Clue period tracker

Clue is a pioneering menstrual health and fertility tracking application founded in 2012 by Danish entrepreneur Ida Tin, who is widely credited with coining the term 'femtech'. The app was officially launched in 2013 with the goal of bringing reproductive health discussions out of the shadows and into the mainstream through data-driven science. Unlike many competitors that utilize a 'pink and flowery' aesthetic, Clue is known for its gender-neutral, scientific design and rigorous approach to medical accuracy.

Technically, the product is 'manufactured' or developed in Berlin, Germany, where the company's engineering and product teams are based. As a digital health product, its production involves software development and data science rather than physical assembly. The company operates under strict European data privacy standards (GDPR), which has become a significant part of its brand identity, particularly for users concerned about the security of sensitive health data.

Ownership of the brand remains with its founding company, BioWink GmbH. While the company is venture-backed by a diverse group of international investors—including Union Square Ventures from the United States and Balderton Capital from the UK—it remains a privately held German entity. This independence allows Clue to maintain its focus on scientific research and user-centric health tracking without being absorbed into a larger consumer goods conglomerate.
