About EVOA
Your period is a vital sign. When it goes missing, your body is telling you something, and you deserve to actually understand what. EVOA is the learning app for active women with irregular or missing periods. Through short, science-backed lessons, EVOA teaches you why your cycle is affected by your training, your nutrition, and your stress levels and what you can do about it without giving up the things you love. Whether your period has stopped completely, become unpredictable, or you just want to understand your body better before things get worse, EVOA gives you the knowledge to take it seriously and act on it. What you'll find inside: — 20+ structured lessons covering your cycle, hormones, nutrition, training, and recovery — Science-backed content written by a qualified PT and nutrition coach, based on peer-reviewed scientific studies which are transparently shared with you — A selected expert directory featuring practitioners who understand LEA, RED-S, and hormonal imbalances, and won't dismiss you or default to the pill EVOA educates. It never diagnoses. But it gives you the knowledge to ask better questions, make informed decisions, and find the right support. Your cycle. Your training. Both.
