Most cycle apps guess. Sophie checks. Sophie Premium starts with a 7-day free trial, then continues as a yearly or monthly subscription. 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, and she answers with your own calendar and charts: your fertile window, your best days, when to take an LH test. She remembers your history, your symptoms, and what you told her last week. • Wearables welcome, not required — works with Oura, WHOOP, Apple Watch, 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 data brokers, and no tracking you across other apps: to see which of our ads work, we count installs and purchases without your advertising ID. SOPHIE PREMIUM Everything described above is part of Sophie Premium, an auto-renewing subscription. • Start with a 7-day free trial. • Then $59.99 per year or $9.99 per month (US prices; local prices may differ). • Payment is charged to your Apple Account when the free trial ends. The subscription renews automatically unless you turn it off at least 24 hours before the end of the current period. Manage or cancel any time in your Apple Account settings. 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.

Your Apple Watch already knows how you are doing. WE-IN turns what it records into one thing you can act on: how long your body takes to settle after you eat. WHAT IT DOES Your Response curve A single line for your day, scored on the watch itself. No phone in your pocket, no waiting on a server, no signal needed. Settle time How many minutes a meal actually took to clear, measured against your own baseline rather than a nutrition table. Weekly Read The pattern across days: your calmest window, your most sensitive one, and what genuinely moved the number this week. History Every day you have worn the watch, and the month at a glance. Snap & Predict Photograph a plate and see the response WE-IN expects from it. ON YOUR WRIST The whole calculation runs on your Apple Watch. Add the complication to your watch face and your Response is there when you raise your wrist. Rising and settling alerts arrive on the watch, so you are told when something is worth acting on rather than having to go and look. YOUR FIRST THREE DAYS ARE FREE WE-IN is free for three days, counted from the first time you open it. No card is needed to start. After three days WE-IN needs a subscription to continue. Your readings stay in Apple Health either way, so subscribing later picks up where you left off rather than starting from nothing. SUBSCRIPTION WE-IN Premium — 9.99 USD per month, or 79.99 USD per year. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. Manage or cancel your subscription in your Apple Account settings. Privacy Policy: https://we-in.co/privacy Terms of Use: https://we-in.co/terms REQUIRES AN APPLE WATCH WE-IN reads heart rate, heart-rate variability, sleep and movement from Apple Health. An Apple Watch is required for it to have anything to read. WE-IN is a wellness app, not a medical device. It does not diagnose, treat, cure, prevent or monitor any condition, and it does not measure anything in your blood. Nothing it shows you is medical advice. If something concerns you about your health, speak to a doctor.
