Clue Conceive is designed for people who would like to get pregnant. All you have to do is track your period dates in the app to get predictions for the fertile days in your cycle.
While the algorithm behind Clue Conceive works best for people with cycle lengths between 20-40 days and cycles that do not vary by more than 9 days, anyone can use Clue Conceive regardless of their cycle length or variability.
Clue Conceive should not be used by people who are trying to prevent pregnancy. It is not effective to be used as birth control and may put you at higher risk of unintended pregnancy.
