COMING SOONThe future of personalized health
Health isn't built in a day. It's built through years of small decisions, changing bodies, and evolving needs.
Built to grow with you.
Every day adds another piece to your health story. Over time, Ottavia connects your wearables, biomarkers, blood tests, symptoms, habits, and life events to uncover patterns unique to you.
Built by women for women
Women's health isn't a niche. From menstrual health and pregnancy to perimenopause and healthy aging, Ottavia is built to understand the biological changes that shape women's lives.
Your personal board of experts
No single expert has every answer. Build a trusted team of experts that grows with you, bringing together different perspectives for every stage of your life.
How does it work?
Connect your wearable or log your sleep, meals and workouts. Each morning Ottavia reads your night and your day, applies Danny Dreyer's methods where they fit, and gives you one clear plan. Ask anything during the day; the answers use your own data.
What do I get with Danny Dreyer's subscription?
Danny Dreyer's published method, applied by Ottavia to your own sleep, training and meals every day. You see where that work shaped a message, every time.
Why can't I get this from ChatGPT?
ChatGPT answers from general knowledge and forgets you between questions. Ottavia reasons from your actual data, every day, and applies a named expert's published method with attribution. It is not advice in general; it is about your own Tuesday.
Is this medical advice?
No. Danny Dreyer guides and educates through Ottavia, and never diagnoses or prescribes.
Do I talk to Danny Dreyer directly?
No. Ottavia has read Danny Dreyer's published work and applies it inside your guidance. Your questions go to Ottavia; that thinking comes back in the answer, attributed.
What happens to my health data?
Your data stays in your Ottavia account and is used only to guide you. The third-party AI services Ottavia uses never learn who you are: they see the health context needed to answer you, never your name or contact details. Your data is never sold, never used to train AI models, and is deleted from those services when you delete your account.
Does Danny Dreyer see my data?
No. Experts contribute their methods to Ottavia; they never see individual users or their data.
Do I need a wearable?
Ottavia works best with Apple Watch, Garmin or Google Health. You can also log sleep, meals and workouts yourself.
What does it cost, and can I cancel?
The price is shown clearly before you subscribe. Manage or cancel anytime in the Experts hub; you keep access until the end of the period you paid for.
