Know your fertile window before it arrives. Cycle planning simplified.
OvuWatch predicts your fertile window and ovulation day from your cycle data. Enter your last period start date and cycle length, and the app calculates ovulation, the fertile window, and your next expected period. A monthly calendar highlights each day type — period, fertile, ovulation, or normal — in colour. A summary card shows cycle day, days until ovulation, and days until the next period. Data stays on-device.
