Flo is a fertility app that analyses early symptoms of PCOS by keeping track of the monthly cycle. Here is how it works. Users can keep track of their menstruation in great detail and enter any symptoms they may be experiencing into the app. Flo, in turn, displays women’s monthly reproductive cycles with the help of AI algorithms. All of the app’s functionality is personalised for every individual user. It aims to act as an early predictive and self-management tool by offering users highly detailed descriptions of their cycle. By mapping recurring symptoms, Flo registers potential health risks to unearth underlying conditions at an early stage.
