## What is defog?

Some days your mind is sharp and clear. Other days it feels slow, heavy, and foggy, and you can't figure out why. 

Defog helps you connect the dots.

Track your clarity alongside the things that shape it, and turn your daily check-ins into personal insights, reports, and simple experiments, so you can see what actually helps.

TRACK WHAT SHAPES YOUR CLARITY
Log daily clarity, sleep, stress, meals, caffeine, water, exercise, steps, meditation, and more in a quick check-in. 
The more you log, the clearer your patterns become.

SPOT POSSIBLE FOOD TRIGGERS
Food can change how clear your mind feels. Log a meal, then do a quick post-meal "fog check" to rate your clarity afterward, and start noticing food/fog patterns over time.

UNLOCK PERSONAL INSIGHTS
Defog turns your check-ins and logs into AI-generated reports that surface what keeps repeating across your foggy days, your clearer days, and everything in between:

- Early Insights
- Weekly Insight Reports
- Monthly Pattern Reports

TRY SIMPLE EXPERIMENTS
A pattern is only useful if you can act on it. Defog turns yours into simple, one-thing-at-a-time experiments so you can test what actually moves your clarity:

- Move caffeine earlier in the day
- Skip a possible trigger food
- Take a short walk after meals
- Try a different bedtime routine
- Compare your clarity before and after a small change

CLARITY RESET
When the fog becomes too much. Clarity Reset is a short, guided breathing exercise to help you slow down and steady your mind in overloaded moments.

JOURNAL YOUR DAYS
Capture notes, symptoms, and observations worth remembering. Over time, your journal helps Defog build a clearer picture of what may be affecting your clarity.
