Symptom Tracker: Journal

Living with a chronic illness means spending years collecting symptoms in your head, trying to explain months of suffering in a 10-minute doctor's appointment. Symptom Tracker changes that.

Symptom Tracker is the premium chronic illness diary designed for people managing complex, invisible conditions — fibromyalgia, IBS, migraines, lupus, PMDD, POTS, EDS, ME/CFS, endometriosis, arthritis, and more. Log your pain, fatigue, mood, medications, and triggers in seconds. Our analytics find the patterns you've been missing for years.

TRACK EVERY CONDITION, SEPARATELY
Most symptom trackers throw everything into one messy list. Symptom Tracker uses Condition Profiles — isolated workspaces, one per illness. Your fibromyalgia data never mixes with your migraine data. Switch between conditions in one tap. Each profile comes pre-loaded with the symptoms and triggers that matter most for that condition, so you can start logging in under a minute.

Free tier: 1 condition profile.
Premium: unlimited profiles — perfect if you manage multiple chronic illnesses.

SMART TRIGGER ANALYSIS
After 10 days of logging, our on-device analytics identify the patterns you've been missing. We automatically calculate the correlations between your habits and your symptoms so you can clearly see what's driving your flares.

See clear data like:

Fibromyalgia pain increases by 3x on days with poor sleep and high stress.

IBS flares frequently follow a 72-hour pattern after high-sugar meals.

This is the insight your doctor needs — and the one you've been searching for.

DOCTOR-READY PDF REPORTS
Export a clinician-formatted PDF report of any date range — average severity, most common triggers, symptom trends, medication log — all in a format doctors recognize and appreciate. Share it via AirDrop, email, or Messages before your appointment. Arrive prepared. Leave with answers.

LOG IN UNDER 60 SECONDS
Chronic illness brings fatigue and brain fog. The log entry is designed around that reality — large tap targets, symptom chips that remember your usual patterns, auto-fill from Apple Health. Morning, afternoon, evening, and night logging so you can capture how a day actually unfolds, not just a daily average.

BUILT FOR YOUR CONDITIONS
Pre-built profiles with condition-specific symptoms and triggers for:
Fibromyalgia — widespread pain, fatigue, tender points, brain fog, sleep quality
