cares

For people with chronic conditions
Track your health, organize your information

We work toward remission for everyone in the world living with chronic illness.

That is our mission. cares does not replace medical care; it supports the daily steps of recording, noticing, and trying that bring remission closer.

Uncovering the causal links and worsening patterns in chronic illness that are invisible to both you and your doctor.

As your daily records add up, the connections between symptoms, food, sleep, mood, and environment come into view. Every few days we re-read them from a fresh angle and offer the next step.

From the cares team, to those just arriving

Hello. cares is a service built in the hope of making daily life a little lighter for people living with conditions that have no clear cause. Your records belong to you. They are stored encrypted and are never used for ads or shared with anyone. If cares turns out not to be for you, you can take all of your data with you and erase it without a trace, at any time. On hard days, a single line is enough. Shall we start with just one note about today?
