This test will measure the level of human chorionic gonadotrophin (hCG) in your urine. This is the hormone that is produced when you are pregnant.

Like other pregnancy tests the product can pick up a pregnancy early, but reliability improves the closer you get to the missed period. The app will ask you to begin testing yourself in the 2 days prior to your expected period and the test is 99% reliable when conducted on the day of the missed period.
