## What is Pattern Tracker?

Pattern Tracker helps you notice how symptoms, mood, and possible triggers show up over time without turning your life into a spreadsheet.

Built for privacy-sensitive users who want clarity without subscriptions, Pattern Tracker lets you log what happened, how intense it felt, and what may have been associated with it. Everything works offline and stays on-device.

Use Pattern Tracker to:
- Log symptoms in seconds
- Track mood and severity together
- Tag likely triggers such as sleep, stress, caffeine, meals, or exercise
- Review history in a clear calendar view
- Spot trends and recurring associations over time
- Export clean PDF and CSV summaries when needed

Why Pattern Tracker:
- No account
- No subscription
- Offline first
- Private by default
- Fast, calm, and focused

Pattern Tracker is a self-tracking tool for personal observation only. It does not diagnose, treat, or provide medical advice.
