The Best Apps for Endometriosis Symptom Tracking (2026)

Which endometriosis app is best for what?

Many period apps track bleeding well but give pain a single slider. For endometriosis, look for an app that keeps pelvic pain, bowel and bladder symptoms and your cycle in one place, and that still works on a flare day.

Prices are standard US prices. Ratings are from each app’s US App Store listing on 28 October 2026, and features are as each listing or help page describes them. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12]

A 2025 review in the Journal of Medical Internet Research assessed the free content of 19 endometriosis apps and rated 6 as good quality: QENDO, Bearable, Luna for Health, Matilda Health, Branch Health and CHARLI Health. [13] Bearable is the only one of those six on our list. The review looked only at free features, and app stores change quickly, so treat it as one check among several.

What should an endometriosis app record?

NICE guideline NG73, the UK guidance on endometriosis, lists the symptoms that should make a clinician suspect it. [14] They make a good checklist for your tracker:

• Chronic pelvic pain
• Period-related pain that affects daily activities and quality of life
• Deep pain during or after sex
• Period-related or cyclical bowel symptoms, especially painful bowel movements
• Period-related or cyclical urinary symptoms, especially blood in the urine or pain when passing urine

NICE also lists infertility alongside any of these. [14] Beyond that list, these entries help:

• Pelvic pain by location and strength, not one number for the whole day.
• Your cycle: timing, length and which day you’re on when symptoms hit.
• Bleeding: flow, clots and bleeding between periods.
• Fatigue, which often goes unasked.
• What it stopped you doing: leaving work early, cancelling plans or spending the afternoon lying down.

That last one matters. In a 2020 study of data from 6,925 women with endometriosis who used the Phendo research app, work was the daily task most often affected (49%). [15] Our endometriosis symptom tracker page covers what to log. If you’d rather start on paper, the free printable symptom tracker needs no email, and you can also keep a free symptom diary in your browser.

Why does a symptom record matter for endometriosis?

Diagnosis is slow. In March 2026, Endometriosis UK reported that the average time to diagnosis in the UK has reached 9 years and 4 months, up from 8 years in 2020. In its survey, 39% of respondents said they saw their GP 10 or more times before endometriosis was suspected. [16]

With short appointments and years of history, a dated record that follows your cycle helps you use the time well. NICE advises telling women with suspected or confirmed endometriosis that keeping a pain and symptom diary can aid discussions. [14] A record also saves you rebuilding the story from memory for every new doctor. If you’ve had symptoms dismissed before, read how to handle medical gaslighting.

How do you choose an endometriosis app?

Our list will change. These questions work on any app:

• Fields. Does it record the NICE symptoms separately? You want to be able to show, for example, that bowel pain peaks at the same point in your cycle.
• Bad-day effort. Can you log in seconds during a flare, without being penalised for missed days? If logging is a chore on high-pain days, those are the days your record will miss.
• Export. Can you get a PDF or file your doctor can read, or does your history stay in the app?
• Privacy. Read the privacy label on the App Store listing. It shows what the developer declares, and Apple doesn’t verify it. [1] Cycle data is sensitive: in 2021 the US Federal Trade Commission finalised an order against Flo Health over allegations that, despite promising privacy, it shared users’ health data with marketing and analytics firms, including Facebook and Google, until a news report in February 2019. The order requires Flo to get users’ consent before sharing their health information. [17] [18]
• Cost and backing. What is free, what needs a subscription, and is a research or clinical group involved? Phendo, for example, comes from a Columbia University research project. [2]

No app scores perfectly on all five. Pick the one that is strong enough on the points you care about that you’ll keep using it.

How do app logs become a doctor-ready report?

Daily entries pay off when they turn into a short summary for an appointment. A good one includes:

• One dated page, not every entry you’ve ever made.
• Symptom trends across at least one full cycle, ideally two or three.
• Flares and what came before them.
• Medicines and treatment changes, with dates.
• Three to five questions you want answered.

Some apps help with this. Juno creates PDF symptom reports, ENdi exports a Health Overview as a PDF, and Flo’s doctor report covers your last six cycles and top five symptoms (a Premium feature on iPhone). Phendo lets you explore your data with your care team. [1] [3] [12] [2] Our example report shows what a finished summary looks like.

Why is Juno our pick for endometriosis tracking?

Full disclosure: Juno is our own app. Here is why we’d choose it for everyday endometriosis tracking:

• Logging that works on a flare day. Type a few words, or switch to voice when typing is too much, and Juno records the symptom, its severity and the context. [1]
• Your cycle and symptoms together. Juno compares symptoms with activities, medication and cycle information, so pain that keeps landing in the same phase is easier to see. [1]
• A report your doctor can read. Juno creates PDF symptom reports to share with your care team. [1]
• Medicines. Set reminders, mark doses as taken and review your medication history. [1]
• Your other data. Juno can bring in data from Apple Health, Oura, Garmin and other wearables and health platforms. [1] [19]

Juno is free to start: symptom tracking, health insights and doctor reports are in the free plan, with limited AI chat. Juno Pro adds unlimited AI chat and enhanced memory, at a standard US price of $19.99 a month or $99.99 a year, and it is HSA/FSA eligible. [10] [19] [20] Juno is rated 4.8 from more than 10,500 US App Store ratings. [1]

Juno doesn’t diagnose endometriosis or replace your clinician. If you want a free research app, Phendo can sit alongside it; for detailed bleeding logs and a body map, look at ENdi. [2] [3] See how Juno helps with endometriosis.

How did we choose these apps?

We included apps built for endometriosis, popular cycle trackers, and general pain and symptom trackers. Every fact about another app comes from its US App Store listing or its own help pages, checked on 28 October 2026. For Juno we used our own listing and site. This compares published features, prices and ratings. It isn’t a hands-on test of every paid plan, and no app here diagnoses or treats endometriosis.

For flares, read endometriosis flare-ups. For a wider list, see the best symptom tracker apps for chronic illness. We also compare Juno with Bearable in more detail.
