Sleep music that actually puts you to sleep.

Aviana is free to use. Sleep sounds, the smart alarm, sleep tracking, saved mixes, and bedtime reminders are free. The ready-made spatial mixes, curated and community, play spatially for everyone at no extra cost. Advanced features are part of the premium subscription: custom AI affirmations beyond your first five, the adaptive layer, and offline downloads. No ads. No third-party trackers in either the app or this marketing site. We do collect de-identified usage events on our own server (no PII, retained 90 days) so we can fix what breaks. De-identified sleep research: with your opt-in, readings with no name or email help us study what improves sleep. 90-day retention, never sold.

No. Aviana does not require sign-up, email, or password. The app generates a random 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. If you opt in to sleep research, Aviana sends de-identified readings (heart rate, breathing, inferred sleep stage) keyed to a random ID with no name or email; it defaults to off, 90-day retention, never sold.

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. Subscribe via the 'get notified' link below to be told the moment the App Store and Play Store builds are live.

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, and Suunto through Apple Health and Android Health Connect: those apps already write heart rate and sleep data into your phone's health store, and that is exactly where Aviana reads. If your wearable writes to those sources, Aviana sees it without a separate integration, and nothing routes through a third-party aggregator.
