Calculadora Fértil e Ovulação - Google Play

Want to get pregnant or better understand your cycle? The Fertility and Ovulation Calculator shows your fertile days, the day of ovulation, and the date of your next period, based on the cycles you track. Simple, beautiful, and in Portuguese.

It uses the calendar method (Ogino method), the same calculation many women do on paper, but automatically adjusted to each cycle you record.

🌸 YOUR CYCLE AT A GLANCE
• Cycle ring with today's date and each phase in color
• Chance of getting pregnant on the day: high or low, and the day with the highest chance
• Upcoming dates: start of fertile period, ovulation, and next menstruation
• Notification when menstruation is late

📅 MENSTRUAL CALENDAR
• Menstruation, fertile period, and ovulation marked with bright colors
• Prediction of upcoming cycles, to plan the month
• Tap on a day to see the phase and the chance of getting pregnant

🔔 ALERTS AT THE TIME YOU CHOOSE
• Start of fertile period, ovulation day, and end of fertile period
• Menstruation approaching, 1, 2, or 3 days in advance
• Reminder to track menstruation
• Discreet mode: the notification does not show the content, only "We have a message for you!"

• Alert center with upcoming and recent notifications

📝 COMPLETE HISTORY
• Record your menstruation with flow, symptoms (cramps, headache, bloating, and others), and notes

💗 MADE FOR YOUR GOAL
Choose between wanting to get pregnant, wanting to avoid pregnancy, or just tracking your cycle. The app adapts the texts and recommended alerts for you. Those trying to conceive receive an alert when their fertile days begin.

❓ HELP ON EVERY SCREEN
Still have questions? Tap the help icon to see answers about the screen you're on. There's also the Help Center, with search, and the "My alerts aren't arriving" check, which helps resolve notification problems.

🌙 DARK MODE
Light or dark theme, or the app follows your phone.

🔒 YOUR DATA STAYS ON YOUR PHONE
No account creation required. Your records are saved on your phone and backed up to your Google account, so you won't lose anything when you switch devices.

⚠️ IMPORTANT
The calendar method is an estimate and is not a contraceptive method. To avoid pregnancy, use a method of protection and talk to a healthcare professional. The app does not replace medical advice.
