Using a period tracking app? You may be receiving inaccurate information about your body.

The majority of those apps assume everyone has the same cycle length & fertile window. While research shows that only 13% of women have a 28-day cycle.

Natural Cycles determines your fertility status based on your unique body temperature and cycle. It even works with irregular cycles.

All you need to do is add your temperature, and let the app do the work.
1. Measure your temperature and add it to the app
2. Wait for the algorithm to calculate your fertility
3. Check your fertility to prevent or plan pregnancy naturally

Learn the unique pattern of your cycle & fertility with tailored insights to help with your birth control, period tracking, natural family planning needs, and everything in-between.

The app itself is fine, but don't expect anything at all in the way of customer service. My subscription cancelled itself, and so far I've spent 3 days trying to reach Natural Cycles trying to get their help. The customer service chat is useless, and when it forwarded my problem to an email assistant, guess what? Still absolutely zero help! And it did the same thing last year, too. So go ahead if you're interested in spending money on an app that only sometimes works.

I've been using the App for a month now. I love the look of the app. It's look and design makes it a very "easy to use" app. But, I absolutely hate that the thermometer doesn't link with the app itself. It's so difficult to read in the dark without a light up screen, and it takes forever to measure temperature. It does store the latest reading but it disappears fast when attempting to retrieve it. Overall, I'll continue to use NC because the information and the tracking is spot on.

Love the app! It gives you lots of great information. It's setup well and even gives you reminders to set your thermometer out for testing in the morning. The thermometer on the other hand is the absolute worst! It takes a long time to check your temp. There is no back light to read the numbers. It says it saves the last reading but when you turn it back on to record your numbers it only stays on screen for a few seconds. I've missed multiple reading because the temp timed out.
