What is Natural Cycles?

Natural Cycles is a fertility tracking app to help prevent, plan and monitor pregnancies. With over 150,000 users in 161 countries, Natural Cycles is the world’s first approved app that can be used for contraception and, in clinical studies, was shown to be as effective as the contraceptive pill. Natural Cycle’s mission is to educate and empower women to take control of their fertility and future, championing a vision where every pregnancy is wanted. Natural Cycles was founded by husband and wife team Dr Raoul Scherwitzl and Dr Elina Berglund who was part of the Nobel Prize-winning team that discovered the Higgs boson.

Product features

Natural Cycles works by identifying a woman’s ovulation and fertile window by tracking her period and temperature. Women are required to record the temperature under their tongue in the morning and enter it into the app which uses a unique algorithm to determine whether you are fertile on that day. The unique algorithm has collected data from hundreds of thousands of cycles which means that it can adapt to each individual woman’s body and, with a high degree of precision and accuracy, determine when she is ovulating which will help her to prevent or plan a pregnancy. Natural Cycles comes with a yearly subscription and includes the shipment of one basal thermometer.

    When we started trying for a baby, we used Natural Cycles to help track my fertility. The gift pack arrived, complete with thermometer, and being a bit of a packaging geek I was already impressed with how smartly presented the whole package was in the sleek purple and white pull-out box.

    Having downloaded the app from the iOS App Store and read the short quick start leaflet I was up and running in minutes, having created a profile on the website with my key information in it (e.g. height, weight, date and length of previous cycle etc). Once your profile is created, you start to record your temperature – taking a quick 30 second reading under your tongue every morning when you wake up – and enter it into the app, together with any additional information such as if you are on your period at that time. This process couldn’t be any simpler. The app is extremely user-friendly and opens straight up into the calendar page, you then click on the plus symbol in the top right corner, enter your data for that day and save.

    From this, the app tracks your temperature and cycle so that after about a month, it can determine how likely you are to be fertile (in particular when you are at your most fertile). Natural Cycles do advise that for the algorithm to work properly, you should not record your temperature if you’ve had considerably more or less sleep than normal, or excessive alcohol – so using the product in the run-up to Christmas there was the occasional morning I skipped a reading!!

    After a couple of months of use, we were delighted to find that I had fallen pregnant – and I am certain that we benefitted by being able to track my fertility through the Natural Cycles app. It was much more accurate and informative than trying to figure out ovulation dates myself, which would have very much been a case of ‘guesstimating’!

    The whole process itself is super simple. The gift pack and the app icon on my phone are discreetly packaged/branded with just the simple Natural Cycles logo – not glaringly obvious what they are if you don’t want other people knowing you are trying for a baby. The process is really unobtrusive in daily life – a quick reading in the morning and you can forget about it for the rest of the day whilst the app does the work for you in figuring out your fertility dates.

    You can use Natural Cycles as a contraceptive method too. Personally, I’m not sure if I could ever rely 100% on an app to do this…I’m too much of a coward to take the chance! But if you were going to use an app for contraception, I would think Natural Cycles would be worth considering.

    The gift pack costs just over £40 for six months. Or you can subscribe for monthly or yearly plans from £4-7/mth (there is also a free one month trial). Considering the cost of ovulation kits etc, I’d say this was a very reasonable price for an accurate fertility tracking pack.

    Overall, I thought Natural Cycles was brilliant and very easy to use for planning a pregnancy. I would definitely use it again.
