Natural Cycles is more than a period tracker. Most other fertility tracking apps assume your cycle is 28 days long, even though 87% of women have cycle lengths that don't fit into the 28 day pattern... We understand that birth control is not a one-size-fits-all. Your cycle is unique to you! Our algorithm uses personalized temperature data to confirm your ovulation, reducing the risk of you being assigned an incorrect fertile day. Unlike period trackers, the NC° app allows you to identify your fertility status daily, so you can prevent pregnancy or plan for it with greater precision.
From birth control to planning pregnancy and every cycle in between – Natural Cycles is there for you with each stage of your fertility journey. Still not sure? Download the app and test out our Demo Mode. The app supports syncing with Apple Health.

Makes my life a lot easier
I’ve been using this app for about 5 years now and I love it. It’s completely part of my daily routine. Fun and easy to use. Now even easier since I have an Oura Ring. Totally worth it. I never worry about birth control, always know exactly when I can get pregnant. And I know my body a lot better nowadays. Also, the app is very well designed and a lot of improvements over the years have been made. High quality and great customer support.
Love it!
You’re constantly learning new amazing things about your body and health, empowering you to take back the driver seat over your reproductive health!
empowering and easy
great! you get to know your own body better which is a powerful feeling. you dont have to rely on yourself in google or a doctor who doesnt have enough time for you to explain everything in detail and as we are all unique we have to know ourselves better than anyone else.
natural cycles is not only giving important information, but also communicates it naturally and open. easy and enriching!
Be careful girls
Well, I’m pregnant despite having seriously follow the instructions and taking correctly my morning temperature... Apparently the app is unable to predict irregular cycles or any little variation! Be careful girls, obviously it doesn’t work every time!
amazing
it's amazing to see how the innovation & technology impact our everyday life! It's a huge step!
Application works amazing!
7 month of successful contraception
And very happy not having to be on the pill
Best natural contraceptive
I was charting my cycles before I used this app, but it makes things so much easier! I’m glad I found it!

Es wird alles bestens erklärt und es macht Spaß die App zu verwenden.
So lange hab ich nach einer Verhütung gesucht ohne Hormone
Und bin endlich fündig geworden ich bin super happy damit.

It takes a while to get into measuring but the trick is to measure first thing when you wake up. The thermometer saves your reading once, so you can press the off button - snooze - and press it once more to check it again. I love using it now, who knew that getting to know your body could be so exciting and informative?
