About Feminine Calendar
Feminine Calendar shows, on a simple and pretty calendar, which phase of your cycle you’re in, when your next period is due and your estimated fertile window. Enter the first day of your last period and the app does the rest: • Today at a glance: see right away whether you’re on your period, in your fertile window or on your likely ovulation day, and how many days until the next one. • Full calendar: period, fertile window (4 days before and 4 days after the likely ovulation day, 9 days in total), ovulation and today, month by month. • Your way: set your cycle length (8 to 55 days) and period length (1 to 9 days). • Records: log each period with one tap and look back whenever you like. • Notes: write down how each cycle went, with symptoms, mood or anything you prefer. • Share: send an image of your calendar to anyone you choose. • Light and dark appearance that follows your iPhone or iPad. YOUR PRIVACY Your data stays on your device. The app needs no account or internet connection, has no ads and collects no information about you. IMPORTANT Calculations are estimates based on the cycle length you enter. Ovulation varies from person to person and can change with stress, illness, hormonal changes and other factors. This calendar is NOT a contraceptive method and does not prevent pregnancy, HIV/AIDS or other sexually transmitted infections. If in doubt, talk to a healthcare professional. Available in English, Portuguese and Spanish.
What’s new
Version 4.0 · Updated October 27, 2026
Version 4.0: the app was rebuilt from the ground up with a fresh new look. • A new, warmer look, with dark mode. • Redesigned calendar: period, fertile window, ovulation and today each have their own shape, so you can read it at a glance. • Records with notes: each record shows the start of its note, or invites you to write one. • Text follows your system font size, including the larger sizes. • Help text corrected: the fertile window covers 4 days before and 4 days after the likely ovulation day (9 days), just as the calendar has always calculated it.
