Yearly plan*
Sign up for a yearly subscription and get a thermometer included in the price, shipped to you free of charge. This is the most beneficial choice.

Monthly plan*
Sign up for a monthly subscription, Note that a basal thermometer is not included when registering with a monthly subscription. One can be purchased directly within the app, or on our webshop.

Free trial month
We offer a free trial period of 30 days. This is so that everyone can try out the app before making a decision of which subscription suits you best. The free trial will automatically expire after the 30 days, and you'll need to create a subscription to continue with Natural Cycles. You do not need to cancel the free trial.
