About Pum

Born from love, built with care, guided by research.

Why Pum Exists

Pum was created for someone I loved who I watched suffer. I wanted to better understand her body, help her take control of her reminders and data, and find patterns in the chaos of endometriosis.

Most period tracking apps are generic, predatory (50-question onboarding then paywall), and not tailored to the chaotic cycles and specific symptoms of endo, PCOS, and adenomyosis. They're designed for "normal" periods, not for bodies that don't follow the textbook.

Pum is different. It's built specifically for people whose cycles are unpredictable, whose symptoms are complex, and who deserve better than one-size-fits-all solutions.

The Science Behind Pum

Endometriosis Symptoms Are Idiosyncratic

Every person with endo experiences it differently. Pain locations vary. Triggers differ. What works for one person may not work for another. This is why generic advice and population-level studies often fail for endo management.

Pum uses n-of-1 analysis — personalized, within-person comparisons that treat you as your own control group. Your patterns, your triggers, your insights.

Symptoms Are Cycle-Correlated

Endometriosis symptoms often fluctuate with the menstrual cycle, driven by hormonal changes. Pain may worsen at certain cycle phases. Fatigue may follow predictable patterns. GI symptoms may correlate with hormone levels.

By tracking symptoms alongside your cycle, Pum helps you identify these correlations — giving you (and your healthcare providers) actionable insights about when symptoms occur and what might be influencing them.

Data Takes Time

Honest truth: meaningful pattern analysis requires months of data, not days. Pum delivers immediate utility through clinical reports, medication reminders, and cycle predictions — while building toward deeper insights as your data accumulates.

When we don't have enough data to be confident, we'll tell you. No false promises, no made-up insights. Just honest analysis when the time is right.

Design Philosophy

Like a jellyfish in the sea: transparent, elegant, beautiful, alien. Subject to the currents and cycles of a vast, incomprehensible ocean — yet riding them gracefully.

That's what living with endometriosis can feel like. And that's the experience Pum is designed to honor.
