Track your period privately, share only what helps, and let your partner know how to help today. Comfi is a period tracker made for couples. One of you tracks a cycle. The other gets a clear, kind read on the day, so nobody has to explain everything from scratch. Prefer to keep it to yourself? Use Comfi on your own as a focused period tracker. FOR THE PERSON TRACKING • Log your period, flow, symptoms, mood, energy, pain, sleep, and water in one quick check-in. • See past periods and your expected window on the calendar. Predictions show a range with a confidence level, and stay cautious with birth control, postpartum, perimenopause, and other health modes. • Notice patterns in what you log, including ones that may be worth raising with a doctor. • Copy a doctor-ready cycle report before an appointment. • Save your comfort preferences, like the foods and supplies you want, or whether you’d rather have quiet company or more space. FOR THE PARTNER SUPPORTING • See how today is going from the check-ins and cycle details your partner chose to share. • Get practical ideas for today, like lightening one task, offering quiet company, or asking whether supplies or rest would help. • Send a quick note when a full conversation feels like too much. FOR BOTH OF YOU • A private conversation for messages, photos, and voice messages. • Shared tasks with due dates, priorities, and repeats, so help turns into action. • Live location when you choose to share it, like on the way home. YOU DECIDE WHAT YOUR PARTNER SEES Choose each category your partner can receive, from daily check-ins and cycle dates to deeper health details. Hide fertility and pregnancy content if it isn’t for you. Partner messages and updates are encrypted before they leave your phone. Add App lock with Face ID, discreet notifications, and quiet hours. Core tracking and pairing work without an account. No ads, and your data is never sold. COMFI PLUS Home insights are included for everyone and use the last two days of shared check-ins and period data. Comfi Plus is an optional monthly or annual subscription. It adds Chat with Comfi, for questions about your own cycle or how to support your partner, and lets insights draw on more shared history. Comfi is not a medical device. Predictions are estimates, and AI responses are for information only. They are not medical advice, diagnosis, contraception, or emergency monitoring.
