Lily - Fertility Calculator App Reviews

A touch expensive, but really nice to use.

Great app with so many useful features to track your period / fertility The ability to export data in PDF format is the best though!

Considering the cost I had much higher expectations. I thought like other fertility apps it would at least give me prediction dates of when I will ovulate or when my next period begins. Very disappointed

I spent one night reading through the entire how-to PDF. After using the app successfully to prevent pregnancy, we decided to conceive and was pregnant the very first time we tired. I knew the exact day we conceived, the day I ovulated and the days I took pregnancy tests. Even through pregnancy its usable because it tells you how far along you are and when your due. Its just a great app if you are looking for something thorough, Ive tried many ovulation predictor apps and this is far above the others.

One of the best fertility apps, but in an age of multiple devices per person its impractical not to sync across devices such as computer, iPhone, iPad. Thanks!

Disappointed that I can no longer edit cervical fluid quantity. Also, app refuses to recognize that I am pregnant. How often do you need to enter positive tests for it to believe you?

This is by far the best fertility tracker Ive seen, and certainly the one Id recommend to my patients. Very good UI, very classy, can track anything you need and is very discrete.

I paid for Lily Pro and it makes charting so simple! Highly recommend.

I got this app when going off the pill just to see how long my body would take to adjust. I have now been using Lily for years and the awareness and knowledge it has allowed me to have of my body is a continuing source of empowerment in my life. Thanks Lily!

Ive used this app in helping prevent pregnancy and Ive used this app in helping become pregnant. Its beautiful and easy to use.

Easy to use, beautifully designed, well worth the low purchase price. I depend on Lily every month in tracking my cycle.

I love this app. Keeps everything organized, simple to use and reliable. It would be better if the fertile and the peak bars were similar colors. Or if the peak bar could be a brighter more stand-outish color such as orange. It is easy to get the purples mixed up. The peak is now light blue, and the non fertile is dark blue.... These two bars should not be similar colors but contrasting.

I tried a couple different apps before settling on Lily and I have not been disappointed. It has all the features I need and more. Its beautiful and easy to navigate. You can tell that the designers put a lot of thought and work into it. Love it!

Really good: easy, beautiful, all necessary details included. Nothing unnecessary- thats important too. Thanks. Id combine it with alarmclock;)

Where do I go to purchase Lily so I can unlock the other features?

Its is good because it has a passcode and stuff but there is a lot of things to pay for. Plus,I got the app to prep for the first time I get it.

Just switched to this one based on an article that rated it high with few others to actually be backed up by research. Have been really happy with it so far.

Finally... A visually pleasing, simple, thorough app for tracking FAM practice. Thank you Lily!!!

It’s not the most fully featured app, but despite another company’s newer app that had more features—iOS Health integration and an Apple Watch app (and gender neutral styling)—and claimed to be “beautifully scientific,” I have come back to Lily realizing that the most important thing about a cycle tracking app is its analysis because Whoever programmed Lily obviously has a deep understanding of sympto-thermal methods such as Fertility Awareness Methods (FAM), Natural Family Planning (NFP). While I have not yet read up on the Billings Method, I can say that for the past two years, I—with only a basic understanding of cervical fluid that Toni Weschler covers in her books—have been using cervical fluid only and have been pleased with this app’s analysis. And now that I have a Yono ear thermometer, I have been using cervical fluid *and* BBT for a full cycle now and can say that Lily analyzes also the BBT data expertly. My only quibble is that when I using cervical fluid only, every day was a fertile day, which is obviously not true. That said, I don’t think I ever disagreed with how it calculated my date of ovulation. Throw in cervical fluid and BBT, and now it gives me not only my date of ovulation but also my fertile/infertile days its analysis is spot on. As for the styling, yes, Lily has stereotypically feminine colors—pink, light blue, purple. But, if you can ignore that, this app is not cheap, or cartoonish, or otherwise unrefined and looks very professionally designed. And I especially like that that the app has day/night modes whose times you can customize. It would be nice to have iOS Heath integration and an AW app (and gender neutrual aesthetics). But for anyone who has even only a modicum of a clue for their menstrual cycles, this is the app I recommend to them.

The app is beautiful and the information is very easy to add. I just wish the graph was better its hard to interpret. I wish there was a clear line for every tenth of a degree; like the more traditional charting applications. Other than that I love this app. Its reliable and accurate
