Clue is an all-in-one period app for following your cycle, recording your physical and mental health symptoms, and estimating your ovulation window.

What we love: Customising Clue’s data options to fit your body and your cycle – keep tabs on the basics such as bleeding, pain and emotions, or dive deeper into other categories, including skin, exercise and digestion. The longer you use the app, the more it tells you about yourself. If you’re pregnant, switch the app to Pregnancy mode and get access to related tracking categories, informational content about pregnancy and more.

Clue offers knowledge about your cycle, about science and about yourself.

Quick tip: Scroll through the Content tab to get into the nitty-gritty of the app’s most asked questions. Learn about the intersection between birth control and mental health, the relationship between periods and gender, and the science behind sex.

Meet the creator: Clue is led by co-founder and chair Ida Tin, and co-CEOs Carrie Walter and Audrey Tsang. “At Clue, our mission is to empower people with menstrual cycles on their journeys to self-discovery, agency and health,” says Tsang. Walter agrees: “Clue’s vision is a world in which there are no barriers, no myths and no taboos in reproductive health and experience.”
