We stand for...

Enabling you to take control of your health

We support women and everyone who menstruates throughout their entire reproductive lives, with personalised cycle predictions, virtual health assistants, insights on general health, fertility and pregnancy.

Providing expert health information to all

Expert, evidence-based health information should be unconditional and available to everyone. We work with a large team of medical doctors and female health organisations to provide health content you can trust.

Empowering open discussion

Many reproductive health topics are still taboo, and some questions may go unanswered. Through the power of community, we enable open discussions, end stigmas, and help you to get support from like-minded others.

Keeping personal information private & secure

Privacy in the digital age is of utmost importance. Flo provides a secure platform for millions of women globally. Read more about our approach to Privacy and Security.
