Natural Cycles

Natural Cycles makes fertility tracking easy & accurate. The Natural Cycles algorithm finds the correct day of ovulation based on basal body temperature  with a high level of accuracy. A woman is fertile up to 6 days per cycle. The fertile window ends with the day of ovulation & begins up to 5 days before, depending on sperm survival. Natural Cycles carefully studies your body temperature to find your ovulation day & fertility.

Natural Cycles has something for everyone. It can tell you: ‌

• when you are fertile ‌

• when you are ovulating

‌• when your next period is due

• when you are pregnant

• about the progress of your pregnancy.
