Fefi presents an iPhone app for tracking symptoms, understanding medical reports, and preparing a one-page PDF for a gynecology appointment.

Landing page captured for the 2026-09-27 issue.
For
People with endometriosis or adenomyosis
Worth noticing
Its flare mode puts a prewritten plan, last analgesic time, and an emergency card within reach.

Field notes

The page lays out optional symptom fields—including bleeding and medication time—rather than requiring a full form each day. It also describes tailored PDF summaries for gynecology, primary care, and an endometriosis unit. The flare-mode description includes a plan written in advance, the time of the last painkiller, and a card for urgent care; these are presented as app features, not independently verified here.
