KEY FEATURES:
1.Easy to understand user interface
2.Accurately predict your future periods and fertility windows
3.Keep track of your last “fun” encounter
4.Predict your due date if a baby was conceived
5.Custom color choices for high and low fertility days
6.Optional passcode to protect your privacy

The interface is simple to understand and custom color-coded. High fertility days can be shown as green and low fertility days can be shown as red, or vice versa, depending on what is most intuitive to you. This feature is very unique, as other apps have non-custom colors that can be confusing.

Upon inputting the beginning and end of your menstrual cycle, the app does all the complicated calculations for you so you know which days of the month you can let loose and have unprotected “fun” and which days to avoid. The app also incorporates the latest gender prediction theories to let you know which days may result in the conception of a boy or girl.

CAUTION:
Menstrual periods and ovulation cycles vary from woman to woman and month to month. This tool should be used as an estimate only and not as a replacement for professional medical advice.

Great app very easy to use and so reliable! It's straight forward and helps you keep track your cycle. After you enter a couple of months it's more accurate. Love this app.


It worked!

I was using this app to track my ovulation period since I am irregular. After a couple of months it was able to accurately predict that and I became pregnant :)

It's very helpful and reliable. It's knowledgable to keep us women on schedule and also help with conception. I really enjoyed knowing when I'm due for my menstrual and when ovulation starts or stops.


Would be great if...

... I could adjust ovulation day, change period start/stop dates when they are wrong, and could rely on the app not to lose my data. I've lost all my data twice now and have learned the hard way to also keep track on paper- so why use the app? I've contacted the app designers twice about this problem and haven't gotten a reply.

Not the best design

There are plenty of free fertility tracking apps to choose from and this one cannot compete with others. Deleting app.
