Cycle-aware training app that adapts every daily workout to a woman's menstrual biology — building, protecting, or restoring based on where she is in her cycle, what her recovery signals say, and whether she's trying to conceive, on hormonal contraception, or pregnant. A deterministic engine pulls from 130+ trainer-authored templates and personalises intensity, weight, and pace; an AI layer writes the morning briefing, phase narrative, and adaptation reasoning in a warm, scientifically grounded voice that adjusts to each user's actual state rather than reciting generic phase scripts.
