ME Ally: Symptom Tracker

Log symptoms quickly. Review trends, logged crash patterns, and activity range estimates for ME/CFS or Long COVID. No account, no ads, no subscription.

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.

How It Works • Track: Log overall health and activity on a 0-10 scale. Record symptoms and add notes when helpful. • Review: See trends, week-over-week changes, logged crash patterns, and symptom correlations. Results show confidence levels based on your data. • Reflect: Use your own history to better understand activity, symptoms, and crashes over time.

Core Features • 7-day dashboard with rolling averages and trends. • Pacing insights based on logged patterns. • Energy envelope estimates based on your history. • Logged crash pattern analysis, including pre-crash activity patterns and weekly stats. • Symptom correlations before logged crashes. • Week-over-week symptom changes. • Works offline; optional iCloud sync is off by default and can be enabled during setup or in Settings. • Optional daily reminders. • Face ID/Touch ID lock for security.

Premium Upgrade - $4.99 one-time purchase, no subscription • Extended timeframes for Trends: 90 days, 1 year, and all time. • Data export/import: JSON backup and restore. • PDF health reports for clinicians with summaries, charts, and trends.

Privacy First Your data belongs to you. ME Ally stores app health data locally by default. If you choose to enable iCloud Sync, app data syncs through your own iCloud account using Apple's CloudKit service. We do not receive your health data, and we do not sell or share it. No account, no ads, no third-party app analytics, no tracking, and no HealthKit or wearable setup required.

Who It’s For People living with ME/CFS, Long COVID, POTS, or other conditions where overexertion may be associated with symptom flare-ups or PEM. ME Ally helps you track what happens and review your patterns over time.
