Know what's coming, and keep it to yourself. Lunation predicts your next period, your fertile days and your pregnancy week from your own cycle, then says it plainly: "Tuesday, give or take." No ads, no ad trackers, no scare screens. Everyday tracking is free and stays free. WHY PEOPLE SWITCH TO LUNATION • Your next period is on screen after two questions, before you create an account. • No ads and no tracking prompt. Your logs are never sold or shared with advertisers. • One calm notification the day before, never more than two a day, never at night. • Widgets, Control Center and Siri log a period without opening the app. • Rated 4.6 on the App Store and available in 18 languages. ◆ PERIOD PREDICTIONS YOU CAN PLAN AROUND Each period you log sharpens the next prediction. See the date, the give-or-take, the cycle day and the phase at a glance. Free accounts see three months ahead. ◆ OVULATION AND FERTILE WINDOW The fertile window and ovulation day are worked out from your cycles. Trying to conceive? Conceive mode widens the window and marks the best days. ◆ PREGNANCY, WEEK BY WEEK Switch to pregnancy mode for your week, trimester and days to go, with size comparisons and checklists for the hospital bag and the nursery. If a pregnancy ends, one tap pauses reminders for two weeks and keeps your history. ◆ SYMPTOMS, MOOD AND PMS, ONLY WHEN YOU WANT Flow, pain, cramps, mood, energy, sleep, skin, cravings and more across 22 categories. Log what matters, skip the rest. Lunation never nags you to fill in a form. ◆ CALM, NOT CLINICAL Plain words, no "abnormal", no diagnoses. When you want a second opinion, export a doctor report of the last six months in one tap. ◆ PRIVATE BY DESIGN Sign in with Apple or Google. Your data lives in your own account for backup. Apple Health sync is optional. Delete everything, including your account, in one tap. ◆ FREE STAYS FREE Logging, the calendar, three months of predictions, reminders and widgets are free today and will stay free. We will not move them behind a paywall later. ◆ LUNATION PLUS, IF YOU WANT MORE A daily briefing written for your phase, your full cycle history, twelve months of predictions and the doctor-ready PDF report. Monthly or yearly, cancel anytime. Everyday tracking never depends on it. Lunation is a wellness app, not a medical device, and it is not a method of contraception. Predictions are estimates based on the dates you log. Privacy Policy: https://lunation.me/privacy Terms of Use: https://lunation.me/terms
