Berlin-based Clue, which makes a period tracker app designed to let women keep tabs on their monthly cycles and help predict their fertile window, has closed a $7 million Series A round, with investment from New York’s Union Square Ventures and London-based Series A fund Mosaic Ventures. The new round brings Clue’s total raised to-date to $10 million.
Clue launched its app in 2013, and says it now has more than two million active users on Android and iOS in over 180 countries. It’s currently available in 10 languages.
As well as tracking periods, Clue users can also choose to keep tabs on other hormonal changes taking place during their monthly cycle, such as low or high sex drive or PMT related symptoms such as low energy levels or insomnia. The app also lets users record when they had sex — useful data to correlate with your fertility window if you’re trying to get pregnant.
