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.

Verdict
The clearest difference is price: MutLab at Free against Feminine Calendar's $0.99. Feminine Calendar's advantage is update cadence (every 5 weeks vs every 2 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
