Period technology has come a long way since the first pad — complete with straps, suspenders, buckles, and a belt — made it into stores in the late nineteenth century. Meet the period app: Women are now using their smartphones to help them do everything from graphing their flows to changing their tampons on time to predicting the days on which they’ll ovulate.
What’s the point of having so much information on the exact part of womanhood most of us would happily forsake? According to users of the apps, collecting and analyzing data on periods helps them better understand their bodies as well as tackle health problems like infertility. Many of the apps that allow period tracking, such as Kindara, Clue, and Glow, are geared toward women trying to get pregnant. In addition to the dates of their periods, users record data on cervical mucus texture and body temperature that help them determine when it’s possible to conceive.
