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.
