Phendo App

Phendo is a free research app to track, manage, and understand endometriosis. Opportunities to reflect upon your data may help you in managing your disease.

There is a new version of the Phendo app coming at the end of March! The app will be available on the App Store and Google Play. You can sign up as a tester here.

Who is Eligible?

  • Must be 13 years or older. Those under the age of 18 will need parental permission to participate, and parents or guardians will be asked to co-sign consent.
  • Adolescents and adults who have had at least one menstrual period.
  • Adolescents and adults who have experienced symptoms of endometriosis in the past 3 months.
  • Adolescents and adults who have reached menarche but have not experienced symptoms in the last 3 months are eligible to participate as controls.

Can I use Phendo if…

  • I take contraception or hormones?
    Yes, and you can track these in the app!
  • I have had surgery to remove my endometriosis?
    Yes! You can tell researchers about your medical and surgical history in the Profile section of the app.
  • I have had a hysterectomy?
    Yes! Some women still experience symptoms of endometriosis after hysterectomy, making tracking after hysterectomy an important part of our work.
  • I am pregnant, peri-menopausal, or menopausal?
    Yes! Be sure to complete your medical history in the Profile tab.
  • I don’t have endometriosis?
    Yes! You can participate in Phendo as a control which helps our researchers distinguish which symptoms are due to endometriosis and which are typical experiences of women in general.
