Natural cycles app – everything you need to know what is hormonal imbalance in females

There are many fertility- awareness- based birth control apps but Natural Cycles is the only one that’s certified by an EU Notified Body to be used as a contraceptive in Europe. So what is it and how does it work, exactly? To learn more about the app and to see if it’s the right fit for you, read on for our Natural Cycles review below. What is Natural Cycles?

Brain child of Elina Berglund and Raoul Scherwizl, Natural Cycles is the first contraception that uses an algorithm, not hormones, to prevent pregnancy. It’s backed by clinical studies and is also certified as a class IIb medical device. As noted on their website for healthcare professionals, this puts the app in the same category as the condom.

Business Insider goes on to explain that the ova (eggs) only live for about a day. Thus, if a woman were to have heterosexual sex after ovulation, she won’t get pregnant.


However, know that sperm can stay alive in the uterus for around a week. So, if she were to have unprotected sex right before ovulation, there’s a chance that she can get pregnant.

It does this by calculating your basal body temperature to understand and get to know your cycle. As noted on Natural Cycles’ website, this temperature reading is an indirect measure of your hormonal levels. Thus, the app will use this reading to determine whether or not you can get pregnant that day.

If your cycle is irregular, the app accounts for that too. Per Natural Cycle’s website, the app will still be effective; however, you may experience more red days. This is why it may not be the most suitable contraception for women with irregular cycles.

Note that not all birth control methods are 100% effective. The pill has a failure rate of 9% with typical use, and the shot has a failure rate of 6% if it isn’t taken correctly. There’s even a 1% chance of getting pregnant on the IUD, one of the most effective forms of reversible birth control!

Based on the data, the app will determine if the day is red or green. Red days will mean that you should use back up contraception like condoms. Green days will mean that you’re not at risk of getting pregnant, even without using back up contraception.

The company recommends the app to those women who are between 20 and 40 years of age who are in stable relationships. They also recommend it to women (and their partners) who are comfortable with using condoms or other backup protection red days.

Furthermore, the Natural Cycles app is most effective when used correctly. So, if you’re forgetful with the pill or patch, it’s better to opt for the IUD or implant as opposed to a method that relies on you (like the pill or Natural Cycles).
