Natural Cycles has become the world’s first app to be approved as a method of birth control.

This gives couples an alternative to using traditional contraceptives like condoms, IUDs or hormonal birth control – and a 2016 study showed that it was as effective as the pill.

However we strongly advise that you do rubber-up with a condom – because it’s the only way to protect from the spread of STIs.

Tüv Süd, one of the leading notified bodies worldwide, approved Natural Cycles as a class IIb medical device intended to be used for contraception.

The fertility tracking app could change couples’ sex lives because it is a hormone-and chemical-free way of preventing unwanted pregnancy.

Which is good news for women who use hormonal contraception such as the combined pill, which has been linked to host of shocking side effects including death and depression.

Natural Cycles was created by husband and wife team Dr Raoul Scherwitzl and Dr Elina Berglund.

Dr Elina is one of the scientists who discovered the Higgs Boson which led to the Nobel Prize in 2013.

She said: “Women around the world are interested in exploring effective non-hormonal, non-invasive forms of contraception – and now they have a new, clinically-verified and regulatory approved option to choose from.

“Our high quality clinical studies, together with the required regulatory approvals, means we can provide women everywhere with a new option for contraception.

“Natural Cycles allow women to better understand their bodies so they can make choices that are right for them.”

The nifty app works by recording a woman’s daily temperature and a smart algorithm then determines whether she is fertile on that day.

It allows women to know if and when to have protected intercourse – and this can help to prevent, or plan, a pregnancy.

Natural Cycles is used by over 150,000 women in 161 countries and is the first fertility tracking app for women to be regulated as a medical device.
