Enter today's CFS data above to get 3–5 specific pacing and management actions based on your score right now.

Important: This tool is for general information, not medical advice. Contact your doctor right away if you experience a sudden significant worsening of symptoms, new neurological symptoms (weakness, vision changes, severe headache), high fever, or any symptoms that feel different from your usual CFS pattern. Always consult your healthcare provider before changing medications, supplements, or your CFS treatment plan.

Track your CFS pacing envelope over time with Pro

CFS management depends on understanding your personal energy envelope — the activity level at which you can function without triggering PEM. Pro saves every daily entry, charts your fatigue and PEM patterns, and shows which activities and rest strategies keep you most stable over time.

How To Use

Understand your energy envelope. Track what crashes you. Learn to pace sustainably.

🚀 Getting Started

1

Rate Your Energy

1 = completely bedbound, 10 = pre-illness normal. Be honest about what you can sustain.

2

Log Your Sleep

Hours AND quality matter. Unrefreshed sleep is common in CFS but impacts recovery significantly.

3

Track PEM Events

Post-exertional malaise is the hallmark of CFS. Logging severity helps identify safe activity levels.

4

Read Your Score

Fatigue Management Score combines energy, sleep, PEM, brain fog, activity appropriateness & support into one number (0-100).

🔋 CFS Concepts

Energy Envelope: Your sustainable activity level without triggering PEM. Stay within it to prevent crashes. The envelope can expand with pacing but shrinks with overexertion.

PEM (Post-Exertional Malaise): The hallmark of CFS — disproportionate exhaustion after even minor activity. Can take days/weeks to recover. Tracking helps you spot the line before you cross it.

Boom-Bust Cycle: Good day = do too much = crash. This cycle is the #1 thing holding back CFS recovery. Pacing is staying BELOW your limit on good days to prevent crashes.

Pacing Strategy: The evidence-based treatment for CFS. Not graded exercise — sustainable, consistent activity at 50-70% of perceived capacity. This tracker helps you find and hold that zone.
