-time: density follows your actual heart rate and detected stage rather than the clock.

Apple Watch directly via WatchConnectivity. Whoop, Oura, Polar, Coros, Suunto via Terra, the wearable-API aggregator we route through. Apple Health and Android Health Connect cover any sleep-stage data the device's OS exposes — so if your wearable already writes to those sources, Aviana sees it without a separate integration.
