Preparing for launch

Your symptoms.
A clearer picture.

ENDOless is being built to help you keep track of symptoms, understand your experience over time, and prepare for conversations about your care. Starting with endometriosis.

The ENDOless app will be free.

Built around life with endometriosisYour experience comes first

Understanding endometriosis

More than
a painful period.

Endometriosis is a long-term condition in which tissue similar to the uterine lining grows outside the uterus. It can cause inflammation, scarring, and pain.

Different symptoms. Different lives.

Symptoms can include pelvic pain, painful periods, heavy bleeding, fatigue, bloating, and pain during sex or when using the toilet. Some people have few or no symptoms.

The impact can reach work, relationships, mental wellbeing, and fertility. Symptoms alone do not establish a diagnosis.

Pain that disrupts your life deserves attention.

If symptoms affect your daily life, speak with a healthcare professional. Tracking can support that conversation; it cannot diagnose endometriosis.

The value we aim to bring

From everyday experience
to useful understanding.

Our planned app turns a simple idea into practical support: a place to remember, reflect, and prepare.

Less to hold in memory.

Record symptoms, pain, and the details that matter, so your experience has a place beyond what you can recall on the day.

More context over time.

Bring individual check-ins together to explore changes in your experience, without treating a pattern as a diagnosis.

A clearer starting point.

Revisit your history and the questions you want to ask, so you can arrive at care conversations better prepared.

A look at what we’re building. Launch features will be confirmed as the app takes shape.

How it comes together

Your story,
one day at a time.

Check in.
Record what today feels like, including symptoms and context.
Build your history.
Bring individual moments together in an ongoing record.
Revisit what matters.
Reflect on your experience and prepare for care conversations.

Why ENDOless exists

Your experience deserves to be understood.

Alexandra Mont founded ENDOless after her own 16-year journey to an endometriosis diagnosis. Her experience, and the stories women have shared with her, shape what we’re building.

In more than 250 interviews, Alexandra heard about the hidden work of adapting daily life around symptoms: planning, cancellations, work, and relationships. Our ambition is to connect everyday support with information collected over time that could help women’s-health research. Read what those conversations taught us ↗

The wider picture

Women’s health.
A whole-life story.

Women’s health includes physical and mental wellbeing throughout life, beyond reproductive health alone. Bias in research and care has left gaps in how women’s experiences are understood and addressed.

That is why our mission reaches beyond a symptom log: clearer knowledge, more room for lived experience, and better-informed conversations. Endometriosis is our starting point, not the limit of our ambition.

From individual experiences to better research questions.

Alongside the free app, we’re exploring how information collected over time could help researchers understand women’s health more fully. This is a longer-term ambition, shaped by clear study purposes and informed participation.

What we stand for

The person comes first.
Always.

The principles guiding what we build, how we explain it, and the choices we make.

Listen with empathy.

Take lived experience seriously. Make space for difficult days, uncertainty, and stories that do not fit a simple score.

Respect privacy and choice.

Make data use understandable. Keep personal support and research participation distinct, with clear choices rather than assumptions.

Let evidence guide us.

Use trustworthy sources, acknowledge what is still unknown, and distinguish helpful observations from medical conclusions.

Make room for difference.

Recognize different backgrounds, bodies, and care journeys. Write clearly and design with accessibility in mind.

Privacy & informed choices

Clear questions deserve clear answers.

Health information is personal. Understanding who uses it, why, and what choices you have matters.

Start with the policy.

Our published privacy policy describes data collection, service providers and requests about your information.

What 250 conversations taught us

The hidden work of adapting everyday life around symptoms.

Is removing a name enough?

Questions to ask about health data, anonymity and research.

Understand endometriosis

An introduction from the World Health Organization.

Before we begin.

Will the app be free?

The ENDOless app will be free. You will not need a paid community supporter membership to access the app.

When can I use the app?

We’re preparing for launch and will share availability when it is ready. There is no confirmed release date to announce yet.

Who is ENDOless being built for?

We’re starting with women living with endometriosis. Our wider mission is to improve understanding of women’s health. We’ll share supported platforms and countries with the launch information.

What will ENDOless help me do?

We’re building tools for recording symptoms and daily context, revisiting your history, and preparing for care conversations. We’ll explain the features included when the app launches.

What happens when I join the community?

The signup opens ENDOless’s website community registration. It does not download the app or give immediate app access. Review the information and email options presented in the signup before joining.

Does community signup enrol me in research?

No. Joining the website community is not enrolment in a research study.

Is ENDOless a replacement for medical care?

No. It is being built to support tracking and reflection, not to provide a diagnosis or replace professional medical advice or treatment.

Where can I ask about my data?

Read our privacy policy (French) or email contact@endoless.app.

Can I discuss a partnership or research idea?

Yes. Email contact@endoless.app with a short introduction and what you would like to explore.
