Ida Tin was born in Copenhagen, Denmark. She is the founder of Clue, a health company for women in Berlin, Germany. Tin started researching choices for birth control when she was in her 20s. She had problems caused by taking birth control pills. She learned that birth control has not changed much since the 1960s. So she decided to work on making it easier for women to plan when they have children. Another name for the use of birth control is family planning. She made an easy-to-use app called Clue to give women information on their monthly cycles. Clue is a menstruation and health-tracking app. It informs users when they are most or least likely to become pregnant. The app is available in 10 languages for Android, iOS and iWatch platforms. Clue already boasts more than two million users in over 180 countries.
