YOUR HEALTH, IN CONTEXT Your body gives you signals every day through your sleep, activity, heart rate, recovery, nutrition and habits. Ottavia brings them together, understands them in the context of your life, and helps you know what to do next. Wake up knowing what your body needs today. Know how to fuel before a run and recover afterwards. Understand why your sleep changed. See when to push and when recovery should come first. And when you have a question, just ask. EXPERT KNOWLEDGE, APPLIED TO YOU Ottavia isn’t another AI health coach. The expertise comes from people. Choose trusted experts across nutrition, sleep, performance, endurance, recovery, women’s health, mobility and more. Ottavia uses AI to connect their knowledge with your health signals, goals, habits and daily context, making human expertise personal and useful in your everyday life. Your experts aren’t another source of information to read. Their knowledge becomes part of how Ottavia guides you. YOUR DAY, GUIDED BY YOUR EXPERTS Every morning, Ottavia looks at your latest signals, your goals and what’s ahead, then applies your experts’ knowledge to build clear guidance for your day. Training, meals, hydration, recovery and sleep come together in one personalized plan. And because real life rarely follows a perfect schedule, your guidance adapts as your day changes. See what matters today, why it matters and what to do about it. GUIDANCE AT THE RIGHT MOMENT Good guidance is most useful when it arrives at the right time. Ottavia brings your experts’ knowledge into your day, from what to eat before training and when to fuel during a long run to how to recover afterwards or when to start winding down for better sleep. Less checking. Less guessing. Clear actions when they matter. ASK ANYTHING. GET YOUR EXPERTS’ PERSPECTIVE. Have a question about your sleep, training, nutrition or recovery? Just ask. Ottavia understands your health signals, goals, habits and what’s happening in your day, then applies the knowledge of the experts you’ve chosen to your specific situation. Ask why you didn’t sleep well last night, what to eat before your run, whether today is a good day to push harder, or what could be affecting your recovery. You’re not getting a generic AI answer. You’re getting trusted human expertise, made relevant to you through Ottavia. UNDERSTAND YOUR FOOD Take a photo of your meal or simply tell Ottavia what you ate. Understand calories, protein, carbohydrates, fats and other nutritional information, then go beyond the numbers. Ottavia applies your nutrition experts’ knowledge to help you understand how that meal fits your goals, training and the rest of your day. See whether you’re fueling enough, what may be missing and what to eat next. UNDERSTAND WHAT’S CHANGING A single score rarely tells the whole story. Ottavia brings your signals together over time and interprets them with the knowledge of your chosen experts. Daily, sleep and post-workout reports help you understand patterns across activity, nutrition, training and recovery. See what changed, what may have influenced it and what deserves your attention next. ALL YOUR SIGNALS, TOGETHER Connect supported health and fitness services and combine that data with the context only you can provide, including your meals, goals, routines, preferences and how you feel. Depending on your connected services, Ottavia can work with sleep, activities and workouts, heart rate, recovery, daily movement, body metrics and other available health signals. BUILT WITH PRIVACY AT ITS CORE Your health information is deeply personal. Ottavia is designed to minimize the connection between your identity and your health information and give you control over the data you choose to share and connect. Ottavia is not a substitute for professional medical advice, diagnosis or treatment. Always consult a qualified healthcare professional about your health or medical concerns.
