The hardest week of your month shouldn't be a surprise. Sophie reads your nightly temperature and warns you before the luteal shift lands.
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.

Super easy to use and I love how personalized it feels compared to other cycle apps I’ve tried. The daily insights are actually helpful and easy to understand. Definitely keeping this one!
So cool

I was waiting for something that incorporates science, astrology, cycle tracking and advices. Love it!
Sophie knows your life better.
She now keeps a map of the people, places and projects you talk about — and how they connect to your cycle — so she remembers the whole story, not just last week.
Also fixed:
• Sophie no longer asks about an earlier cycle when your log already answers it
• Exporting a long chat is lighter on memory
• If we already sent your confirmation email, we say so instead of showing an error
• Coming back to the app after your phone slept is smoother
