Built with you at the centre.
Yarn was shaped through conversation.
Yarn was designed through consultations with people living with chronic conditions, and created with clinicians working within real time pressures.
Your health happens between appointments.
Yarn helps you hold onto it.
01/03
Healthcare is built around isolated moments, while life happens in between.
So much can change between visits, yet appointments give you only minutes to explain what matters.
Yarn helps you capture your experience over time, so nothing important is lost.

You're not imagining it.
Appointments can feel unfinished.
- You forget evertything that's been happening day-to-day
- You replay the appointment afterwards.
- You second-guess yourself and wonder if you made sense.
- You remember what you missed on the journey home.
"It's up to you to be as clear as you can be in an appointment, which can be challenging in itself."
Vicky GrandonNumerous chronic conditions
"When you get to see a doctor nowadays, it's such a special treat — they're really busy and you know you won't be able to come back immediately. You really want to get the most out of your appointment. "
DanChronic Ear Ache
"When you're in there and the doctor's talking, it's so hard to remember. What do you want to talk about?"
JanetChronic arthritis
"It doesn't feel like I'm always being coherent with Doctors. Sometimes I get emotional... I then struggle to articulate things."
SarahSecondary Auto-Immune Conditions
"I am mindful that sometimes after an appointment I think, oh damn, I didn't ask about X or Y. I'm so busy talking, I might not have noticed that I've missed something. "

What if appointments didn't rely on your memory?
What if your experience was clear before you walked in the room?
What if those ten minutes could focus on answers, not catching up?
What if appointments didn't rely on your memory?
That's why we made Yarn.
Yarn is an app that helps people living with chronic conditions capture their health between appointments. Using a simple voice and text chat, users describe their experience in their own words. Yarn turns those moments into a clear summary for their next appointment.
Capture
Record what matters, when it happens.
Short notes in your own words. No pressure to log everything. Just what felt worth keeping.
FeaturesPatterns
See your journey take shape.
Over time, patterns begin to appear. Not noise. Just the shape of your experience, gently surfaced.
FeaturesClarity
Walk into appointments with clarity.
A calm summary of what has been happening. Context, not chaos. Ready before you see your doctor.

"Knowing I would have to log my day in the app made me more conscious of taking care of myself and planning ahead."
"Yarn doesn't feel like you're talking to a machine. It really listens, remembers what you've said before, and asks thoughtful, relevant questions about how you've been feeling."
"I think it's a very seamlessly integrated platform. It's very easy to use. You just literally speak at your phone and the recognition of what I was saying was 100% accurate."
"Using yarn has improved my ability to understand and articulate my health condition"
"This easy to use app helped me to reflect on and record symptoms and developments in my long-term chronic illness."
"It's the fact that it makes me remember more and more stuff about my current condition because it's a conversation."
"I use it at the end of the day to summarize everything, and it was particularly helpful for tracking the specific symptoms of a new medication I just started."
"Yarn helped summarise and communicate the full picture of how my headaches affect my day-to-day life."
"Yarn immediately felt comfortable to use. The conversational style for recording symptoms and thoughts about my health was ideal."
"Yarn acted as that grounded validation to my resilience and my ability to pick myself back off the floor and dust myself off."
"Yarn has the facts, and the backup to the facts, and the pattern that has led up to those facts - all available easily."

The people behind Yarn
We're a team of five Design Engineers from Imperial College London. Several of us have navigated chronic conditions ourselves, so this isn't abstract for us. We started Yarn because we understood the problem before we tried to solve it — and we're building it alongside the clinicians and patients who live inside it every day.

GP with 30+ years' experience, specialising in women's health and mental wellbeing.
Dr Suzie
"You'll often be halfway through and think, 'hang on, no one's actually diagnosed you with IBS — you're just telling me you've got IBS.' You have to always start from the beginning of the symptoms."
Mens Health Advocate. Ai for good protagonist. Ex Microsoft. Second time founder
Tristan Taylor
"The clinical and the diagnostic world is broken. It's very peristaltic and it starts, stops and there's no viewpoint or insight into the welfare of the individual in between those diagnostic points or stamps in time."
GP with 30+ years' experience, Surrey
Dr Laura
Factors that aggravate or relieve a symptom — if you ask 'is it aggravated on exertion?' they'll look at you blankly. You have to make it real: 'Do you get it when you're running the Hoover?'
Professor at Imperial College London. Researcher in AI and technology for mental health and wellbeing.
Rafael Calvo
Rafael A. Calvo internationally recognized and cited for his work in design research, Human-Computer Interaction and Intelligent Systems. He focuses on systems for learning, wellbeing and health.

Dr Sylwia
"I have not seen the chronic conditions diaries on the NHS app. There is quite a lot of room for putting new diaries, new sorts of software into the system."
Researcher in human–computer interaction and AI. Addresses challenges in health and well-being.
Dr Tao Bi
"Through self-reporting, people gain greater self-reflection and self-awareness. They develop a more holistic understanding of when pain might occur and how they respond to it. This level of self-learning is one of the primary outcomes or benefits."
Long-time activist, researcher, and advocate for social justice. Sufferer of chronic conditions.
Vicky Grandon
"Yarn gives you the space that you find difficult to create for yourself — to explore what's going on with your physical health."
