Subscription options include monthly and annual plans. ○ Our subscription fee helps to protect you and your data. Many free apps work by selling their users’ data to third parties for advertising. Your privacy is a priority. Natural Cycles is designed to keep your data safe. 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. *E. Berglund Scherwitzl et al. “Perfect-use and typical-use Pearl Index of a contraceptive mobile app”, Contraception, Volume 96, Issue 6, 420 - 425. PRECAUTIONS: ○ Natural Cycles does not protect against sexually transmitted infections (STIs). Use a condom to protect against STIs. ○ No method of birth control is 100% effective. Even when using the birth control app perfectly, there is still a chance of getting pregnant. ○ Natural Cycles is for women over the age of 18. ○ Natural Cycles is authorized for use as birth control in the US, Canada, the UK, the EU/EEA, Australia, Singapore, Brazil, and South Korea. Outside these regions, the app is intended for fertility monitoring only. ○ To use Natural Cycles, you need to understand English or one of the supported languages. ○ Before making any medical decisions, remember to consult with a doctor. Natural Cycles connects with Apple Health to read and write your health data, including medications, body temperature and cycle information.

    Lies

    I just wrote an entire review about how garbage this company is and how misleading everything is but Apple decided to delete the whole thing so I’ll try to make it shorter this time. They suck. At first their wearable band was free with the subscription then now that I’ve already paid for the subscription it’s $100and apparently the Garmin that I purchased for this purpose is not compatible with their app, which is ridiculous because all they said was it needed to be a Garmin device only to find out that there is a fairly small list of Garmin devices that are actually compatible, which would’ve been very helpful to have on the front page after you click that you would like to go with Garmin as opposed to being on a small find print after you have already purchased your subscription and are trying to sync your watch and it’s not working for some reason. I’m so done.

    Glitchy app

    I have been using Natural Cycles as birth control for almost 2 years and while I have had a positive experience, my only complaint is how glitchy the app is sometimes. I have to open my Oura ring app to load my data for the day over and over and for some reason the Natural Cycles app struggles to communicate with my oura app. It’s very frustrating. Today I have tried to get the Oura app to load the data into Natural Cycles 5 times and it still has not worked.

    This app has been so helpful!! :)

    I have loved using this app for over a year now! It is so great for natural family planning!☺️ It has truly helped me get to learn more about my cycle and how my body works!

    Bring back cycle day on calendar

    Please update to be able to clearly see cycle day when clicking on future dates on the calendar like we used to see. The 2 stars is because recent updates to the app have made it LESS user friendly. More buttons to do the same thing we used to do with fewer buttons. Also the yearly subscription price is astronomical- I have been using this app for almost 5 years and it’s just getting out of control with the pricing. I’ve not seen added value. Being able to tap to focus during the ovulation test reader would be a long awaited and much needed improvement.

    Skeptical at first

    I’ve been watching this app for several years now and haven’t used it yet. After life changes I decided it was time. It not only predicted exactly when I would ovulate (I can feel my ovulation) but it also predicted the exact day my period would come. It had a different day than apple health had predicted and I’ve been using Apple tracking for many years. Natural cycles said Thursday, Apple said Friday, I said Saturday, it came on Thursday just as natural cycles predicted. Great app.

    Awful waste of money

    I’ve been logging religiously for 7 months and it still can’t even predict my period. The apple health app predicts it every time. This app is off by an entire week some times. Still have no idea when I’m ovulating.

    Please add custom trackers

    Please add custom trackers that will stay as stickers we can select daily

  • ★★★★★Jennayyy5762

    Love it!!!!

    This process of tracking my fertility via an app was scary to me at first because it is a lot of information to trust someone with, but not only has this been super effective, but I’ve learned so much about myself and my body along the way! I am very thankful for NC!

    Scammy

    I bought a subscription hoping to use it after getting off my current birth control. What the app didn’t tell before it prompted me to buy a subscription (I couldn’t go any further into the app without one) is that 1. I cannot use it while still having an IUD (I was trying to get ahead of tracking the cycle so I knew where I was at when it was removed). And 2. My Apple Watch apparently isn’t compatible with the temp reading. The app informed me of neither of these without first making me pay the $20 something to begin a subscription. When I canceled and tried to get it back, the automated chatbot kept spinning me in circles telling me the same thing - essentially “sorry you paid already and nothing we can do about it🤷🏼‍♀️”. Incredibly scammy. Terrible customer support.
