Euki's Story

A 2017 Ibis Reproductive Health study revealed the urgent need for a more inclusive, secure health tracking option that centered communities too often underrepresented and misunderstood by existing sexual and reproductive health technology solutions.

Enter Euki: a privacy-centered smartphone app co-created by Ibis, Women Help Women, and real-world users.

Euki is special.

It’s so much more than a period tracker.

  • Resources from trusted health experts about abortion, contraception, menstruation, STIs, and more.

  • Vetted avenues for support, including telehealth clinics and organizations providing free, confidential legal help.

It’s made with all of us in mind.

  • Inclusive resources to inspire confidence about your body and sexual health journey.

It’s serious about privacy. Period.

  • No third-party tracking! Your personal business stays your personal business.

Learn how Euki’s special security features are designed to protect your personal information.

We're serious about privacy, and these folks are too.

Your health information is your business and nobody else’s. But that doesn’t mean you can’t make empowering others your business too. There are several ways to get involved.

The Euki User Advisory Team is a diverse cohort responsible for co-creating Euki’s content, features, and design with the Euki product and design team. The team meets virtually and commits up to 5-10 hours a month to the project for six months. Team members receive a stipend for their valued participation.
