cares health notebook
I am Koko. I stay beside you and look after your notes.
Facing illness every day —you don't have to carry it alone.
A short note each day becomes a way to look back on how you've been, and a way to tell your doctor how things have gone. We look at it with you.
You are welcome here even without a firm diagnosis, or when tests keep coming back normal.

What your records start to show
Notice the changes you hadn't noticed.
Describing how you've been from memory alone is hard. We set your daily notes beside your sleep and activity, and look at what came before and after the hard days and the easier ones.
Find clues in daily records to reflect on how your condition and daily life overlap. Correlation does not establish a cause or treatment effect.
Kept at the moment you answered.
We ask how you are right now, so each entry keeps its exact time. Later you can line up the waves within a day, and what came together before a day that suddenly got worse.
The cards below are made-up examples. Whether a possible link appears, and what is shown, depends on how much you record and what you record.
Sleep, and the next day
On the day after a night with less sleep than usual, we line up from your own records how you felt.
Around a hard day
Look back at the days around a hard day, side by side with days that felt easier. What you can see depends on how much you record and what you write.
Before a sudden bad day
Once you have logged three sudden bad turns, you can look back at the times of day they tend to happen and how they line up with the night's sleep before.
A few words are enough.
Body, mood, meals, medicines and sleep, in a few words or a photo. You get a reply that meets what you wrote, and insights from the next day on.
This screen and the chart above are examples. Your own records never leave your account.
One step ahead
The next step that may suit you, ready ahead of time.
From your records and new research around the world, we offer a small step you can take today. The decision is always yours.
Suggestions shaped around you
From food, sleep and movement to Eastern self-care and new research. Each comes with how certain it is, brought down to a step you can manage.
A heads-up on the weather
Set your area and we let you know on the home screen ahead of days when pressure or temperature shift sharply. How it affects people varies.
On days when getting out is hard
We show ways to see a doctor from home, and how to put together the records to hand over. cares itself does not diagnose or prescribe.
One page to tell your doctor how it went
When, what, how much, and how it changed. Your records laid out as they are, ready to bring to your appointment.
Real providers
Suggestions lead on to clinics and services we have checked on their official pages. Referral fees never change what we list or the order we show it in.
Please keep taking the medicines and treatment you are on. If strong symptoms come on suddenly, don't wait here: call emergency services or go to an emergency department right away.

Questions people often ask before starting.

Yes. You can leave from Settings at any time. Before you go, you can export everything you wrote. Leaving deletes your records.

How long until I learn something?
Try recording for about two weeks, at a pace that suits you. What you can look back on depends on how much you record and what you record. Two weeks is not a guarantee of insights or of feeling better.
Does it cost anything?
If anything about how cares is offered changes, we will always tell you in advance.
Does it replace treatment at a hospital?
No. It does not diagnose or tell you what medicine to take. It is a tool that supports your care through daily records and organised information. You can put your course on one page and take it to your appointment.
What we hope for
We work toward remission for everyone in the world living with chronic illness.
Through two years living with ME/CFS, my daily records became my strongest tool.
Three things the developer held onto through his own illness
- Never leave it all to the doctor: see it as a joint project between yourself, the patient, and your doctor.
- Keep watching the newest medical knowledge around the world, and consider every approach, Western or Eastern.
- Take notes on how you feel every day, learn your own pattern of flare-ups and cycles, and act on it.
The developer's own story of making records his tool.
Start with a few words about today, at your own pace, for two weeks.
Timestamped notes and numbers help you explore possible associations between daily life and how you feel, alongside device and environmental records where available.
A health notebook for reflecting on your experience together with your clinician. Two weeks is a starting point, not a promise of insights or symptom improvement. Cares does not replace medical advice, diagnosis or treatment.
