Sophie vs Tending

Most cycle apps guess. Sophie checks. Sophie reads the nightly body temperature from your smart ring or watch and looks for the shift that proves ovulation actually happened — then adjusts everything downstream to where you really are in your cycle, not where a calendar assumed you'd be. WHAT MAKES SOPHIE DIFFERENT • Ovulation you can trust — confirmed from your own temperature data, not predicted from a 28-day average. Sophie learns your personal ovulation window from your confirmed cycles and gets sharper every month. • Your rhythm, measured — most apps assume a 14-day luteal phase. Sophie measures yours, because bodies don't read textbooks. • Sophie, your AI companion — ask her anything about what your body is doing. She remembers your history, your symptoms, and what you told her last week. • Wearables welcome, not required — works with Oura, Apple or Samsung Health, Ultrahuman, RingConn, and Fitbit, and works perfectly well on cycle dates you enter yourself. • The sky, too — your natal chart, lunar phases and daily astrology, woven in beside the biology for the days you want meaning as well as data. • Bring your partner — share exactly as much as you choose, and they get real guidance on how to show up for you. BUILT ON HONESTY Sophie tells you when she doesn't know. When your data is disturbed or the temperature shift hasn't arrived yet, she says so — instead of inventing certainty you might plan your life around. YOUR DATA IS YOURS We don't sell your data and we never will. No advertising SDKs, no data brokers, no tracking you across other apps. Sophie is a wellness and cycle-awareness app. It is not a contraceptive, is not a medical device, and does not diagnose or treat any condition.
