About

Symptom Sense Tracker

Features
Read full description

Symptom Sense Tracker is a private daily check-in for symptoms, mood, routines, and notes. Use a simple 1-10 score to log how you are feeling, then add custom sub-trackers for anything you want to follow over time: mood, pain, fatigue, stiffness, sleep, activity, pacing, medication routines, or your own labels. Add short notes about what happened that day so patterns are easier to review later. The dashboard turns your check-ins into calm, readable trends. Filter by time range, compare custom trackers, review your daily update history, and refresh on-device pattern insights when you want a second look. Designed for privacy: - Your entries are stored locally on your device. - No account is required. - No ads, analytics SDKs, or third-party tracking are included. - Insight generation runs on device when available, with a local pattern analyzer fallback. Symptom Sense Tracker can help you notice associations in your own notes and scores, but it does not diagnose conditions, predict illness, or replace medical care. Discuss important changes with a qualified clinician.
