If you want to get pregnant, the dates marked teal in the Flo app are particularly important. This is your fertile window. These are the days with the highest probability of conception. Plan to be intimate during this period. The circled number indicates ovulation. On this day, the chance of conception is at its maximum.

The app predicts the fertile window on the basis of cycle data, but you can help define it more precisely — log the symptoms, basal temperature and other parameters regularly. Each parameter affects forecasts — learn more on the symptoms input screen.

  • Such an intuitive app! Hannah Malone
    I’ve tried several period tracker apps on the market and nothing is as good as Flo. It’s accurate, detailed providing you with an abundance of parameters to log, and they even provide useful articles and surveys to help you better understand the complex nature of the female body.
