A warm AI companion and a quiet smart ring that turn your health signals into plain-language guidance.
Feather-light — you'll forget it's there.
A quiet, durable finish that goes with everything.
Days between charges, not hours.
Green-LED optical sensing, day and night.
Blood-oxygen and thermal trends while you sleep.
Deep, light and REM — measured honestly.
Optional — CoraVella also reads your Apple Watch or any HealthKit device.
Anyone can show you a chart. Cora reads the whole picture and tells you what it means for you today — in a sentence, not a spreadsheet.
Every reading is computed on your device. When you ask Cora, she only ever sees an aggregated summary — never your raw data.
A passive NFC emergency card — no battery, no app, no signal required. If you're ever unresponsive, any first responder can tap it with any phone and instantly see your critical details.
Your card is encoded on the device itself — the data never touches a server, so there's nothing stored to breach, sell, or track.
Hold your ring near the top…

No screens, no buzzing. Just a ring that listens while you live your day.
CoraVella is built for women across every life stage — so it never ages you out. It grows with you, and the story of your own body is yours to keep.
Your readings are computed on your phone. Cora only ever sees an aggregated summary — never your raw samples — and only with your consent.
This is wellness, not a data business. Your health signals are never sold, and there's nothing sitting on a server waiting to be breached.
US-built, US-hosted, on-device — your most personal data never leaves the country. A trust edge in a category that broke it.
