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. Still not sure? Download the app and test out our Demo Mode. The app supports syncing with Apple Health. *E.

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 available as a method of birth control in the US, Europe, Canada, Australia and Singapore. In countries outside the US, Europe, Canada, Australia and Singapore, Natural Cycles is intended to be used for fertility monitoring. ○ 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.
