YOUR personal AI fitness coach.
It runs a real coaching intake, builds an evidence-based program around your actual life, and adjusts as that life changes — a new baby, a busy week, an injury you're working around. Not a workout app. Not a chatbot with exercise knowledge. A coach that remembers.
Your health information stays private — encrypted under a key only you control, never shared, never sold.
