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 β€’ Track: Log overall health and activity on a 0-10 scale. Record symptoms and add notes when helpful. β€’ Review: See trends, week-over-week changes, logged crash patterns, and symptom correlations. Results show confidence levels based on your data. β€’ Reflect: Use your own history to better understand activity, symptoms, and crashes over time. Core Features β€’ 7-day dashboard with rolling averages and trends. β€’ Pacing insights based on logged patterns. β€’ Energy envelope estimates based on your history. β€’ Logged crash pattern analysis, including pre-crash activity patterns and weekly stats. β€’ Symptom correlations before logged crashes. β€’ Week-over-week symptom changes. β€’ Works offline; optional iCloud sync is off by default and can be enabled during setup or in Settings. β€’ Optional daily reminders. β€’ Face ID/Touch ID lock for security. Premium Upgrade - $4.99 one-time purchase, no subscription β€’ Extended timeframes for Trends: 90 days, 1 year, and all time. β€’ Data export/import: JSON backup and restore. β€’ PDF health reports for clinicians with summaries, charts, and trends. Designed with ME/CFS in mind β€’ Low cognitive load, quick entry, and clear visuals. β€’ Confidence levels when data is limited. β€’ Manual tracking only - no wearable or HealthKit setup required. β€’ Offline-first, with optional sync through your personal iCloud when you choose to enable it. 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. Important Note ME Ally provides personal tracking and analysis only. It is not medical advice and is not intended to diagnose, treat, cure, prevent, or improve any disease or medical condition. Consult a qualified clinician for care decisions.

About

Within

Read full description

Within is a pacing app for people whose energy is limited and unpredictable. Set today's capacity, log what things cost you, keep a reserve and everything stays on your iPhone. Within is built around the energy envelope: an amount you have for today, with a reserve line held back so an ordinary day doesn't have to use everything you have. You say how much you have, tap what you did, and Within shows where the day went. There is nothing to fill, nothing to beat, and nothing that congratulates you for doing more. Everything runs locally. There is no account and no server, Within contains no network code at all, so nothing you log can leave your iPhone unless you export it yourself. HOW IT WORKS Set today's capacity in the morning. Your first feeling is enough, it's an estimate of your day, not a measurement. Tap what you did as the day goes on. Costs are set up once, so logging later takes a tap. Watch the envelope and stay below your reserve line. It's a floor, not a target. In the evening, note how the day went if you want to. Skipping is a complete answer. KEY FEATURES β€’ Today's envelope with a protected reserve line, and a breakdown of where the day went β€’ Activity presets with the cost and length that match your own experience, adjustable any time without rewriting past entries β€’ Upright time and rest tracked separately β€’ Optional symptoms and evening check-in, either can be turned off completely β€’ History with day detail, a month calendar, and week-to-week comparison β€’ Patterns: things that showed up together in your own data, with an attribution window you set for your own delayed onset β€’ Reports for your doctor or care team, PDF and CSV, generated on the device β€’ Crash mode: a quieter screen with no prompts or questions, plus a contact to call, your medications, and communication cards to show someone instead of speaking β€’ Siri and Shortcuts for logging an activity, logging rest, or setting your capacity β€’ Appearance, visual comfort and haptic settings β€’ No streaks, no scores, no rankings. A day with nothing logged is just a day. PRIVACY FIRST β€’ Within has no network code, so your data cannot be sent anywhere β€’ No account, no sign-in, no server β€’ No advertising trackers and no analytics β€’ Everything you log stays on your iPhone β€’ Exports are files made on your device, shared only if you choose to share them IMPORTANT Within is a personal pacing and tracking tool. It is not a medical device and does not diagnose, treat, cure or prevent any condition, including ME/CFS, long COVID, POTS, fibromyalgia or any other illness. Capacity is your own estimate of your day, not a measurement. Patterns Within notices are associations in your own logged data, they are not findings, and they never describe a cause. If you are concerned about your health, please consult a qualified healthcare professional. SUBSCRIPTION Within $2.99 / month, auto-renewing.
