FoggyBrain: Brain Fog Tracker

Why is my head foggy today? If you've ever struggled with brain fog — that frustrating mental haze that makes it hard to focus, think clearly, or feel like yourself — FoggyBrain helps you find the pattern. Log how foggy you feel throughout the day on a simple 0–10 scale, then track the lifestyle factors that might be behind it: sleep, hydration, exercise, sugar, alcohol, and stress. Add your own custom factors too — caffeine, medication, headaches, screen time, anything you suspect. Over time, FoggyBrain reveals the connections you can't see day to day.
