How We Picked These Apps

We shortlisted the 7 apps compared below from what women actually use for tracking endometriosis pain, flares, and symptoms, and compared them on the criteria that matter most here: pain location and severity tracking, flare and trigger logging, medication and surgery history, and doctor-ready export. Pricing was re-verified on the App Store in October 2026, and we read each app's current privacy policy rather than relying on its marketing pages.

Full disclosure: this site is published by Holland Neurotech Inc., the maker of Veya. The list isn't ranked — each app is presented as the fit for a specific need — we include our own app only where it genuinely belongs, and we say plainly when a competitor is the better choice.

Endometriosis affects roughly 1 in 10 women of reproductive age.[2] Getting diagnosed often takes years: the WHO puts the average at 4 to 12 years,[1] and a University of York review of 22 studies found about 6.6 years.[4] Part of that delay is biology (laparoscopy was historically the route to definitive diagnosis). ACOG's March 2026 guideline now says a clinical diagnosis from symptoms and an exam is enough to begin treatment without a diagnostic laparoscopy first, though confirming endometriosis by biopsy still takes surgery.[3] Tracked data gives that conversation something concrete.

This guide compares 7 apps on what actually matters for endo: pain tracking with location and severity, flare logging with triggers, medication and surgery history, patterns over months not days, and clean reports you can hand a doctor who has 12 minutes for your appointment.

Full Transparency

This guide is published by Holland Neurotech Inc., the company behind Veya. We've compared each app based on its actual endo-relevant features, recent user reviews, and publicly available information. Every app here has real strengths, and the best one for you depends on where you are with endo, what you need to track, and which features your insurance or schedule allows.

Our goal is to help you find what works. If that's Phendo or Bearable instead of Veya, we'd rather you use the right tool than the wrong one with our name on it.

How We Compared

To compare these 7 endometriosis tracking apps, we checked each one against the same checklist: pain location and severity tracking, flare and trigger logging, medication and surgery history, doctor-ready export, and privacy. For each app we reviewed its current App Store listing, published pricing, privacy policy, and recent user reviews. Veya is our own app; we held it to the same checklist and note where competitors are stronger.

Why is endometriosis tracking different from period tracking?

Tracking endometriosis isn't like tracking a regular cycle. Here's what to look for in an app:

Pain Tracking With Real Detail

"Did you have pain today: yes/no" doesn't cut it. Endo pain has location (pelvic, lower back, leg, bowel), severity (a 4/10 day is very different from a 9/10 day), and quality (sharp, cramping, burning, stabbing). Good endo apps let you log all of these so you can see how your pain actually moves, not just whether it happened.

Flare Logging With Triggers

Endo flares can last hours or days, and they often have triggers: certain foods, stress, exercise, lack of sleep, ovulation, the days before your period. Logging what happened in the 24 to 48 hours before a flare is how you start finding YOUR triggers, not someone else's.

Medication and Surgery History

If you're on hormonal suppression (combined pill, progestin, GnRH agonist), tracking how your symptoms respond over months is genuinely useful. Same for supplements (magnesium, omega-3, NAC, turmeric) and pain medication. If you've had excision or ablation surgery, an app that lets you mark that date and track symptoms before vs after gives you long-term outcome data your surgeon will care about.

Pattern Recognition Over Months

Endo symptoms shift across cycles, seasons, and life stages. A weekly snapshot won't show you whether your flares are getting more frequent. Look for apps that visualize trends over months and years, not just days.

Doctor-Ready Reports

You'll be in a 12-minute appointment with a clinician who may not be an endo specialist. "I've been in pain a lot" is easy to dismiss. "I had 14 pain days last month at an average severity of 6/10, with three flares lasting 24+ hours triggered by ovulation and red meat" is harder to brush off. Apps that export clean reports are worth having.

Wearable Integration

Some people notice sleep disruption or changes in resting heart rate and HRV around flares. Wearables capture this automatically. If you already wear an Apple Watch, Oura Ring, or Garmin, an app that syncs with your device adds objective data without extra logging work.


Which endometriosis tracking app fits which need?

For Dedicated Endo Research: Phendo

Best if you want: A tracking app built specifically for endometriosis, developed by Columbia University researchers. If iOS-only is a sticking point, Veya also runs in a browser, and the web app page explains how.

Key Features

  • Designed specifically for endometriosis tracking from day one
  • Daily logging of pain, mood, energy, GI symptoms, sleep, and bleeding
  • Daily questions about activities, energy, and mood[5]
  • Self-management tracking (medications, supplements, heat, exercise)
  • Lets you review tracked data with your care team[5]
  • Data contributes to ongoing endo research at Columbia
  • Completely free, no premium tier

Strengths

  • Academic credibility. Built by Columbia University's Department of Biomedical Informatics
  • Endo-first design. Every field exists because endo patients said they needed it

  • It goes beyond pain: it also asks about energy, mood, diet, activity, and what you did to manage symptoms[5]
  • Free to use
  • Cross-platform (iOS and Android)

Limitations

  • Less polished interface than commercial apps. Functional, not glossy
  • No cycle prediction or fertile window tracking. It's a symptom tracker, not a period tracker
  • No wearable integration
  • No nutrition or fitness tracking beyond simple logs
  • Smaller user community than mainstream apps
  • Updates are research-paced, not commercial-paced

Who Should Choose This

Phendo is ideal if you:

  • Want an app designed specifically for endometriosis, not adapted for it
  • Care about contributing your data to endo research
  • Want everything free with no premium upsell
  • Prioritize substance over interface polish

  • Pain intensity, location, and quality tracking
  • "Impacts" view shows correlations between tracked factors and symptoms
  • Medication, supplement, and treatment logging
  • Mood, energy, sleep, and food trigger tracking
  • Weekly reports with customizable graphs
  • Data export for healthcare providers
  • Syncs steps, sleep, and heart rate through Apple Health[6]

Strengths

  • Highly customizable: you can build your own symptoms and factors, which suits a condition that doesn't fit a template
  • Rated 4.8 out of 5 from about 6,500 App Store ratings, and its listing says over 2 million patients and doctors use it[6]
  • Built for chronic-condition tracking, so it adapts to endo
  • Correlation engine surfaces patterns like "pain is worse on weeks with under 6 hours sleep" or "flares cluster around ovulation"
  • The developer says health data is encrypted and will never be sold; its privacy label also lists identifiers and contact info used for tracking, so read the policy[6]
  • Cross-platform (iOS and Android)

Limitations

  • Not designed cycle-first. Period tracking is a module, not the core. If you want detailed cycle predictions or fertile window tracking, you'll need a separate app
  • Interface can feel overwhelming because there are so many options to configure
  • No nutrition tracking with calorie/macro detail (only trigger logging)
  • Some reporting and export features may sit behind Premium, so check before relying on them

Who Should Choose This

Bearable is ideal if you:

  • Have a complex endo presentation and want to track everything
  • Want to find your specific triggers (foods, stress, sleep, hormones)
  • Already use it for other chronic conditions (PMDD, IBS, migraines often co-occur with endo)

  • Nutrition tracking helps you spot food triggers (some people notice links with foods such as dairy, gluten, red meat, or alcohol)
  • No ads, no data selling
  • One app instead of three saves daily friction during a flare week

Limitations

  • iOS only. No Android version yet
  • Newer app with a smaller endometriosis-specific community than Phendo or Bearable
  • Full AI features require premium ($9.99/month or $49.99/year as of October 2026)[16]
  • Not endo-first by design. It's an all-in-one health app that handles endo well, not a dedicated endo app like Phendo
  • Fewer pre-built pain-quality options than Bearable

Who Should Choose This

Veya is a good fit if you:

  • Want to understand how diet, sleep, exercise, and your cycle affect your endo symptoms
  • Already use a wearable and want that data connected to your symptom logs
  • Want one app instead of juggling a symptom tracker, a food log, and a cycle app
  • Want to bring organized data to doctor and surgeon appointments

Pricing: Free (most features), Premium $9.99/month or $49.99/year for full AI insights and advanced correlations (App Store listing, as of October 2026).[16] For a closer look at what the app tracks for endometriosis specifically, see our endometriosis tracking features.

How do these apps handle your endometriosis data?

Endo data is deeply personal: pain patterns, surgery dates, hormone use, fertility status, and intimate symptoms. Here's how each app handles it:

  • Embody takes a local-first approach: the company says data stays on your device and is encrypted, and its open-source release is still planned, so the claims can't yet be checked in code.[13] Its App Store privacy label also reports some usage analytics.[14]
  • Phendo is a Columbia University research app, and your tracked data contributes to endometriosis research. Its App Store privacy label lists health data as not linked to you; read its privacy policy before joining.[5]
  • Bearable says its health data is encrypted and that it will never sell your data. Its App Store privacy label also lists identifiers and contact info as used for tracking, so read the policy.[6]
  • Clue is Berlin-based and says EU data protection law applies to its users, including in the US.[12] Its App Store privacy label also lists health data as linked to your identity, so read the policy.[11]
  • Veya doesn't sell data to third parties and doesn't show ads.
  • Stardust's App Store description says it never sells or shares personal health information, while its privacy label lists identifiers, purchases, and usage data as used for tracking and third-party advertising, so read the policy.[15]
  • Flo has a complicated history. Settled with the FTC in 2021 over sharing data with Facebook and Google; that order requires an independent privacy review.[9] Flo, Google, and Flurry also agreed to a $59.5 million class settlement, with preliminary approval in April 2026 and a final approval hearing on October 29, 2026.[10] Flo has since added Anonymous Mode.

How do you get the most out of endo tracking?

Whichever app you choose, here's how to make tracking actually move the needle:

  1. Track every day for at least 3 cycles. Endo patterns emerge slowly. Two weeks of data won't tell you much. Three months will start showing you what's cyclical, what's constant, and what your triggers are.
  2. Log pain by location and severity, not just yes/no. "Pelvic pain 7/10" is useful. "Bad day" is not. The detail is what turns vague memory into evidence a doctor can act on.
  3. Note what happened in the 24-48 hours before a flare. Food, sleep, stress, exercise, sex, cycle phase. Triggers hide in the lead-up to a flare, not in the flare itself.
  4. Track medications and surgeries with start dates. "Started 20mg progestin on March 1" plus three months of symptom data tells you whether it's working. That's the kind of thing your gynecologist actually cares about at follow-up.
  5. Bring tracked data to every appointment. Endo is still dismissed. A printout that says "14 pain days last month, average severity 6.5/10, 3 flares lasting 24+ hours" gives your doctor something concrete. It's much harder to say "it's just stress" against data.
  6. Don't aim for perfect logging. A quick daily check-in beats a perfect entry you skip half the time. If you miss a day, log "no symptoms" or "didn't track" and move on. Consistency over completeness.

Pro Tip

If you're not sure which app to start with, try Phendo if you want endo-specific structure or Bearable if you have complex symptoms and want maximum flexibility. Both are free. If you want pain tracking connected to nutrition, sleep, and a wearable, Veya covers more ground in a single app. The most important thing is to start now, not to pick the perfect app.

Frequently Asked Questions

What should I look for in an endometriosis tracking app?

Look for an app that lets you track pain by location and severity (not just yes/no), logs flares with triggers and duration, tracks medications and surgeries over time, shows patterns across your cycle (not just within one period), and lets you export a clean report for doctor appointments. Custom symptom categories matter because endometriosis presents differently for everyone.

Is there a free endometriosis app?

Yes. Phendo, built by Columbia University researchers, is free and endo-specific. Bearable is free to start, with customizable symptom tracking that suits endo. Veya provides free symptom, cycle, nutrition, and wearable tracking. Embody is free to start, with paid membership tiers. Clue and Flo offer free basic tracking, with more advanced features behind paid tiers.

Can a regular period tracker handle endometriosis?

Most struggle. Standard period trackers focus on predicting your next cycle, not on the pain, flares, and surgical history that define endo tracking. Some apps like Flo have added endo-specific symptom checkers, and Clue's 200+ symptom range works for endo. But dedicated apps like Phendo and flexible chronic-illness trackers like Bearable give endo patients more useful data than period trackers alone.

How can tracking help me get diagnosed with endometriosis?

Endometriosis often takes years to diagnose (the WHO puts the average at 4 to 12 years),[1] partly because pain is subjective and easy to dismiss. Tracking gives you objective data: how many days per month you're in pain, how severe it gets, what triggers flares, and how much it disrupts work and sleep. Bringing a 3-month tracked record to a doctor's appointment is much harder to dismiss than describing pain from memory. And as of March 2026, ACOG's guideline says a clinical diagnosis from symptoms and an exam is enough to begin treatment without a diagnostic laparoscopy first.[3]

Which endometriosis app has the best privacy?

Embody is the most local-first option here: its developer says data stays on your device and is encrypted, though its open-source release is still planned. Phendo is a Columbia University research app; read its privacy policy. Bearable says it encrypts health data and never sells it. Veya doesn't sell data or show ads. Clue is Berlin-based and says EU law applies to its users. Flo has a more complicated history including a 2021 FTC settlement and a pending $59.5 million class settlement, though Anonymous Mode has been added since.

Should I track endometriosis with a wearable?

Wearables add useful objective data for endo tracking. They can capture sleep, HRV, and resting heart rate automatically, which some people line up against their pain logs. If you already own an Apple Watch, Oura Ring, or Garmin, look for an app that pulls that data in alongside your symptom logs.

Final Thoughts

There's no single "best" endometriosis app, because endo itself presents differently for everyone. Some people have severe pelvic pain a few days a month. Others have constant fatigue, GI symptoms, and fertility concerns. What matters is finding a tracker that handles YOUR presentation and helps you build the evidence base your medical team needs.

If you want an app designed for endo from day one with academic credibility, Phendo is endo-specific. If your endo is complex, Bearable offers 200+ symptoms plus unlimited custom categories. If you're earlier in the diagnosis process, Flo's Symptom Checker can help guide doctor conversations. If you want lots of pre-built symptoms, Clue has 200+ options. If privacy is non-negotiable, Embody runs local-first, with an open-source release planned. If you want a clean design for simple daily check-ins, Stardust covers that. And if you want to track pain alongside your cycle, nutrition, sleep, fitness, and wearable data together, Veya covers a lot of ground in a single free app.

Pick one. Track for 3 months. Bring the data to your next appointment. You're not going to fix a diagnosis delay that can run for years overnight, but you can absolutely change how the next conversation with your doctor goes.
