Clue Information

Clue is the #1 doctor-recommended period & cycle tracking app available on iOS, Android, and Apple Watch. Across the globe, more than 10 million active users rely on Clue to help understand their bodies better and keep their data safe and private. Clue’s mission is for women and people with cycles to make good choices for themselves, and live full lives not in spite of their biology, but in tune with it. Clue was founded in 2012 by a Danish female entrepreneur, Ida Tin, who is convinced that technology will profoundly change the future of family planning. The app calculates and predicts users’ periods and PMS based on users’ data and calculates fertility windows based on global averages, which can be made more accurate by users’ entering ovulation test data. Their newest offering, Clue Plus, aims to make Clue accessible to as many people as possible around the world at only one euro (or the local currency equivalent) per month. Clue Plus offers enhanced Analysis and personalized predictions for cycle-related symptoms with Forecast. Clue launched helloclue.com in February 2018 to help close the knowledge gap about the menstrual cycle—with information that’s accessible, serious, scientific, and empathetic. Numerous major media have greatly praised Clue, including TechCrunch (“Clue is the most underrated app ever”), BuzzFeed, Wired (“Hottest Startups 2015”), Cosmopolitan (“We love Clue”) and The Huffington Post (“Awesome”). The Berlin-based startup has the backing of prestigious investors such Union Square Ventures; Mosaic Ventures; Groupe Arnault, the controlling shareholder of LVMH Moët Hennessy - Louis Vuitton; Brigitte Mohn of Bertelsmann; and entrepreneurs from Spotify, SoundCloud and Dropbox.
