Say how you feel. It's logged. Symptom Log is a symptom diary for bad days. Hold the button, say what's going on — "headache behind my left eye since lunch, took ibuprofen" — and let go. Your words land on a timeline, transcribed on your phone. No forms. No sliders. No chatbot. ONE TAP A DAY Pick the color of your day: clear, fair, hazy, cloudy or stormy. Days logged keep adding up, even when you skip a few. BAD DAYS, IN YOUR OWN WORDS • Hold and talk whenever something changes • Every note lands on one timeline, with the time • What you tried — meds, rest, ice, a dark room — is kept apart • Name your own symptoms in your own words ONE PAGE FOR YOUR DOCTOR Before an appointment, get the last 30 days on one page: what came up most, your longest stretch, what you tried and the questions you want to ask. Save it as a PDF, print it or email it. YOUR YEAR, IN COLOR Every day becomes one square. Share your year in color or a 100-days card: just colors — no words, no dates, nothing private. PRIVATE BY DESIGN • Your voice is transcribed on your phone and never stored • Your notes stay on your device • No ads, and no health data shared with advertisers Symptom Log is a personal journal. It does not diagnose, treat or give medical advice. Talk to a qualified health professional about your health. SYMPTOM LOG PRO Unlimited voice notes, the one-page PDF, monthly and milestone cards, and air pressure next to your timeline. The free plan keeps daily colors and 3 voice notes a week. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

Verdict

The call

The clearest difference is ads: Symptom Tracker at none against SymptomLog's shown. SymptomLog's advantage is update cadence (every 2 days vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
