Berlin-based Clue announced that it has raised a $20 million round to extend the global reach of its fertility tracking app.

The round was led by Nokia Growth Partners and was officially confirmed today on stage at Slush, the tech conference happening this week in Helsinki, Finland. Other investors in the round include Union Square Ventures and Mosaic Ventures.

Clue says it has now raised a total of $30 million since it launched in 2013 and that more than 5 million women use the app, which allows them to track their menstrual cycles to know when they may be ovulating. Clue will use the money to continue hiring at its Berlin offices and for marketing the app in new markets.

“I feel as strongly as ever that Clue’s mission is to keep female health and its advancement at the top of the global agenda,” said Clue’s Danish-born CEO and cofounder, Ida Tin, “and I am thrilled to partner with a prestigious circle of investors who share our vision.”
