Juvenai

Your biological age is not your age in years. Juvenai connects the signals your body produces every day: blood biomarkers, sleep, heart rate, heart rate variability, and physical activity. It turns that data into clear insights to help you understand your health, track your progress, and make more informed decisions. DISCOVER YOUR BIOLOGICAL AGE Upload a lab report and Juvenai extracts your biomarkers so you can review and adjust the detected values. Using this data, it estimates your biological age via PhenoAge, a scientific model based on blood biomarkers. Track your results over time and explore how they connect with your habits and health metrics. UNDERSTAND WHAT YOUR WEARABLE REVEALS Connect Apple Health to bring together your sleep metrics, heart rate, heart rate variability (HRV), and physical activity into a dashboard centered on your wellness and recovery. Juvenai only accesses authorized data and does not write information to Apple Health. TURN YOUR HABITS INTO PROGRESS Work in 14-day cycles, choose a set of concrete actions, and track your consistency. Juvenai helps you evaluate your adherence and use what you’ve learned to shape your next cycle. LOG YOUR MEALS WITH AI Snap photos of your meals or describe them using your voice. Juvenai estimates calories and macronutrients so you can better understand your nutrition without having to search for every food item manually. PROGRESS TOGETHER Share achievements, follow friends, and join teams that help you stay consistent. A community focused on habits and measurable progress, beyond appearances. YOUR DATA, UNDER YOUR CONTROL Your health information deserves special protection. Juvenai uses access controls to safeguard the data associated with your account. Review our privacy policy to learn how your data is stored, processed, and protected. YOUR JOURNEY TO LONGEVITY STARTS TODAY Available in English, Spanish, and Portuguese.
