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.

User friendly

I've used this app for about 3 years now. I like it because it is user friendly but there are a few things that could be done to improve it. The bbt chart should show by your cycle, not by months because usually it is split between 2 months so you don't get a good picture of all the temps together for the one cycle. The bbt chart should also show somehow where you got a positive opk test. Those would be 2 big improvements that would make it better. I'm considering switching apps just because I need my chart to be better for me to look at and my doctor to evaluate and it's kind of hard to do that when one cycle isn't all on one screen. But other than that it's great for anyone not really needing the bbt charts.

Not Worth $5.00

I have had this app for almost a year - I was attempting to give it the benefit of the doubt. Through all the various updates that have been made over the past few months, there has not been a great change in the function of this program. Women's periods can sometimes come early, late - just because. That's nature and this app should be able to adapt to that fact - but it doesn't. Anytime my cycle varies from their "prediction" it completely erases any information that I had stored previously. Ladies just save your money and go to WebMD - because apparently these developers are never going to get it right.

Period length doesn't go beyond 34 days

Cons: I have a 40 day cycle, but I can't imput that because this POS app doesn't allow a cycle beyond 34 days. Also, I hate that I can't customize how long a period was for different cycles. Some periods can be shorter than others and the app creators need to realize this.

Pros: Simple and easy to use. I like that it's not overy cutesy or flowery. It will also predict your next periods and ovulations which is nice and will even tell you when the best time to have sex is if you want a boy or a girl which is fun if you're trying to concieve.
