## What is Mu.?

Mu.

Mu. is a daily log for the things that affect how you feel: track mood, symptoms, habits, medications — and let patterns emerge naturally over time. 

Simple. Modern. Free. Private.

—WHAT YOU CAN DO—

*Track Events
Choose what to track: insomnia, anxiety, stress, medication, or create custom events that matter to you. Log as many or as few as you like.

*Log Your Mood
Record how you feel on a scale of 0 to 10.

*Write Notes
Attach a note to any logged event or mood.

*Explore Patterns
View your data with intuitive charts and statistics. Filter by event type and adjust the time period to see what influences your wellbeing.

*Export Your Data
Download your history as a CSV or a detailed PDF report — complete with mood charts, color-coded grids, and event heatmaps. Pick the period and the events you want to include.

*Apple Watch Companion
Log events and your mood directly from your wrist. Data syncs automatically with your iPhone.
