About

Your cycle is personal. Your data should be too. flow feel is a private period and cycle-awareness app that helps you listen to your body while keeping optional calendar guidance close at hand. FEEL FIRST Open the app and begin with what is true todayβ€”not what a calendar says should be true. Record: * Emotional feelings * Physical body signals * Energy and recovery * Connection and inner knowing * What you need * Private notes in your own words * When your period starts and flow ends Return, Rise, Open and Deepen are optional listening lenses. Choose one only when it fits, or choose β€œStill listening.” Flow Feel does not assign you a personality or tell you how you should feel. SHOW WHEN YOU WANT GUIDANCE Switch from Feel to Show whenever you want to see the smart adaptive calendar. Show begins with a 28-day guide, then adapts using your recent recorded cycle and flow lengths. It can display: * Estimated Return, Rise, Open and Deepen timing * An estimated middle window * A next-flow date range * Cycle-day and calendar-date context These are estimatesβ€”not confirmation of ovulation, fertility or what your body is doing. Your recorded experience always comes first. PRIVATE BY DESIGN Your personal cycle and listening records stay in the app’s private local data store. * No account * No ads * No social profile * No third-party analytics * No behavioural tracking * No remote backend for your records * Core features work offline * Optional reminders are scheduled locally Apple Health is optional. With your permission, Flow Feel can import menstrual-flow history and save completed flow days you confirm. Feelings, body signals, needs and private notes are not written to Apple Health. LEARN YOUR OWN RHYTHM Over time, Flow Feel can reflect repeated patterns found in your own records. It returns your observations with uncertainty and context, helping you notice what may be familiar without turning it into a rule. Use Flow Feel to connect with your cycle, remember what your body has told you and choose when guidance is useful. Flow Feel does not diagnose medical conditions and is not contraception, fertility, pregnancy or medical advice.
