Endii: Endometriosis Tracker

Built with the endo community. Track pain, flares, food triggers & cycles - and turn it into a doctor-ready report. Start free.

FINALLY, A TRACKER THAT GETS ENDO

You shouldn't need three apps to manage one condition.

Endii was built by a woman with endometriosis who was tired of cobbling together a period tracker, a pain diary, and a notes app before every doctor appointment. It's the all-in-one tracker designed specifically for life with endo.

MEDICAL DISCLAIMER Endii is a tracking journal, not medical advice. It does not diagnose or treat. Always seek a qualified doctor's advice in addition to using Endii and before making any medical decisions. In an emergency, contact emergency services.

TRACK WHAT ACTUALLY MATTERS • Log pain by type, location, and intensity — pelvic, back, hips, legs, not just "cramps" • 35+ endo-specific symptoms: bloating, fatigue, brain fog, GI issues, painful intimacy, and more — plus add your own • Record flare context: food, stress, sleep, exercise, cycle, and routine changes • Period tracking built around your reality — irregular cycles, spotting, and all • No period? Endii still works. A dedicated mode for hysterectomy, ablation, and hormonal suppression — no fake periods needed

FIND WHAT ACTUALLY HELPS • Snap your meals — Endii's AI reads the ingredients and watches for YOUR triggers, because everyone's endo is different • Stop a supplement or med and Endii keeps the history — then shows you how your symptoms compared on vs. off • Every treatment you've tried, with dates and effects, ready to show your specialist

SPOT YOUR PATTERNS Endii doesn't just store data — it finds the signal. Our pattern engine analyzes your logs over time and only surfaces correlations that pass a real statistical test. Which foods show up near flares? Does stress on Monday mean pain on Wednesday? When are your hardest weeks? Endii shows you — with the numbers to back it.

WALK IN WITH EVIDENCE • Doctor report: a clean PDF of your symptoms, patterns, treatments tried, labs, and photos — formatted for an 11-minute appointment • Flare report: one tap during a flare produces a one-page summary an ER doctor can scan in seconds — or show it right on your screen • Export for your AI: download your history as a Markdown file and ask ChatGPT or Claude what patterns it sees • Spreadsheet export (CSV) anytime — your data is never held hostage

SURGERY? ENDII'S WITH YOU • Pre-op checklist: questions for your surgeon, hospital bag, planning your time off • Recovery mode: "Day 6 after your lap" — what's normal this week, gentle daily checks, and red flags that mean call your care team • Keep your op notes and letters in one place

YOUR RECORDS, IN YOUR POCKET Store your MRIs, scan results, doctor letters, referrals, and op notes inside Endii — scanned with your camera or imported as PDFs. Everything lives on your device and in your own private iCloud.

YOUR BODY, YOUR DATA • Your logs are stored on your device and sync through your private iCloud — nobody else's servers • AI features only use the context you choose to analyze • No selling your health data. Period. • No research studies you didn't consent to • Export anytime in PDF, Markdown, or CSV • Face ID app lock

WHO ENDII IS FOR • Women diagnosed with endometriosis • Women suspected of having endo (tracking for diagnosis) • Anyone with adenomyosis, chronic pelvic pain, or related conditions
