Go ahead and sign up for our annual subscription for 79.99USD and we will ship a thermometer right to your doorstep free of charge. With this plan you will be charged in full, once per year. Sign up to our Monthly subscription and pay 9.99USD on a monthly basis. You can also try out our Free trial version for one month. Both of these options do not include the Natural Cycles thermometer. Precautions: ○ You must be over 18 years old to use Natural Cycles ○ Natural Cycles does not protect against sexually transmitted infections (STIs) in any way. ○ Natural Cycles informs you whether and when you can become pregnant. Abstention or protection (e.g. condoms) are required on red days to prevent pregnancies. ○ As a birth control, Natural Cycles may be less suitable if you experience irregular menstrual cycles as predicting your fertile days becomes more difficult and you will get an increased number of red days. For birth control, it is ideally used by women with fairly regular and ovulatory menstrual cycles. Want to learn more about Natural Cycles?

  • Wow..this is no joke

    By Happyyelper
    Discovered this app and did some research before purchasing. This alternative to birth control is genius- point blank. Straightforward approach, the creators have done a great job of explaining how to take your temp first thing, love their IG page! I think my fave feature is the “notes” section, where I can track how I’m feeling that day and compare each month. My only complaint is that I wish there was a (better) way to know what phase of your cycle you’re in- the same way it lets you know whether or not you’re fertile for that day, wish it’d also inform you of the follicular/luteal/ovulation for that day as well...there’s the statistics page but that’s not easy to read/understand. Overall, if you get this app it takes some time and patience at first but it’s so worth it and freeing!

    There are plenty free apps that do the exact thing. They are a complete rip off. I will be filing with the better business bureau and then the Swedish equivalent konsumentverket if the refund after cancellation is not refunded. Their auto renew is theft! And the app isn’t that great. The thermometer is not bluetoothed to the app. Don’t waste your money! If I could give them less than one star I would for their horrible customer service. They state a refund is not possible. So nuts. Stay away!!!
  • Customer service is terrible

    By Hannah1596
    My app doesn't work. I paid the subscription renewal fee for a year, and I haven't been able to use it for over a week. I spoke to customer service about this issue, and after several days they let me know it was a glitch in the most recent update, multiple people were having this problem, and the devs would be fixing it. It has been several more days now, no word about an update or fix to this. They just told me to use protection since I can’t access my birth control app. If you market this as birth control, you can’t just say “sorry its not working” for over a week. The only issue is they can’t find my payment in their system, even after I sent them an app store receipt. Why not manually unlock my account for a few weeks while they fix an issue they caused? No, instead they just told me sorry, no birth control for you until we get around to fixing this. Unbelievable! Before this experience I really enjoyed Natural Cycles but paying for this and it not working for weeks is not acceptable.
  • I am so happy that I don’t have to rely on a pill!!!!!

    By Braeflynn
    I have been on birth control ever since I was 16..I have depended on this pill because I thought this was the only option to prevent pregnancy I have found this app and I am so glad I did I’m so happy I have an app to track my cycle naturally, the way it was always supposed to be for us girls.
  • If you hate birth control this is your solution

    Love love love NC 💕💕
  • Love this method!

    By Lizzieflegs
    I was on hormonal birth control for over 5 years and I hated it! I was afraid to try a natural route on my own and this app provided the perfect helper! So worth the money and I love it! Great alternative to the cons of other birth controls!
  • User-friendly great app

    By Lunitapporto
    It has helped me to understand my cycles better! It is easy to use and very intuitive I haven’t got pregnant yet but I am sure this app would help me to do it!!
  • Why didn’t I try this sooner?

    By JeCh16
    I’m 26 and have been using natural cycles as birth control for about 4 months. I never had a great experience with hormonal birth control and wanted to stop taking it... in comes Natural Cycles to save the day! It’s super easy. I do wish it included a place to log cycle symptoms like days I get zits and days I have mad cravings( I have another app to track those - they’re like clockwork each month) In summary, I love the control I feel I have over my body now that I’m using natural cycles. No more subjecting my body to hormones I know little about.
  • Better than birth control <3 Thank YOU!

    By Queen Mahhh
    I love this app. I'm Married and planning Pregnancy in the next 3 years, Natural Cycles gives me control over my body and hormonal cycle. It's great for people who can trust their partner and don't need to worry about STDs. Otherwise people should stick to Condoms ;)
  • Super easy to use and so informative

    By Ame132
    I’m only on my first month using the app but I love it so far. Easy and informative. And green days are really great ;-)
