About

Endo Tracker

Read full description

Endo Tracker is a private, offline-first symptom tracker for people living with endometriosis. Do a quick daily check-in, and the app keeps your history for you. When it is time to see your doctor, Endo Tracker turns that history into a clear, shareable report you can hand over or print. Everything stays on your device. There is no account to create and nothing is uploaded, so your information is yours alone. DOCTOR-READY REPORTS The reason Endo Tracker exists. In a couple of taps, the app builds a PDF that summarizes the time you tracked, so you can spend your appointment talking instead of trying to remember. - Pick a date range and the report pulls your logs together for you. - Pain over time, cycle and bleeding, symptom breakdowns, medications, and your own notes, laid out clearly. - Trend charts that are easy to read at a glance. - Questions for your doctor, carried straight into the report. - Print or share it as a standard PDF, or keep past reports in one place. WHAT YOU CAN TRACK - Daily pain levels and where it hurts. - Period days and cycle, with a simple next-period estimate based only on the days you log. - Bleeding, mood, energy, and sleep. - Bowel and bladder symptoms, plus possible triggers. - Medications, with reminders and a note of how helpful each one was and any side effects. - Questions for your doctor, with a library of suggestions to choose from. TRENDS AND CALENDAR - Charts that show how your symptoms change over time. - A calendar view so you can look back on any day at a glance. - Patterns that surface as you log more days. PRIVATE BY DESIGN - All data is stored locally on your device. - No account, no sign-up, no tracking, and no ads. - Export and import your own data so you can move it without exposing it. - Light and dark themes, and full offline use. Whether you are tracking endometriosis, painful periods, or symptoms you want to understand better, Endo Tracker helps you keep an accurate record and walk into your appointment prepared. Endo Tracker is a personal tracking tool and is not a medical device. It does not provide diagnosis, treatment, or medical advice, and it is not a substitute for professional care. Always talk to a qualified healthcare professional.
