Iris vs Post Pill

Every feature free. No subscription. No data sharing. Ever. Many period apps charge $10 to $15 a month, and some have been caught sharing reproductive health data with advertisers. Iris keeps your cycle data on your iPhone: no Iris servers, no account, no analytics. Your health data is never shared or sold. PERIOD & CYCLE TRACKING Log your period and Iris predicts your next one, your fertile window, ovulation day and PMS phase, mapped out weeks in advance. Color-coded calendar, day log and smart reminders included. HOME & LOCK SCREEN WIDGETS See your cycle day, phase and days until your next period at a glance, right on your Home Screen or Lock Screen. IRREGULAR CYCLE TRACKING Iris detects cycle variability from your data and switches to honest prediction ranges instead of single dates. No fertile window guessing for irregular cycles. Built for PCOS, perimenopause and anyone whose body doesn't fit the textbook. PERSONAL INSIGHTS & PATTERN DETECTION Iris turns your daily logs into useful patterns. See which symptoms, moods, discharge types, activity and vitals appear most often in each cycle phase, then tap into any pattern for phase distribution, cycle-day timing, recent history and prediction notes. After enough history, Iris can help you spot recurring signals like fatigue, cramps, mood shifts or discharge changes before they appear, with insights calculated privately on your device. LH STRIP LOGGING Log your daily ovulation test result: Negative, Positive or Peak. Iris immediately shifts your ovulation estimate to reflect your actual LH surge. Over time, Iris learns your personal luteal phase length and uses it to sharpen every future prediction, replacing the generic 14-day default with your actual biology. BBT TRACKING Log your basal body temperature each morning and Iris calculates your personal coverline. When three consecutive readings rise above it, Iris marks a confirmed thermal shift: retrospective confirmation that ovulation occurred. Pair BBT with LH strips for the symptothermal method, completely free. APPLE HEALTH SYNC Two-way sync with Apple Health. Iris reads your period history, BBT from connected thermometers, sleep and weight. Period days, BBT, LH results and cervical mucus are written back to your Health dashboard. What you log in Iris always wins; Apple Health only fills days you haven't logged. CONTRACEPTIVE & POSTPARTUM MODE On the pill, a hormonal IUD or a copper IUD? Contraceptive Mode pauses ovulation predictions, labels bleeds as withdrawal bleeds and adds a daily pill reminder. Just had a baby? Postpartum Mode pauses predictions while you recover, then resumes when you're ready. SYMPTOM & MOOD TRACKING Log mood, 14 symptoms (cramps, bloating, fatigue, acne, brain fog, hair shedding and more), discharge type with fertility context, sleep, weight and notes for any day. HORMONE EDUCATION Visualize estrogen, progesterone, FSH and LH across your full cycle, mapped to your own cycle length so the chart reflects your actual rhythm. PARTNER SHARING Invite a partner to follow your cycle: view-only, end-to-end encrypted and completely free. PRIVATE BY DESIGN Your data stays on your iPhone. No Iris servers. Optional iCloud backup goes to your own iCloud account, and we never see it. No analytics or tracking SDKs. The free version shows ads, which never receive your health data; a one-time purchase removes them. 100% FREE, NO EXCEPTIONS No premium tier. No subscriptions. No paywalls. Every single feature, from LH logging and BBT charting to irregular cycle detection, Apple Health sync, widgets, contraceptive mode and postpartum mode, is free for everyone, forever. Download Iris. Your cycle is yours.

Remember how you have been feeling after stopping hormonal birth control. Track a few things that matter to you, compare your recorded weeks, and bring a clear record to a conversation. Post Pill organizes your observations around the date you stopped the pill or another hormonal method. No account. Your record stays on your iPhone unless you choose to export it. A FEW TAPS TO START Choose your method and stop or removal date, then pick one to three things to record: mood, sleep quality, skin, energy, headache, libido, or cramps. Tap the values that fit today and see your first dated check-in immediately. Notes are optional. You can start with a known future date, too. SEE WHAT CHANGED IN YOUR RECORD Your next check-in compares with your previous entry. After check-ins on three days within a seven-day window, open your first recap for free. See how often you recorded each value, how much of the week you recorded, and the entries behind the recap. COMPARE YOUR OWN WEEKS As you record more weeks, see which values appeared more or less often in your entries, with both weeks’ counts side by side. After three weekly recaps, see a growing transition summary and prepare a selected report. These are descriptions of your observations, with visible gaps and source counts. The app does not predict what will happen next or explain what caused a change. KEEP THE DETAILS THAT MATTER Add bleeding or spotting, medication or supplement changes, pregnancy tests, illness, travel, stress, or other context beside the relevant day. Correct dates and entries whenever you need to. Three or four check-ins a week is a useful rhythm; there are no daily streaks or missing-day penalties. REVIEW BEFORE YOU SHARE Choose dates, signals, notes, and context for a CSV or PDF. Read the PDF before sharing it. Export, correction, archive, and deletion remain available. There is no account, advertising, analytics SDK, or community. Records do not sync between devices; export anything you want to keep elsewhere. START FREE. CHOOSE MORE WHEN IT HELPS. Check-ins, context, the first recap, comparisons with your previous check-in, and basic CSV/PDF exports stay free. A 14-day in-app preview starts after your first saved check-in. It requires no payment and does not automatically subscribe you. During the preview, new insights become available as you record enough entries. The full transition summary requires three weekly recaps and generally arrives after the preview. An optional monthly auto-renewing subscription continues new weekly comparisons, the growing summary, and new synthesized reports. The price is shown before purchase. Previously available results and your records remain accessible if you stop subscribing. Restore Purchases and Manage Subscription are available in the app. For adults who have already decided to stop hormonal birth control. This is a personal record, not contraception, fertility prediction, diagnosis, symptom assessment, medical advice, or guidance about starting, stopping, or switching a method.
