Chronic Fatigue Tracker
Understand your energy patterns. Track fatigue levels, identify triggers, and develop effective pacing strategies to maximize your quality of life with ME/CFS or chronic fatigue.
Why Track Your Energy?
Chronic fatigue conditions are complex and highly individual. What helps one person may harm another. Detailed tracking helps you understand your personal patterns, establish your energy baseline, and make informed decisions about activity and rest.
What to Track for Chronic Fatigue
Energy Levels
Hourly energy ratings, crashes, baseline levels, time-of-day patterns
Sleep Quality
Sleep duration, restorative quality, unrefreshing sleep, napping patterns
Activity & Exertion
Physical activity type and duration, mental exertion, post-exertional symptoms
Physical Symptoms
Muscle pain, joint pain, headaches, sore throat, lymph node tenderness
Cognitive Function
Brain fog, concentration, memory issues, word-finding difficulty
Nutrition & Hydration
Meal timing, protein intake, blood sugar patterns, hydration levels
How Our AI Helps
PEM Pattern Detection
AI tracks your activities and correlates them with symptoms 24-72 hours later to identify your specific PEM triggers and timing patterns.
Energy Envelope Mapping
Identifies your sustainable activity level by analyzing when you crash and when you stay stable, helping you pace more effectively.
Time-of-Day Analysis
Reveals your best and worst times of day for different activities, helping you schedule important tasks during peak energy windows.
Sleep Quality vs. Duration Insights
Separates sleep quantity from quality to help identify what actually contributes to more restorative rest.
Common Chronic Fatigue Patterns
These are frequently reported patterns in ME/CFS. Track to see which apply to you:
Frequently Asked Questions
What is post-exertional malaise (PEM) and how do I track it?
PEM is the hallmark symptom of ME/CFS - a worsening of symptoms 12-72 hours after physical or mental exertion. Track your activities with intensity levels, then log how you feel the next 1-3 days. Our AI identifies your personal PEM triggers and delay patterns.
How do I establish my energy baseline?
Track your energy levels multiple times daily using a consistent scale (1-10) for at least 2 weeks. Note what you were doing before and after each rating. The AI will identify your typical baseline, best/worst times of day, and factors that affect your energy.
Can tracking help with pacing strategies?
Absolutely. By identifying your energy envelope (the activity level you can sustain without triggering PEM), you can develop effective pacing strategies. The tracker helps you recognize early warning signs and stay within your limits.
Why does my sleep not help even when I sleep 10+ hours?
Unrefreshing sleep is a core ME/CFS symptom. Tracking sleep quality separately from duration helps identify if you have sleep stage issues. Note how you feel upon waking, and track any factors that correlate with better or worse sleep quality.
