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:

Post-exertional malaise (PEM)(Activity)
Unrefreshing sleep despite long hours(Sleep)
Brain fog after mental exertion(Cognitive)
Afternoon energy crashes(Energy)
Orthostatic intolerance(Cardiovascular)
Boom-bust activity cycles(Activity)
Blood sugar fluctuations(Nutrition)
Sensitivity to light/sound/stimuli(Sensory)
Symptom flares with stress(Stress)
Temperature regulation issues(Autonomic)
Delayed symptom onset (24-72 hrs)(PEM)
Seasonal or weather-related patterns(Environment)

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.
