Best Endometriosis Apps for 2027: Symptom Trackers Compared

If you're trying to get endometriosis taken seriously or diagnosed, pick an app that builds the full record your gynecologist needs: where it hurts, how bad it gets, what you ate, what sets it off and what you've tried. Endolog is made for exactly that, with pain logs, a food diary, bowel and period logs and a PDF report for your specialist (full disclosure: it's our app). Bearable is a general symptom tracker, QENDO is a free endo app, and Phendo sends your logs to endo researchers.

We wrote this for 2027, so these are the endo trackers we'd look at heading into the new year, and what each one does. Every app detail was checked on 1 November 2026.

Which endometriosis app should you choose?

• You suspect endo (or have it) and want a record that holds up at the gynecologist, food included: Endolog. It keeps pain location on a pelvic body map, flares, food, stress, bowel changes, bleeding and treatments in one daily record and exports a PDF for your specialist. It's built for before a diagnosis as well as after.
• You track several conditions and want to compare them with other factors: Bearable. You set up your own symptoms and factors (sleep, food, stress, meds), and it shows how they line up with bad days.
• You want a free endo app with no paid tier: QENDO, from an Australian not-for-profit.
• You'd like your logs to help endo research: Phendo, from Columbia University's Citizen Endo project.
• You're on Android: Bearable, QENDO and Phendo all have Android apps. Endolog is iPhone and iPad only.

How we compared them

We read each app's own App Store listing and website on 1 November 2026 and wrote down what each one says you can log, what you can export, and what costs money. We didn't count anything we couldn't find written down. "Not listed" in the table means we couldn't confirm it, not that the feature is missing. We read the US App Store listings, except QENDO, which we could only find in the Australian App Store.

We make Endolog, so we've tried to be extra strict with ourselves: every Endolog line below comes from our public App Store listing, and we say where another app does more.

Bearable: a general symptom tracker

Bearable isn't an endo app. It's a general symptom tracker for any chronic condition, so it can cover endo together with other things such as gut trouble, fatigue, migraines or mood. You set up your own symptoms and factors, and it shows how things like sleep, food, stress and medication line up with how you feel. You can log pain level, where it hurts and how long it lasts, plus digestive symptoms and cycle phases.

• Free: unlimited custom symptoms and moods, weekly reports and a customizable graph.
• Paid: a $34.99 subscription that's often discounted. It adds correlation reports, experiments, and your history beyond the last 30 days.
• Export: you can export your data and reports from inside the app.
• The catch: you set it up yourself, and it doesn't come with an endo-specific symptom list or a body map.

QENDO: a free endo app from a not-for-profit

QENDO is made by an Australian not-for-profit that supports people with endometriosis, adenomyosis, PCOS and pelvic pain. The app is free, and its listing says it will stay 100% free. You can log pain, fatigue, bloating, mood, sexual pain, GI symptoms, meds, triggers and bleeds, mark flare days, and save notes and questions for your GP or specialist. You can also turn cycle tracking off.

QENDO got the highest quality score of 19 endometriosis apps in a 2025 review, and Bearable came second.

• The catch: we could only find it in the Australian App Store, so check whether it's available where you live. Its listing doesn't mention a PDF or file export.

Phendo: a research app

Phendo comes from Citizen Endo, a research project at Columbia University. You log symptoms from pain intensity to endo belly, plus what you tried (diet, exercise, medication) and whether it helped, and your data goes to researchers studying endo. It's free, you need to be 13 or older, and under-18s need a parent's consent.

• Sharing: you can explore your data with your care team. We didn't find a PDF export listed.
• The catch: it's a research tool first, so you get less personal analysis back than with Bearable.

Endolog: built to document endo toward a diagnosis

Best for: anyone who suspects endometriosis (or has a diagnosis) and keeps hearing "where does it hurt, how often, what makes it worse, and what have you tried?"

Full disclosure: we make Endolog, and we built it for one job: helping you build the record your gynecologist needs to take your symptoms seriously, whether you're still pushing for a diagnosis or managing endo after one. It works for endometriosis, adenomyosis, PCOS, IBS and chronic pelvic pain.

What you log: pain intensity from 0 to 10, location on a pelvic body map, what it feels like and when it happened, plus other symptoms such as bloating, fatigue, migraines and painful urination. You also log your period and spotting, bowel movements, stress, meds and supplements, and TENS sessions. Logging stress next to your symptoms helps you see whether hard weeks line up with flares.

Food and your symptoms: the food diary records what you ate and when, what you noticed after (say, bloating or cramping), how you felt after the meal, and an optional photo and note. Your PDF report then lists the foods you ate on the same days as your pain, with the average pain on those days, next to your pain on period and non-period days and on days with bowel symptoms. It doesn't prove a food causes your pain, but it gives you and your doctor a pattern to look at.

For the appointment: export a PDF report for your doctor or specialist, so the conversation starts from months of entries instead of a guess. An app can't diagnose endometriosis. What it can do is help you show up with a clear history of what's been happening. The step-by-step guide to tracking endometriosis symptoms shows what to log each day.

• Privacy: your data is encrypted, and we don't sell it.
• Compared with Bearable: Bearable's correlation tools are broader if you track lots of conditions. Endolog keeps everything inside an endo-specific record (body map, bowel and bladder symptoms, food, stress, period) that you can hand to a gynecologist.

What to look for in an endo tracker

• It's built around pain, not only your cycle. Period trackers like Flo or Clue are built mainly to predict your cycle. That's useful, but they're not designed around chronic pelvic pain.
• It works without a cycle. If your periods are irregular, or you're on hormones that stop them, the app should still let you log every day.
• Pain as a number, plus where it is. "Bad" doesn't show your gynecologist the difference between a 4 in the morning and an 8 at night, or pain that moves down one leg.
• Room for the non-period stuff: bowel pain, bladder pain, endo belly, fatigue, pain during sex.
• A treatment log. What you took, when, and whether it helped.
• An export a busy doctor can actually read. A one-page summary beats scrolling through your phone in a 10-minute slot.
• Privacy you can read. Check whether your data is encrypted, stays on your device, or goes to researchers, and pick what you're comfortable with.

Getting the most out of your log at the appointment

Whatever app you pick, the hard part is turning weeks of logs into a 10-minute conversation. Our pain diary guide has a free printable if you'd rather use paper, and what to bring to your gynecologist appointment covers the rest. If you're not sure how to put your pain into words, try our period pain scale.

FAQ

What's the best app to track endometriosis toward a diagnosis in 2026-2027?

Pick one that logs pain severity and location, gut and bladder symptoms, what you ate and what you tried, and exports a report. Endolog is built for that (it's ours). Bearable and QENDO are other options, and both are free to start.

Which endometriosis app helps find triggers?

Bearable correlates the symptoms and factors you set up (full reports are in its paid tier). Endolog connects symptoms to your cycle, food, digestion, stress and treatments, and its PDF report puts your pain next to your period, bowel symptoms and the foods you ate that day. QENDO lets you log triggers on flare days.

What is the best free app for endometriosis?

QENDO and Phendo are both free, with no paid tier. Bearable has a free version with an optional subscription.

Is Bearable free?

Yes, Bearable has a free version with unlimited custom symptoms, weekly reports and a graph. Its optional subscription costs $34.99, is often discounted, and comes with a 7-day free trial. The subscription adds correlation reports, experiments and your history beyond the last 30 days.

Which endometriosis app can make a report for my doctor?

Endolog exports a PDF report for your doctor or specialist. Bearable lets you export data and reports, QENDO has appointment notes and questions, and Phendo lets you review your data with your care team.

Is there an endometriosis app with a body map?

Yes. Endolog logs pain location on a pelvic body map.

Is a period tracker app enough for endometriosis?

Usually not. Period trackers like Flo or Clue are built mainly to predict your cycle. That's useful, but they're not designed around chronic pelvic pain, so they often have no place for pain on non-period days, bowel or bladder symptoms, or what you tried and whether it helped.

Can an app diagnose endometriosis?

No. A tracker helps you build the record your gynecologist needs to look into it properly. It doesn't diagnose anything itself.

Do I need to track my period to use these apps?

Not with all of them. QENDO lets you turn cycle tracking off.
