Living with ME/CFS
Pacing is considered one of the most important day-to-day strategies for ME/CFS. Sam works with what your wearable already measures - resting heart rate, HRV, and sleep - compared against your personal baseline, prepared fully automatically.
Your data
Your wearable already captures them. Sam reads them from Apple Health and shows you how they shift against your personal baseline.
Sam reads the data your wearable already writes to Apple Health and compares it to your personal baseline - understandable, not a wall of numbers.
Current guidelines for ME/CFS recommend avoiding overexertion and staying within your own energy limits. Resting heart rate and HRV compared to your personal baseline can serve as an additional point of reference.
On severe days, even a chart is too much. Just ask Sam: "What's changed this week?" - and get an answer in plain sentences instead of graphs.
The monthly report captures an objective picture of your weeks - useful for doctor's appointments, applications, or simply your own memory, without having to log anything day to day.

Sam translates your numbers into clear answers and a report you can take with you.
Instead of interpreting charts, you ask questions - Sam answers from your own numbers. For example:

Further reading: what wearable data can show about everyday life with ME/CFS - and where its limits are.
ME/CFS and Long COVID overlap significantly but are separate diagnoses. Understand what distinguishes them, why ME/CFS predates COVID-19 by decades, and how post-exertional crashes affect your day-to-day.
A minimal setup guide for Apple Watch (or any wearable) when you have ME/CFS. What data matters, how to configure it with minimal effort, and how to prepare a report for your next specialist appointment.
Roughly 90 percent of people with ME/CFS in Germany remain undiagnosed. Learn what the Canadian Consensus Criteria actually require for diagnosis, and how wearable trends can support the conversation with your doctor.
Most people with ME/CFS have trouble with circulation when they stand up. Understand orthostatic intolerance, how to perform a simple standing heart rate test, and what wearables can actually tell you.
Almost none. Sam reads your Apple Health data automatically and asks you one short question a week. There's nothing to log and nothing to maintain.
No. Sam doesn't track symptoms and doesn't make diagnoses. It only reads resting heart rate, HRV, and sleep trends from Apple Health and shows them compared to your personal baseline - your symptoms, and how you interpret them, remain between you and your care team.
The research on this is still ongoing. Many people with ME/CFS find resting heart rate and HRV trends a helpful additional point of reference, but they aren't a proven tool for controlling activity. Sam shows you the data transparently - how much weight you give it is up to you.
No. An Apple Watch can't detect or diagnose ME/CFS - that requires a structured medical evaluation against clinical criteria, such as the Canadian Consensus Criteria. Sam only reads resting heart rate, HRV, and sleep trends from Apple Health and shows them compared to your own baseline - as a starting point for conversation, not a diagnosis.
No - no app can reliably predict the onset of post-exertional malaise (PEM), often called a 'crash,' and that includes Sam. Sam shows you resting heart rate and HRV trends compared to your baseline, but whether and when exertion leads to a crash remains something only you can observe from your own experience.
