Ovia Fertility has predictive engines built on millions of data points from more than 400,000 users. When you enter your data, we can make connections with other data you and thousands of other women have entered to give you the most accurate ovulation prediction possible.

Customer Reviews

Great App! So Informative!

This app has been great for tracking everything going on in my body right now. From cycle days, to fertility scores that display on the dashboard to let you know exactly where you are, to even being and to track your cp and cm! The best part is that it doesn't only document symptoms, cm, and cp, it also analyzes what you are putting in. It really helps to give feedback as far as when you are in a fertile window and things to expect during this time. This is a great tool to use in conjunction with listening to what your bod is telling you if you are ttc-ing. Download it now. You won't be sorry!!!

Easy to use and informative

This app is great for anyone who wants to learn more about their menstrual cycle, whether they're trying to conceive or actively avoiding pregnancy. You can input as little or as much information as you want, but the more you input, the more accurate of a prediction Ovia can make about your fertile window and projected period dates. It also includes articles from reputable sources that provide further information. I highly recommend it.

Love it!!!

I not only love this app to help me in conceiving, but it is also helpful for tracking my menstrual cycles and telling me when to expect my period again! I have always struggled with knowing when I had it last! I also like that it tracks your health and gives fun facts daily! Highly recommend (:
