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 today—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 “Still 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 estimates—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.

Sundial is a screen time app built on one idea: a limit should feel like a sundial, not a stopwatch. You decide what your time is for, and the app quietly holds the line. LIMITS THAT ACTUALLY SHIELD Choose the apps or categories that eat your day and give each rule a daily allowance. When it runs out, iOS itself blocks the app — not a timer you can swipe away. One rule can hold any number of apps at once. THE BLOCK TELLS YOU WHY Every shield says what you finished ("30 min done for today.") and repeats the reason you set that rule — "For my health. Put the phone down." The exit stays yours as well: finish for today, take 15 more minutes, or lift that rule until midnight. Nothing is a dead end. TODAY, AT A GLANCE The home tab estimates how much of the day you have spent and turns it into a health score that drains as the hours do. The day's ink-wash landscape shifts with it, so the picture tells the story before the number does. HISTORY WORTH READING All history in one heatmap, plus a per-day breakdown of where the time went: which apps, which categories, and how they compare with your limits. THE HOME SCREEN WIDGET Today's figure and your most urgent rules, small or medium, right on the Home Screen. QUIET BY DESIGN Everything stays on your iPhone. No account, no server, no analytics, no ads. Sundial reads only aggregate usage time through Apple's Screen Time framework — never what you do inside an app. Full policy: see the Privacy Policy link below. SUNDIAL PRO A single one-time purchase unlocks every theme, every background scene, and the Home Screen widget. No subscription. REQUIREMENTS Sundial needs Screen Time permission (Settings → Screen Time → Sundial) to read your totals and set limits. iPhone.
