Meet Wen your warm, private companion for understanding your cycle — predictions that learn you, beautiful home-screen widgets, and data that stays truly yours. Wen is your warm, private companion for understanding your body — one gentle, beautiful app for your whole cycle. Whether you're tracking your period, watching for your fertile window, or just want to feel more in tune with yourself, Wen makes it simple, calm, and genuinely yours. PREDICTIONS THAT LEARN YOU Wen doesn't just average a calendar. It studies your own history and quietly improves over time — so your period, ovulation, and fertile-window estimates get more personal the longer you use it. Every prediction comes with an honest confidence level, because your body isn't a formula. • Next period & cycle-day at a glance • Ovulation and fertile-window estimates • Confidence that reflects YOUR regularity, not a generic average • Works offline — your forecast is always there, even with no signal YOUR DATA STAYS YOURS Your cycle is deeply personal, and we treat it that way. Wen is built privacy-first: no third-party advertising trackers, no selling your information. Your health data is used to help you — and that's it. BEAUTIFUL HOME-SCREEN WIDGETS See where you are without even opening the app. Wen's widgets change with your cycle — a soft red drop for your period, fresh green for your fertile window, a sparkle for ovulation, and a calm countdown the rest of the month. Small and medium sizes, in your chosen color. SHARE WITH SOMEONE YOU TRUST Cycles affect more than one person. With partner sharing, you can gently keep someone you love in the loop — so they understand, support, and show up at the right moments. MAKE IT YOURS Wen should feel like you. Choose from warm themes and a set of alternate app icons to match your style and mood. THOUGHTFUL REMINDERS, IN YOUR LANGUAGE Get gentle nudges before your period and around ovulation — delivered at the right time in your day, in your own language. Quiet, kind, never naggy. GENTLE BY DESIGN • Clean, calm interface that's easy on the eyes • Fast logging — a few taps and you're done • Sign in securely with Apple or Google • Designed for real, irregular, human cycles — not just textbook ones Wen is here to help you notice patterns, plan ahead, and feel a little more at home in your body — softly, privately, every single day. Note: Wen provides estimates to help you understand your cycle. It is not a medical device and should not be used as a method of contraception or to diagnose any condition.
