What is DOT?
Dot is a fertility app developed by Cycle Technologies in collaboration with experts in the fields of reproductive health and data science. Dot has been tested in a rigorous clinical trial* and shown to be very effective when used for pregnancy prevention. It is 95% effective with typical use and 99% effective with perfect use.
Dot works by determining your chance of pregnancy for each day of your cycle. This is information that you can use to prevent pregnancy, plan pregnancy, or simply track your cycles. The only input you need to enter is your period-start date. Dot's algorithm takes multiple factors into account in addition to your unique cycle pattern to evaluate your pregnancy risk. Dot flags your days as HIGH or LOW risk when used in Preventing Pregnancy mode, and as HIGH, MEDIUM, or LOW chance when used in Planning Pregnancy and Tracking Cycle modes. This is powerful information that you can use to meet your reproductive goals.
*Dot was tested in a full-scale effectiveness trial by the Institute for Reproductive Health at Georgetown University with funding support from the United States Agency for International Development (USAID).
