ME Ally vs Pacing Guard

ME Ally is a private symptom and pacing journal for ME/CFS and Long COVID. Log daily health, activity, symptoms, crashes, and notes, then review trends and logged crash patterns based on your own history. No account, no ads, no third-party analytics, and no wearable or HealthKit setup required. The Problem ME/CFS and Long COVID can make activity planning difficult. Symptoms may change from day to day, and crashes or post-exertional malaise (PEM) can be hard to understand without a clear record of what happened before and after. The Solution ME Ally turns your daily logs into individualized insights. It estimates your personal energy envelope - activity ranges associated with your logged crash history - and highlights trends, symptom changes, and potential patterns that may be useful for your own review or conversations with your clinician.

Record symptoms and add notes when helpful. • Review: See trends, week-over-week changes, logged crash patterns, and symptom correlations.
