TrackToKnow: Symptom Tracker

Daily health & habit journal

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

Log symptoms from your wrist in seconds. Charts reveal patterns, and a clear report for your doctor is one tap away. Your data stays with you. TrackToKnow is a health and habit journal you fill in with two taps from your watch. The reminder arrives on its own, you answer right in the notification and move on. No hunting for the app, no long forms. YOUR DATA, YOUR FILES • Entries are stored as plain text files in a folder you choose, for example on iCloud Drive. • No account, no third party cloud, no analytics. • Open, back up or analyze your files any time, or feed them to any AI and ask about your own patterns. YOUR OWN QUESTIONS • Track exactly what you need. Scales, yes and no, option picks and numbers. • Three levels of logging. One tap, a quick check or a detailed entry. • Multiple profiles for different areas, for example eyes, migraines or digestion. APPLE WATCH FIRST • Log straight from the notification without opening the app. • Dictate a note from your wrist. • Widgets on iPhone and on the watch. CONTEXT FROM APPLE HEALTH • Heart rate, sleep, breathing and more attach to your entry automatically. • The app only reads from Health, it never writes to it. TRENDS AND A REPORT FOR YOUR DOCTOR • Trends across weeks and months, period comparisons. • A PDF report you can put on your doctor's desk. TrackToKnow Pro unlocks profiles, full history, export, health metrics and backups. The base app is free with no time limit. Subscribe monthly or yearly with a seven day free trial, or make a single purchase that lasts forever. The app provides no medical advice or diagnoses.

What's new in 1.2.0 • Episodes. For a scale or number question you can now track a whole episode, such as a migraine or a cold. Start it on iPhone or Apple Watch, add how it develops and see its length and history. Episodes are also in the doctor report, the backup and the export. • Day completeness. On iPhone or Apple Watch, mark whether you logged the whole day, part of it or only a little. Overview can then compare results from complete days only. Optional evening reminder. • Your own Overview. Use Edit overview to hide and reorder cards, separately for each profile. The Entries per day card pages through months when you view everything. • Profiles can have their own icon, and checklist options can be renamed and reordered. • New Health data page in Settings. It shows what the app reads and fills in data for older entries. Blood pressure from Apple Health now loads correctly. • Tapping a reminder lets you choose Instant, Quick or Detailed. • More reliable reminders on iPhone and Apple Watch, editable notes on entries, language switching without a restart and other fixes.
