2Day Method - Fertility Awareness & Family Planning

By Cycle Technologies

This app is only available on the App Store for iOS devices.


The 2Day family planning app makes it easy for a woman to identify her fertile days and plan or prevent pregnancy naturally. It’s based on a patent pending methodology called the TwoDay Method® which was specially designed by researchers at the Institute for Reproductive Health. It’s brought to you by Cycle Technologies, the maker of Brilliantly Simple™ fertility tools that have been used by over 3 million women worldwide.

To use the 2Day Method a woman simply needs to know if she had secretions either yesterday or today. The 2Day app tracks this information and helps her see patterns in her cycle. There is no need to track temperature or to analyze secretions any further! Just a simple click to indicate whether she had secretions today or not and the app will let her know if she is fertile today.

The Two Day family planning method has been proven +96% effective in preventing pregnancy. Because it’s so easy to use, it’s actually more effective than other symptoms-based family planning methods such as the sympto-thermal and ovulation methods used by the majority of fertility apps.

ANYONE. Even women with irregular cycles can use this natural family planning tool. It is based on your own unique cycle. *

-One-click data entry makes it easy to enter information
-Instantly know if you are on a day when you can get pregnant or not
-Fertility calendar helps you readily see trends in your cycle
-Period tracker, ovulation calculator and ovulation calendar


* Women who have recently been pregnant or who have an infection may find that the 2 Day app indicates that they are potentially fertile when they are not.

This is a joke.

I entered today that I had "secretions" and he app told me pregnancy likely... yeah uh nope. First of all, we don't have secretions, we have cervical fluid or cervical mucous. Secondly, i marked that I had "secretions" because I have lots of creamy cervical fluid happening. That is not a peak type fluid! So how can this app say pregnancy likely?? I know exactly when I'm fertile based on FAM symptoms-thermal method, and I am NOWHERE near my fertile window.

everyone should know this info

i'm shocked that it took this long for people to figure this out. not sure if i'll actually use it as contraception or will just keep it as reference. either way it seems like every single girl in the world should know this information and sadly most don't.


Won't even open, keeps crashing
