Trace Health is the easiest, most private symptom and mood tracker for iPhone, iPhone Duo and Apple Watch, made for people living with chronic conditions. Log any symptom, your daily mood or your period in one tap, see how they evolve over days, weeks and months, find what triggers or relieves them, and share a clear PDF report with your doctor. Tracking your symptoms is free. Track your symptoms privately, without an account. No sign-up, no personal info ever requested.

Log a symptom with one hand on the cover screen, or open it to see your symptoms and daily activities side by side. Find your triggers and relievers. Log daily activities and habits (food, sleep, stress, exercise, medications, weather) alongside your symptoms, and Trace Health shows you which factors make your symptoms and your mood better or worse.

Loglet turns how you feel into a report your doctor can act on. Log symptoms, blood pressure and medicines in seconds. Loglet lines them up so you and your doctor can see the pattern: when symptoms happen, and how they relate to your medicine times. BUILT FOR REAL LIFE - Log a cramp with one tap, even half asleep at 4am - Big text, big buttons, no jargon, no account - A gentle daily check-in: how are you feeling today? MEDICINES, HANDLED PROPERLY - Split doses (morning and evening) and weekday-only schedules - Check off each dose as you take it - Update a dose or add a new medicine any time it changes BLOOD PRESSURE, DONE RIGHT - Guided sitting then standing readings - See the change on standing at a glance - Every reading timestamped automatically SEE THE PATTERNS - Symptoms by time of day - Symptoms in the hours after your morning dose - Blood pressure drops on standing, flagged clearly THE DOCTOR REPORT One tap creates a clean PDF: your medicines and schedule, symptom counts and severity, timing patterns, blood pressure trends and adherence. Print it, email it, or hand over your phone. PRIVATE BY DESIGN Everything stays on your phone. No account, no cloud, no ads, no tracking. Sharing a report is always your choice. Loglet is an informational logging tool, not a medical device. It never diagnoses and never gives dosing advice. Always consult your doctor about your health and medicines.

Verdict
The clearest difference is in-app purchases: Loglet at none against Trace Health's 3. Loglet also leads on iOS requirement (15.0 vs 18.0). Trace Health's advantage is update cadence (every 2 days vs every 10 days). On price, ads and device support there is nothing between them.
