If you’re trying to have a baby, you shouldn’t rely too heavily on an app, especially if you’re finding it hard to conceive. Various factors such as diet, exercise, body weight, and ethnicity can play a role in a woman’s menstrual cycle and a couple’s chance of conceiving. While the Flo app allow users to input this information, changes such as an increase or decrease in body weight, or times of high stress, which may lead to irregular menstrual cycles, are not incorporated into the algorithms that predict when a woman will be most fertile. This may contribute to a delay in conception and lead to distress, particularly if a couple has already been trying to conceive for many months. On the plus side, consistency in using the Flo app may assist in getting to know your body better. The Flo app can be beneficial for documenting monthly cycles and help women identify when their cycles may be irregular.
