PERIOD CALENDAR & MENSTRUAL CYCLE TRACKER
Menstrual Cycle Tracker App “Cycle Day” is a simple and intuitive period calendar and menstrual cycle tracker that helps women monitor their cycle, predict important days, and better understand their bodies.
The menstrual cycle is a natural part of life, but with busy daily routines it’s easy to lose track of its rhythm. That’s why many women look for a convenient period tracker that helps them keep important dates, notice patterns, and plan their lives around their cycle.
Cycle Day is designed to make tracking your period as simple and clear as possible. The app helps you log period days, view your cycle calendar, analyze statistics, and predict upcoming periods. With this information, you can better understand your cycle, estimate ovulation, and keep track of your fertile window.
A CONVENIENT CYCLE CALENDAR FOR DAILY USE
Cycle Day works as your personal menstrual calendar that’s always within reach.
The calendar provides a full overview of your cycle, including period days, predicted upcoming periods, estimated ovulation, and fertile days. This format makes it easy to see the structure of your cycle and better understand how your body changes throughout the month.
You can add period dates, view your calendar by month or year, and gradually build a complete cycle history. The longer you track your cycle, the easier it becomes to recognize patterns and understand your body’s unique rhythm.
WHAT YOU CAN DO WITH CYCLE DAY
Cycle Day includes the key features users expect from a modern period tracker and menstrual cycle calendar:
• menstrual cycle calendar with a clear visual layout
• ability to add and edit period dates
• prediction of upcoming periods based on previous cycles
• ovulation calendar and fertile window tracking
• calendar view by month or year
• cycle statistics for the last 6–12 months
These tools help you gradually build a complete picture of your cycle and better understand your body.
OVULATION & FERTILE DAYS CALENDAR
For many users, it’s important to know when ovulation is approaching and which days may be fertile.
That’s why Cycle Day includes an easy-to-use ovulation calendar that estimates ovulation based on previous cycles. This helps you see your fertile window and better understand your hormonal rhythm.
The ovulation calendar helps you:
• track fertile days
• see an estimated ovulation date
• plan important events
• better understand your cycle
REMINDERS & PERSONAL NOTES
To help you stay on track, the app can send reminders about your upcoming period, ovulation, or other important cycle events. This makes it easier to plan daily activities and avoid surprises.
You can also add personal notes and tags to any day in the calendar. These notes allow you to record observations, mood changes, or other symptoms that may be related to your cycle.
MENSTRUAL CYCLE STATISTICS
Cycle Day also helps you analyze your cycle statistics.
