Patterns & Trends

Eggs and joint pain two days later

Higher joint pain was recorded two days after eating eggs on 8 of 10 occasions.

On comparison days without recorded egg consumption, higher joint pain occurred on 2 of 10 occasions.

Fictional example. This association does not establish that eggs caused the change.

Daily Capacity

Your capacity appears reduced today

Your recorded fatigue is higher than usual, your sleep was shorter, and yesterday’s activity added to your recent load.

You may want to leave more space between activities and keep plans flexible.

Illustrative example using fictional data. A pacing estimate—not a medical prediction or a measure of safe activity.

Your health doesn’t happen in isolated days

Some changes are obvious. Others only become noticeable when you look back across days or weeks.

When symptoms and energy shift, it can be difficult to see how sleep, activity, stress and personal circumstances fit together—or to decide what feels realistic today.

Chroniqa brings those records together, helping you explore your own patterns and build a clearer picture over time.

A clearer picture. More informed planning.

A daily estimate, with the reasoning included

Your current symptoms are part of the picture. Recent sleep, activity and changes in your health provide context.

Chroniqa brings that information together into an explainable pacing estimate—one input to help you consider what feels realistic today.

Built for life with chronic illness

Whether your symptoms fluctuate, your capacity varies or your health changes gradually, Chroniqa helps you keep track of your experience over time.

It is designed for people living with conditions such as ME/CFS, Long COVID, fibromyalgia, POTS, multiple sclerosis (MS), autoimmune conditions, chronic pain and other chronic or progressive illnesses.

You do not need a particular diagnosis to recognize yourself here. What matters is whether understanding changes, personal patterns and daily capacity would be useful in your life.

Created from lived experience, shaped by professional expertise

Chroniqa began with a personal need: to make more sense of changing symptoms and plan life around limited, unpredictable capacity.

Its founder, Charity de Vries, lives with severe chronic illness. She brings extensive experience in life-sciences and healthcare language work, including the linguistic aspects of life-sciences software and systems, alongside her background in quality management, entrepreneurship and full-stack software development.

That combination shapes Chroniqa’s focus on understandable information, transparent explanations and respect for the person behind the records.
