EndoTracking vs Clue
Clue Period & Cycle Tracker
Clue is a beautifully designed period and ovulation tracker used by over 13 million people worldwide. It excels at cycle prediction and fertility tracking with a clean, science-backed interface. However, Clue was built for general menstrual health — not for the complex, multi-system experience of living with endometriosis.
Our verdict
If you have endometriosis, Clue will leave you logging symptoms in notes fields that no doctor can easily review. EndoTracking was purpose-built for endo patients: 40+ endo-specific symptoms, a pain body map, surgical history tracking, and one-tap doctor-ready PDF reports. For cycle prediction alone, Clue is excellent — but for managing endo, EndoTracking is the right tool.

Why EndoTracking — for endometriosis specifically
Three features that matter most when you have endo, not just a period.
Pain body map
Tap directly on the areas of your body where you feel pain. Build a visual record over time that shows your doctor exactly where endometriosis is affecting you — something no period tracker or general app provides.
One-tap doctor report
Generate a formatted PDF in seconds that summarises your symptom history, pain locations, cycle patterns, medications, and surgical history. Walk into every appointment prepared.
Personal flare-risk trend
A pattern-based estimate from your recent cycle, pain, sleep and stress logs — not a medical prediction.
Where Clue genuinely shines
We believe in honest comparisons. Here is what Clue does well.
Industry-leading cycle and ovulation prediction algorithm used by 13M+ people
Clean, science-backed interface with research partnerships and transparent methodology
Wide platform availability (iOS and Android) with a large, active community
Where it falls short for endo patients
No endo-specific symptom categories — bowel, bladder, and pelvic pain must be logged as free-text notes
No doctor report export, so appointment prep means manually summarising months of data
No awareness of how endometriosis affects symptoms differently across the cycle — treats all users the same
Frequently asked questions
Can I use Clue to track endometriosis symptoms?
You can use Clue's custom notes and general pain fields to log endo symptoms, but it has no endo-specific categories. You will not get structured data on pelvic pain locations, bowel symptoms, fatigue patterns, or flare correlations — all of which matter for managing endometriosis effectively.
Does Clue generate a report for my gynaecologist?
Clue does not produce a formatted PDF report for medical appointments. EndoTracking generates a one-tap doctor report that summarises your symptom history, pain locations, cycle patterns, and medications in a format gynaecologists and pelvic pain specialists can quickly review.
Is EndoTracking free like Clue?
Yes — EndoTracking is free to download on the App Store (iOS 17+), just like Clue's core features are free.
Which app is better for period tracking if I have endo?
EndoTracking includes cycle tracking alongside its endo-specific features, so you get period and ovulation logging plus everything built for endometriosis — pain mapping, symptom correlation, a personal flare-risk trend, and doctor reports — all in one place.
