ME/CFS Tracker

ME/CFS Tracker is built around the one rule that defines life with myalgic encephalomyelitis: stay inside the energy envelope or pay for it later. Log post-exertional malaise before it becomes a crash, pace your day with real data, and show your doctor what happens when you push past the wall.

Built for people living with ME/CFS, chronic fatigue syndrome, post-viral fatigue, long COVID with ME/CFS features, fibromyalgia overlap, and POTS comorbidity.

ENERGY AND PEM TRACKING
Capture what ME/CFS actually feels like:
• Energy level on a 1 to 10 scale, multiple times per day
• Post-exertional malaise onset, severity, and duration
• Crash logging with trigger activity noted
• Activity type and exertion level before PEM
• Delay between exertion and crash onset
• Recovery time tracking per crash
• Cognitive exertion and brain fog severity
• Physical versus cognitive fatigue split
• Unrefreshing sleep quality
• Custom symptoms you define

PACING AND ENERGY ENVELOPE
The management strategy that actually works:
• Daily energy budget setting
• Activity logging against your envelope
• Rest-to-activity ratio tracking
• Heart rate monitoring for anaerobic threshold pacing
• Step count limits and warnings
• Weekly energy trend to spot overextension
• Boom-and-bust cycle detection

SYMPTOM TRACKING
Log the full ME/CFS symptom picture:
• Orthostatic intolerance and dizziness
• Headaches and neck pain
• Muscle and joint pain
• Sore throat and swollen lymph nodes
• Temperature dysregulation
• Light, sound, and chemical sensitivity
• GI symptoms and food intolerances
• Neurological symptoms and paresthesia

MEDICATION AND SUPPLEMENT LOG
Track everything you try:
• LDN (low-dose naltrexone)
• Abilify at micro doses
• CoQ10, D-ribose, NADH
• B12 injections and iron infusions
• Mestinon for PEM
• Sleep aids and melatonin
• Antivirals and immunomodulators
• Effectiveness ratings per symptom
• Side effect monitoring
• Refill reminders

LIFESTYLE FACTORS
The details that shape your envelope:
• Sleep duration and quality
• Orthostatic load and upright time
• Cognitive load from work, reading, screens
• Emotional stress and social demands
• Weather and barometric pressure
• Hydration and salt intake
• Hormonal cycle phase

INSIGHTS AND REPORTS
Prove what your body already knows:
• PEM frequency, severity, and recovery trends
• Energy envelope adherence over weeks
• Crash trigger correlations with statistical weight
• Activity threshold identification
• Medication and supplement response curves
• Symptom severity heatmaps
• PDF and CSV exports for ME/CFS specialists, immunologists, and primary care

DESIGNED FOR MINIMAL EXERTION
• 30-second quick logging from bed
• Voice-to-text when typing costs too much energy
• Calm, low-stimulation interface
• Health Connect sync for steps, heart rate, and sleep
• Gentle reminders that respect your limits
• Optional biometric lock and offline mode

HEALTH PATHWAYS
• Pacing and energy management guidance
• Sleep hygiene for unrefreshing sleep
• Gentle breathing and relaxation techniques
• Plain-language education on ME/CFS pathophysiology

ME/CFS is not tiredness and it is not depression. ME/CFS Tracker treats it like the neuroimmune condition it is, helping you find the edges of your envelope, avoid the crashes that set recovery back, and hand your specialist the data that validates what you have been living.
