Endometriosis is common, painful and slow to diagnose. Most apps just track it. UndoEndo helps you understand it.

Symptom tracking that learns

Log pain, mood, energy, sleep and triggers. UndoEndo maps every entry to your cycle, so your body's rhythm starts to show.

Pattern insights, not just data

After 14 days of logs, UndoEndo shows a pattern only when your logs and the research agree.

Daily guidance for your phase

Evidence-informed tips across five areas, matched to your cycle phase, your symptoms and your diet.

Our story

It started with one woman. It's built for millions more.

"I spent years tracking my pain in notes apps, spreadsheets, anything I could find. Nothing connected it. Nothing explained it. I built UndoEndo because no one should have to figure this out alone."

Sahel navigated endometriosis for years in a system that moved too slowly and said too little. Every feature in UndoEndo exists because people living with endometriosis deserve to feel seen, informed and in control of their own health story.

Questions

Things people ask us

Is UndoEndo a medical app?

No. UndoEndo is a wellness tracking and support app. It does not diagnose, prescribe or give clinical advice. It is designed to complement your care, not replace it. Always talk to your healthcare provider about medical decisions.

Do I need a diagnosis to use it?

Not at all. Many people are still on the path to diagnosis. UndoEndo is for anyone who wants to understand their symptoms, cycle and patterns more clearly.

When and where is UndoEndo launching?

We're launching soon in Canada, on iPhone and Android. Join the Inner Circle and you'll be the first to know the day it's live. Outside Canada? Join anyway and we'll tell you when it reaches you.

How much will it cost?

Every account starts with a 14-day free trial with full access. After that, it's $14.99 CAD a month or $149.99 CAD a year. You can cancel anytime from your App Store or Google Play account.

How is my health data protected?

Your data is encrypted in transit and at rest, and used only to provide your insights and improve UndoEndo for you. Never sold. You can delete your account and all your data at any time.

When will I see insights?

Daily tips start on day one. Patterns need at least 14 days of logs, and not everyone sees one. We only show a pattern when your logs and the research agree.
