Your calendar age tells you how long you have lived. BioAI helps you explore what your current routines may be building next. Complete a short lifestyle assessment across sleep, movement, nutrition, recovery, and risk exposure. BioAI combines your answers into a transparent wellness-age estimate with a confidence range, ranked lifestyle drivers, and an actionable first-week plan. WHAT YOU GET • An estimated BioAge and range • Your strongest current lifestyle driver • A focused first-week action plan • Weekly check-ins and estimate trends • A source-linked science library OPTIONAL SELFIE, PRIVATE BY DESIGN Add an optional selfie moment to the scan animation. On-device Vision only checks whether one clear face is present. The image is not uploaded, stored, or used in your estimate, and you can continue without a photo. BioAI is a wellness and educational tool. Its estimates are based on self-reported lifestyle inputs, are not a medical diagnosis, and should not replace advice from a qualified health professional.
