pum

About

The period and symptom tracker built for endometriosis and adenomyosis. Log a flare in five seconds, see how your cycle shapes your pain, and walk into your next appointment with a report your doctor can read. Most period apps are built for the average cycle. pum is built for what your body actually does. For irregular cycles, for cycles that taper or skip or stop, for pelvic pain and painful periods, for the symptoms generic apps don't bother asking about. For the people who want patterns, not averages. A REPORT FOR YOUR DOCTOR Create a printable record of your symptoms before an appointment, laid out to the endometriosis guideline your doctor works from: NICE in the UK, RANZCOG in Australia, ESHRE in Europe. Your pain, bleeding, bowel and bladder symptoms, what you've taken and whether it helped, and pain and bleeding across your cycle in one figure. Counts and your own words, nothing more. Free, and pum keeps no copy. LOG WHAT MATTERS • pain — pelvic pain, cramps, by location, intensity, duration • bleeding, spotting, clots • GI symptoms, bowel movements, bloating, nausea, bladder symptoms • sex and medications • fatigue and mood — quick morning and evening check-ins • surgery, scans, diagnoses, doctor visits — all in one place SEE THE PATTERNS pum's analysis engine finds the relationships your symptoms hide. How sleep relates to pain. How cycle phase relates to a flare. How things look before and after a treatment change. Statistical, n-of-1, inspired by case-crossover study designs — your patterns, not population averages. It tells you how sure it is, and says so when it doesn't have enough data yet. PREDICTIONS FOR IRREGULAR CYCLES Bayesian cycle prediction calibrated to your treatment, not a 28-day default. Handles IUDs, hormonal therapy, post-pill irregularity. Tracks phantom cycles during amenorrhea so the app keeps making sense even when periods stop. Your meds, synced to your cycle phase — tranexamic acid before your period, iron during. Set it once. IF YOU SUSPECT ENDO You don't need a diagnosis to start. Clinical guidelines — including the UK's NICE guideline for endometriosis — recommend keeping a pain and symptom diary to aid discussions with your doctor. That is exactly what pum is built to be. pum doesn't diagnose -- it makes sure that what you've been living through is on the record, in a form a doctor can't wave away. 1 in 9 women have endometriosis, and the average diagnostic delay is over 7 years. pum exists for the people living inside those numbers. APPLE WATCH pum reads your sleep and wrist temperature: sleep is weighed against your pain, and temperature tells pum where you are in your cycle. No watch? Log bedtimes and a morning temperature by hand. Compatible, never required. APPLE HEALTH Import your cycle history, exercise, and sleep data to seed predictions on day one. pum doesn't need months of new logging to start being useful. YOUR DATA, YOUR AI pum has no chatbot, no AI middleman. Instead, it exports your data in a paste-ready format for the AI of your choice — Claude, ChatGPT, Gemini, whoever. Ask what changed before a flare. Compare difficult weeks to your baseline. Ask your AI to help you prepare questions for your next appointment. You drive the conversation. NO PAYWALL. NO ACCOUNT. NO ASKS. Logging your first symptom takes under a minute — no fifty-question onboarding, no paywall waiting at the end. Your health data stays on your device. iCloud sync is optional and encrypted. No ads, no data selling, no third-party sharing. pum sends only anonymous crash and usage diagnostics — never your health data, never linked to you. BUILT FOR ONE, FIRST pum was built by a solo developer with a mathematics background, for one woman with stage 4 endometriosis — on the bet that what genuinely helps one person with endo will help others. It's new to the App Store, shipping improvements weekly, and shaped directly by the people who use it.
