Lily is a remarkably powerful, yet beautiful and easy way to determine the fertile and infertile phases of your cycle. It is the perfect tool for you to learn more about your body, while being discreet, reliable, and absolutely private!

You want to learn more about Lily and how it works? Head over to http://whimsicallily.com for more detailed information!
Once there, make sure to take a quick look at our privacy policy as well. We are absolutely sure that you will love what you can read there!

Lily lets you evaluate your cycles either based on averages (comparable to the calendar method,) or based on your bodys own symptoms using either FAM/NFP (Fertility Awareness Method/Natural Family Planning) from the US, or NFP (AG NFP) developed by workgroup NFP from Germany. Your choice!

Lily can be a great little helper for you to achieve your family planning goals, and it works incredibly well for both: women who are trying to conceive, as well as women who are trying to avoid a pregnancy. Lily is also used by many women who simply want to learn more about their own body!

Evaluating your cycles based on averages is easy as pie, but a little less accurate. And even though the evaluation of your cycles based on your bodys own symptoms requires a little more effort, Lily will be able to evaluate your fertility much more accurately – which is especially important if you want to use Lily to help you avoid a pregnancy.

If you want to use Lilys averages-based evaluation method, you can start right out of the box. All you need is the starting day of your past period, or two.

To successfully evaluate your cycles using one of Lilys symptoms-based evaluation methods, all you need is a thermometer labeled for taking your basal body temperature with two decimals behind the dot for °C, or with one decimal for °F – and thats it! You dont need to know or learn any complicated rules, Lily will do the work for you!

Lily also includes these features:
• see the time you are most fertile during your cycle and an estimated for the begin of your next period
• predict your 12 upcoming cycles
• charting of your temperature (Fahrenheit or Celsius)
• charting of your cervical fluid and its changes throughout the cycle
• view your data in the graph and calendar and get detailed information for every day by the touch of a finger
• add details on your love life (with or without protection)
• record interferences that may have lead to higher temperatures
• record period flow and associated symptoms
• record your mood
• password-protect your data
• an extensive in-app help
• discreet name and icon to avoid awkward moments

You can unlock even more features with an in-app purchase (We do have to pay our bills somehow!):
• more tracking menus: Cervical Position, Secondary Symptoms, Custom Notes, Medication, Diary, LH/OPK Test Results, and Menopause Symptoms
• rearrange the Your Data menu, as well as the ability to hide tracking menus you dont need
• a dark theme, including the ability to let Lily switch between the dark and the light theme automatically depending on the time of day or your display brightness
• print your charts and data via AirPrint, or export and send them as PDF documents via email to your physician or anyone else you like
• smart reminders that tell you whenever Lily still waits for important data
• custom reminders for anything you want
• change Lilys pink to any hue you like

Pros and cons of Lily - Fertility Calculator app for iPhone and iPad

Lily - Fertility Calculator app good for

It takes a few days to figure this out, but once I did, I found it to be the most comprehensive app if its type! The graphics are beautiful and as far as accuracy goes, we shall have to see ;) More information included with the app (such as a demo video) would be great for first timers, but all the info can be found online! Thanks!
Love the app. Did lots of reading on the fam prior and this app holds true to it. I wish the printouts printed the monthly chart with asterisks by dates you have entered extra info on or somehow show extra inputs by the dates on the chart. Easier to catch reasons for abnormal temps that way. Also would like the type of cervical fluid to show up on the print out. But overall I recommend it!
Great app! Blows the others out of the water in terms of being able to chart all the various fertility factors one needs to chart when trying to understand your own fertility and allows you follow FAM. Only wish ovulation test results were chartable. Havent printed anything yet but love the iphone interface! So easy to use and I havent even read the instruction manual yet!
I like it so far, Ive only had it for a few days. All along Ive been charting on paper. This is way better. Its great that my husband can have it on his phone and know my fertility too. One draw back Ive noticed so far is about the cervical position. The method Ive been using all along has more fertility symptoms concerning the cervix. Not only is there level, opening and firmness, but also the position (like straight or tilted). But to make up for this Ive added an optional menu. Another downside is that there are so many cervical fluid sensation and appearance options. I wish that these were customizable. I think it would be good to keep whats there for women who are new to NFP, but for those of us who have been charting for a while it would be nice to use our usual descriptions. All that being said, this NFP app is by far the best. I was reluctant at first to purchase it, but after looking into the others I found that Lily while it had a few drawbacks (the two I mentioned all all Ive found), had way more to offer than the others.
This has been so helpful in tracking and predicting fertility. Thank you so much.
This app is easy to use and beautiful. Ive been traveling a lot lately and its great that all I need to bring is my iPhone instead of a wad of papers for charting. It follows fan very closely and I appreciate that.

Some bad moments

The app looks good but there is a huge bug : I cant save my temperature for the current day !!! Which was pretty much the whole point !
I found this app was hard to use and a waste of money. There are much better apps that can do what this app is trying to do for less money.
I used this app for months to see if Id get used to it and like it. Its not user friendly, to expensive, and told me I was pregnant when I wasnt. Its a waste of money. Do the FAM method on paper. Its easier.
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
The app used to be intuitive, straightforward and elegant before the update. Now it is needlessly complicated, and harder to use. In this case, less is more.
This app is great. It has all the features I was recording on paper, but more organized. Daily charting is fast and easy.
