Natural Cycles Pricing Plans:

To use the app you will need a two-decimal basal thermometer. 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.


○ 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.

- The month view now shows 5 full predicted cycles and smarter predictions in general that change over time
