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 59.99 GBP 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 6.99 GBP 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 above the age of 18 years 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.
○ 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 contraception, it is ideally used by women with fairly regular and ovulatory menstrual cycles.
