Clue, an app that tracks women's menstrual cycles and predicts when they may be in pain, has raised $20 million, led by the venture capital (VC) arm of Finnish network equipment maker Nokia.
Users can input details about their menstrual cycles, then the algorithm will learn and can predict when a woman is most fertile and when they may be in pain. Its website states that it can help if you "want to get pregnant, be prepared for your next period or understand your mood swings."
The app was launched in mid-2013 and earlier this year reported about 5 million monthly active users. It hasn't disclosed the latest figures, but Clue founder Ida Tin said the user base is "growing very nicely."
