Emenla is a record of endometriosis kept in your own words. Say what you feel, see it named in clinical language, count what you logged against your periods, and walk into the appointment with one clear page.
Your words, their words
Your words, their words.
Tell it in your own words. We'll find the clinical name for it.
You write what you feel. Emenla matches it to the term a clinician would recognise, shows you where that term comes from, and keeps your own sentence printed right beside it. A clinician can check the match at a glance. So can you.
Emenla names symptoms in clinical language. It never names a condition.
-
Your words: It hurts when I go to the bathroom, especially during my period.
In clinical language: Dyschezia
pain on defecation
-
Your words: Period pain. Menstrual cramps.
In clinical language: Dysmenorrhoea
painful menstruation
ICD-10 N94.6
-
Your words: Painful sex.
In clinical language: Dyspareunia
pain during or after intercourse
ICD-10 N94.1
Every term is taken from the ESHRE 2022 and NICE NG73 guidelines. See the sources

Press and hold. Your sentence writes itself, and the clinical term appears beside it. Let go early and it un-writes.

The word "cyclical" is never taken from a sentence. Emenla only uses it after counting your logged days against your logged period starts. Concepts come from your words. Qualifiers come from your data.
Other apps turn a symptom log into a document for a clinician. What Emenla does differently is print your own sentence beside every clinical term, with its source, and refuse to say "cyclical" until it has counted.
Inside Emenla
What's in the app.
Record
Tap where it hurts, or say it out loud. A few words is a complete entry.
Your document
A page for your appointment, each clinical term with your own words beside it. Shown here with invented sample entries.
See the sample page
Overview
Counts of what you wrote down. No score, no streaks, no verdict on your day.
Assistant
Tell it what happened in a sentence. Nothing is saved until you confirm it.
Questions to ask
Write what you want to ask. Analyze offers a clearer version, and your words stay until you choose.
Also inside: detail for each symptom if you want it (where exactly, what it felt like, when it started), Learn, short plain-language reads you can also listen to, and Community, which for now is a preview: nothing in it is sent or received. Nutrition and Fitness are there too, in an earlier form than the rest.
iPhone Duo
Made for iPhone. iPhone Duo is next.
Every app screen on this page is from iPhone. Emenla will come to iPhone Duo later, and its display opens wide enough for your record and your document side by side. The two Duo screens here show the app's launch screen, because this page shows only what is real.
How it works
Three things it does.
01
A few words is enough.
Type or speak. "Bad cramps, back pain, stayed in bed" is a complete entry. Add severity and a period start if you want to. Skip everything else.
02
See what you logged.
Counts from your own entries. Which days, how often, how bad, and how that lines up with your logged periods. Nothing scored, no streaks.
03
Walk in with proof.
A one-page summary in clinical terms, with your own words printed beside each one, for you to bring to your appointment. What it is for is you feeling clear about your own body. Whether a clinician reads it is up to them.
History
A long time to be believed.
Three centuries from the first description to a guideline that says your symptoms are enough.
The moments from 1690 to today, with the years that passed between them.
170 years pass.
1860Seen
Seen under a microscope.
Karl von Rokitansky in Vienna identifies tissue like the lining of the womb growing where it should not.
Sixty-seven more.
1927Named
Given its name.
John Sampson coins the word endometriosis and proposes that backward menstrual flow seeds the tissue. Still the leading theory.
Another fifty-three.
1980Organised
1stpatient-led organisation
Patients organise.
The Endometriosis Association is founded in Milwaukee, the first patient-led organisation, and starts collecting women's own accounts.
2005Guided
The first European guideline.
ESHRE publishes its first guideline on diagnosing and treating endometriosis, updated in 2014 and 2022.
2014Marching
Patients take to the streets.
On 13 March 2014 the first Worldwide EndoMarch brought patients onto the streets of cities on several continents. March has been Endometriosis Awareness Month since 1993, and the colour it wears is yellow.
2017Heard
Clinicians are told to listen.
The UK guideline NG73 tells clinicians to suspect endometriosis when a woman reports pelvic pain, period pain that disrupts daily life, or pain during sex.
2026Enough
Enough.symptoms · history · examination
Your symptoms are enough.
ACOG's guideline says a clinical diagnosis from symptoms, history and an examination is enough to begin treatment. Surgery is not required first.
TodayStill waiting
Four to eleven years.
Studies still put the delay between first symptoms and a diagnosis at four to eleven years. Emenla is for the years in between.
Told out loud: EndoTV, Living With Endo, Voices and Visions, NICE on its guideline and Get Loud, a TED talk.
Privacy
Your record stays on this phone.
Your entries are not uploaded to a server, not sold, and not shared with anyone. Emenla asks for an account so you can get back in, and the account holds your email address and nothing from your symptom record.
- Your symptom record lives in the app's own private on-device database, and nothing sends it anywhere.
- Speech recognition runs on the device. No audio leaves the phone and no recording is kept.
- Photos you attach to an entry are copied into the app's private storage. They are never uploaded and never written back to your photo library. The one exception is a meal photograph you ask Nutrition to read, below.
- No analytics of any kind. No ads, no ad identifiers, no third-party trackers, no crash reporting, no remote configuration, no tracking prompt.
- The account holds your email address, plus the nutrition figures for any meal you ask it to read. It does not sync, back up or transmit anything you record about your body.
- Notifications are local only. No push service, no device token.
- What can leave the phone, said plainly. Three features send something to OpenAI or Anthropic to be read, and none of them is on until you say yes. Each asks once, the first time you use it, and each has its own switch in the app under What Emenla can reach. Under 16, a parent or guardian needs to agree first.
- Reading a meal: the photograph goes through our server in Frankfurt to be read, and four nutrition figures come back and are kept with your account. The photograph is never stored on a server.
- The assistant: what you write goes so it can answer, with your first name and the names of your symptoms. Your record never goes with it, and your messages are not stored.
- Stronger questions: when you tap Analyze, the questions you wrote for an appointment go, with your symptom names and a few sentences the app counted from your record. Your entries stay on the phone, and nothing lands on your page until you tap it.
- An appointment you add to your calendar goes to your calendar app, which may sync it to iCloud or Google. Emenla can add an event and cannot read your calendar.
- The optional summary export is an Apple in-app purchase handled through RevenueCat, which receives an anonymous purchase identity and your purchase status. It never receives your symptoms, notes, photos, cycle dates or your name.
- Under GDPR, health data is special category data under Article 9. That is exactly why your record is not on a server of ours. What we hold is your email address, the nutrition figures for meals you ask it to read, any feedback you send us, and a timestamp each time you use the assistant or Analyze, never what you wrote.

Everything you need to know about Emenla.
Short answers, in plain words. If yours is not here, ask.
Ask a questionWhat is Emenla?
Emenla is an iOS app for keeping a record of endometriosis symptoms. You log a day in a few words, typed or spoken, or by tapping where it hurts on a body map. The app counts what you wrote back to you: which days, how often, how bad, and how that lines up with the periods you logged. When you need it, it prints a one-page summary in clinical terms with your own words beside each one, to take to an appointment. Your record stays on the phone.
Does Emenla tell me whether I have endometriosis?
No, and it never will. Emenla names symptoms in clinical language and keeps your words beside each term. Whether those symptoms add up to a condition is a conversation for you and a clinician.
Is it private and secure?
Your symptom record lives in the app's own database on your phone. Your symptoms, period dates, body map and notes are not uploaded, so there is no symptom data of yours sitting on someone else's machine. Emenla does need an account, and the account holds your email address and nothing from your symptom record. Speech recognition runs on the device and no audio is kept. The app has no analytics, no ads and no trackers; this site has no cookies and no third-party fonts. A few things can leave the phone, each only when you use the feature that sends it. Three go to OpenAI or Anthropic to be read, and only after you have said yes: a meal photograph, if you ask Nutrition to read it, which is never stored on a server, though the four nutrition figures it comes back as are kept with your account; what you write to the assistant, which never includes your record; and the questions you ask Analyze to make stronger, with your symptom names and a few facts the app counted. Each of those three has its own switch in the app. Beyond them, an appointment you add goes to your calendar, and an anonymous purchase status goes to Apple and RevenueCat if you buy the optional export. The privacy policy sets out each one.
Does Emenla use AI?
Only where you turn it on. Three features use an AI model from OpenAI or Anthropic: the assistant, reading a meal from a photograph, and Stronger questions on the appointment page. Each asks you once, the first time you use it, says what it sends, and has its own switch in Settings. None of them sends your record, and none of them gives a diagnosis. The part that puts your words into clinical terms for your summary does not use them: it runs on your phone, from a fixed list of terms, each with its source.
What happens to my entries if I change phones?
You will lose them unless you export first. The account does not back up your record, so there is no cloud copy of it. Export before you switch.
Is there a streak, a score, or a daily reminder I will feel bad about?
No. There are no streaks anywhere in Emenla and there never will be. Reminders are optional and never leave your phone.
Does Emenla predict my period or my flares?
Not your flares. Once you have logged three period starts, Overview shows a range for when your next period might begin, worked out from the starts you logged and labelled as an estimate. If you turn it on in Settings, it can also show an estimated fertile window, counted from the same starts; it is off until you do, and it is not a method of contraception. Everything else is counted backwards from what you wrote.
How is Emenla science-backed exactly?
In the wording, not in a claim about your health. The terms Emenla puts on the page follow the published endometriosis guidelines, ESHRE 2022, NICE NG73 and ACOG 2026, and every figure on this site is printed with the source next to it. What the app itself does is count what you logged. Emenla has not been studied in a clinical trial, and the science page says so as plainly as it says the rest. Read the science behind Emenla.
Are you affiliated with a brand or a clinic?
No. Emenla is an independent project built in Poland, with no clinic, brand, pharmaceutical or supplement sponsor behind it, and no advertising anywhere in the app or on this site. It recommends no products and sells nothing except the optional summary export. Nothing you write is sold or used for advertising, and your record stays on your phone.
What does it cost?
Logging is free, always, and cannot be put behind a paywall because it happens on your phone: there is nothing to lock. Your first doctor summary is free. After that, the optional export is $34.99 a year or $6.99 a month, one tier, through Apple's in-app purchase.
Who makes Emenla?
An independent project built in Poland. Not a clinic, not a brand, and not funded by one. You can reach a person at hello@emenla.com.
