ClueGermany-based Clue, which has developed a women's health app, raised $7 million from Union Square Ventures and Mosaic Ventures. This brings the company's total funding to $10 million. Clue's most recent round was announced in March.

Existing investors include German private investor Brigitte Mohn; French investment firm Groupe Arnault, the controlling shareholder of LVMH (Moët Hennessy – Louis Vuitton); the German pharmaceutical company DR. KADE; and executives from Spotify, Dropbox, and SoundCloud.

The company plans to use the funds to deepen the insights that women can get from the data they enter into the app.

"We want to use the data to make our predictions even more accurate, and to make our predictive notifications more contextual," Clue CEO Ida Tin told MobiHealthNews in an email.

Clue uses an algorithm to calculate and predict a woman’s next period. Users can add other information to the app, including updates on mood, sexual activity, level of flow, and personal notes. Users can also enter their basal body temperature, set reminders and keep track of birth control pill usage. At the end of September, Clue added 23 new tracking categories to its iOS app, including type of food cravings, digestion issues and energy levels, skin health, mental state, levels of motivation, and medications.

“Reproductive rights are human rights: the right to freely decide whether to have children or not; how often and when, including easy access to contraception and the necessary knowledge about reproductive health; and the right to attain the highest standard of sexual and reproductive health,” Tin said in a statement. “Technology can and will have a huge, positive impact on all these issues and Clue is leading the way. We have so many users telling us that Clue has become such an important tool because the app not only improves their daily lives but also helps them to know themselves and their body better.”

Clue also aims to develop another new feature in the near future -- a partner offering that provides a woman’s partner with insights into her cycle.

The app, available for iOS and Android devices, has nearly 2 million active users from 180 countries. The company supports 10 languages. One of the most recent languages added, Clue Cofounder Hans Raffauf told MobiHealthNews in March, is Japanese. He explained at the time that only between one and two percent of women in Japan are on the pill.

Clue graduated from Princeton, New Jersey-based accelerator Tigerlabs Health, an accelerator which aims to draw startups that want to work with pharma companies. Tin said Clue is eventually interested in working with them.
