12 million people in over 190 countries rely on our app.
Our content is science-based and written by reproductive healthcare clinicians and science writers to provide people with essential, evidence-based education about health, periods, and sex via helloclue.com.
We strive to create an app that’s accessible to our diverse community of users, taking into account gender, age, race, ethnicity, accessibility, education, country of origin, socioeconomic status, and all the other aspects of an individual's background. Clue is currently available in 15 languages and growing.
One of Clue’s co-founders, Ida Tin, coined the term femtech in 2016 to define the group of technologies that are designed to support and advance women’s healthcare.
The technologies within this category include fertility solutions, period and fertility tracking apps, reproductive system health care, women’s sexual wellness products, pregnancy and nursing care, period care goods, at-home fertility monitoring devices and general healthcare.
Co-founder & Chairwoman
Ida knew immediately that in order for these products to be taken seriously, the market needed to be defined, so she suggested that Clue should begin to call itself a femtech company.
By defining the group of products that are associated with female health, we are creating an entirely new category of technology. Grouping these technologies paves the way for femtech conferences and VC’s to invest in femtech and create even more products within this segment that are important and needed in the world.
We provide trustworthy information, data-driven tools, and emotional support for everyone with a menstrual cycle — as an empathetic, scientific companion from first period to last period.
Everyone with a cycle is empowered to make informed choices for themselves around menstrual, sexual, and reproductive health and well-being.
We earn people’s trust by honoring their privacy, being transparent about how we use their data, and providing them with honest and accurate health information.
Care is at the core of everything we do, both in how we support and communicate with people, and in the products and technology we create for them. We genuinely wish to help them improve their lives and live more fully.
Rooted in science, Clue’s brand and products were born out of research and data. We continually strive to find the most accurate, forward-thinking information on menstrual and reproductive health, only sharing what we confidently believe in and can provide evidence for.
Clue founded in Berlin by Ida Tin, Hans Raffauf, Moritz von Buttlar and Mike LaVigne

„Klares, übersichtliches Design und einfache Handhabung, verständlich aufgebaut inklusive Hintergrundinformationen zu relevanten Themen.“
„Ich finde das Design und die Funktionen klasse! Man sollte natürlich nicht davon ausgehen, dass Algorithmen 100% den Zyklus voraussagen können, aber sie kommt schon nah dran 🤗“
„Iche benutzte Clue schon seit mindestens 3 Jahren. Mir gefällt die App sehr, vor allem, weil sie meine Zyklen - die PCOS-beding sehr lang sein können - so lang Tracks, wie sie wirklich sind. Außerdem zeigt sie mir tatsälich sogar eine Hinweis an, dass die Zyklen länger sind als sie sein sollten und nennet auch PCOS als möglichen Grund. Vielen Dank!“
