Build a Period Tracker App

Menstrual health is essential, yet often underserved. A period tracker app empowers users to understand their cycles, predict ovulation, and maintain health logs. This app development project covers calendar logic, push notifications, and user-centric health design.

Users can log start/end dates of their periods, track symptoms like cramps or mood changes, and receive cycle predictions. Include reminders, calendar views, and fertility window calculations for added functionality.

The user logs their last period, and the app calculates future period dates, ovulation periods, and fertile windows based on cycle averages. A calendar view offers an overview, while logs track symptoms, moods, and sexual activity for health awareness.

• User logs first period date and selects average cycle length.
• The app predicts future periods and ovulation windows using standard fertility formulas.
• Users can track symptoms daily—like cramps, energy, acne, or mood swings.
• Calendar highlights important days in the cycle with color-coded markers.
• Notifications remind users before upcoming periods or ovulation starts.
