## What is Symptom Tracker & Health Diary?

PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase.

Each entry captures the symptom name, a 1-to-10 severity rating, how many hours it lasted, and what may have caused it. A chart view shows severity trends over time so you can spot patterns before your next doctor visit. Notes let you add extra context to any entry. All data is stored locally via SwiftData — no account, no sharing, completely private.
