Free
Educational, not medical advice. Subscription happens in the Ottavia app.
How does it work?
Connect your wearable or log your sleep, meals and workouts. Each morning Ottavia reads your night and your day, applies Dr. Prather'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 Dr. Prather's subscription?
Their published methods and research, applied by Ottavia to your own sleep, training and meals every day. You see where their 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 Tuesday night.
Is this medical advice?
No. Dr. Prather guides and educates through Ottavia. They never diagnose or prescribe.
Do I talk to Dr. Prather directly?
No. Ottavia has read their published work and applies it inside your guidance. Your questions go to Ottavia; their 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. AI runs on anonymized context, separated from your identity; your personal and health data is never shared with any AI provider, and never sold.
Does Dr. Prather 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.
