Ovulation Calendar Diary [for iOS]

The Ovulation Calendar helps you determine your fertile days of the month, so you can either achieve or avoid pregnancy. The calendar is based on the date of your last period, the average Period Length and the Luteal Phase. With this information a chart is generated for each month, including details such as the next period date, the best days to conceive a boy or a girl, your ovulation day and when you should abstain to avoid a pregnancy.
