Women’s health app Flo has announced the donation of $100,000 to support Red Cross’ humanitarian mission in war-ravaged Ukraine.

In a statement on Tuesday, the reproductive health company noted nearly one million people actively using Flo in Ukraine. Flo said it aims to ensure its Ukrainian community would have access to health information and support. 

“We have made Flo Premium free for everyone in Ukraine, now and for the next 3 years,” Flo said. “We have begun the task of translating our huge library of content and health products into Ukrainian.”

The health app supports women with expert advice and resources at each stage of their reproductive cycle and provides information on sexual health. 

The company added that it had donated $100,000 to the Ukrainian Red Cross to support people who had been affected by the ongoing military attacks on Ukraine by Russia’s Vladimir Putin.

On Tuesday, the United Nations pegged the number of refugees fleeing the war at 2 million. UNICEF spokesman James Elder noted that half of that number were children, calling the humanitarian crisis “a dark historical first” in a tweet.

The United Nations expects the number of fleeing citizens to rise as high as four million people, but the European Union’s commission for Crisis Management said that Ukraine’s invasion risks displacing over seven million people, with around 18 million Ukrainians “affected in humanitarian terms.” 

The decree by Ukraine’s government prohibiting men between 18 and 60 from leaving the country means that most of those fleeing are women and children, though the UN doesn’t have exact numbers on gender.
