The Research

As with any family planning method, women who want to avoid pregnancy need to know how effective this method is. 

Dot is the only app-based family planning method that is specifically designed to prevent pregnancy. An efficacy study is necessary because it allows us to identify how women are using the method in real life – how they interpret the messages and information they receive about their fertility and how they act on that information. Knowing this information will allow us to provide women with real-world information about the app. 

We expect to recruit and follow women 1200 women in the study who have recently downloaded Dot and wish to avoid pregnancy for at least one year (13 menstrual cycles). The study will collect most of the data through the app itself, including pop-ups and brief questionnaires.

To our knowledge, the Dot efficacy study will be the first to follow women over time to assess the outcomes of a pregnancy prevention app. 

Women who enroll in the study will provide information to researchers about their menstrual cycles, sexual activity, and how they are using information received from Dot to make decisions about their fertility. 

The results of the study will tell us:

  • How effective Dot is at preventing pregnancy when it is used perfectly? 
  • How effective Dot is at preventing pregnancy when it is used with some errors? 

Women who decide to participate in the research study are free to withdraw from the study at any time, for any reason. Once a woman has withdrawn her data will no longer be collected as part of the
research study.

The Dot efficacy study is registered as an observational study at clinicaltrials.gov.
