Would you trust a birth control app?

Mobile App Designed To Prevent Pregnancy Gets EU Approva

There are more than a dozen medically approved methods of birth control, including condoms, the pill and implants.

Now for the first time, a cell phone app has been certified as a method of birth control in the European Union.

Its creator, Elina Berglund, is a particle physicist who was part of the team that won the Nobel Prize in Physics in 2013. Not long after she helped discover the elusive subatomic particle known as the Higgs boson, she left her job and went searching for answers to a different mystery: how to create an app to prevent pregnancy.

Berglund had relied on a hormonal birth control implant for ten years, but she and her husband were thinking about having kids and wanted a natural way to avoid pregnancy. None of the existing apps met her standards, so the couple used math to create one. She says programming the app wasn't that different from particle physics.

"Instead of looking for the Higgs particle, you're looking at women's temperatures and fertility data, which is a lot of fun," she says.

Berglund and her husband launched the app, Natural Cycles, in Sweden in 2014. It relies on a woman's recorded daily temperature — taken with a highly accurate thermometer — and details about menstruation to determine fertility. On days where the risk of pregnancy is high, a red light indicates you should avoid intercourse or use protection to prevent pregnancy. A green light means the risk of pregnancy is low.

Fertility tracking isn't a new idea. Dr. Paula Castaño, an OB-GYN at Columbia University, says women have been charting their periods forever.

"We've just had to use initially paper calendars, and then calendars on our phones, and ultimately now specific apps that can help us do that."

Castaño says, in general, menstrual cycle tracking apps are popular. There are more than a thousand to choose from, and women download them for different reasons.

"It could be you just want to know when is my next period going to come, and is that going to coincide with my vacation, or can I use it to help avoid pregnancy or plan for a pregnancy," Castaño says.

The Natural Cycles app stands out because it is the world's first to get approval by a European health agency as a contraceptive. In a clinical study of 4,000 women who used the app — along with a very sensitive thermometer called a basal body thermometer — the results were much better than traditional fertility-based awareness methods. Only seven out of 100 women got pregnant compared to about 24 out of 100 using the rhythm or calendar method.

It's still significantly less effective than other forms of birth control.

"You could argue that the app may be comparable to someone who may not be taking the pill very consistently or accurately," says Dr. Ellen Wilson, an OB-GYN at the University of Texas Southwestern. "But if you take the pill on a regular basis and don't miss any, I don't think you're going to have a natural family planning method that is going to compare."

Used perfectly, the pill has an effectiveness rate of 99.7 percent; however, factoring in actual use, the effectiveness rate drops to 92 percent. That's compared to 93 percent for the Natural Cycles app. The effectiveness rate of long-acting birth control, like an intrauterine device (IUD), is nearly 100 percent, and there's no need to avoid intercourse for days or even weeks of the month.

Dr. Castaño points out some women want a natural alternative.

"So it's great for them to have something that they can use that's based on some sound medical evidence," she says. "Very few apps even have that."

Natural Cycles has more than 300,000 users. It costs about $10 dollars per month, although most users pay yearly at a lower rate that includes a basal body thermometer.

There are no ads, and Berglund says personal data isn't shared with any third parties. So far, most of the women who have signed up live in Northern Europe, but Berglund has her eyes on the U.S.

She says the goal isn't to replace other forms of birth control, but to provide a more accurate, mathematical update to an ancient option.

The app is just a way to keep a record for a method of non hormonal birth control/fertility tracking that women have done for many years. If I used that form of natural family planning (such as taking temperatures of checking cervicsl mucus), I might use the app to track it. That's all the all is doing - just replacing pen and paper documentation.

Yes... I used the Fertility Awareness Method as birth control for many years, and used the OvuView app to keep record of it.

This is electronic tracking of your BBT, which I did for 2 years trying to get pregnant. It's a MAJOR pain in the ass and has to be damn near perfect to follow it.

It's probably harder to do this than it would be to remember to take a pill.

It still requires ownness and participation from the end user.

I thought this was going to be something like a Bluetooth IUD that pairs with your phone.

Exactly.

That's just recording NFP which has been around for ages. I only used it will TTC and my husband has a vasectomy. That shop has sailed but I would have appreciated the info while making birth control decisions. I used to pill prior to TTC.
