Find what changes your focus and brain fog

Normal helps connect mental clarity to sleep, food, caffeine, pressure, fasting, movement, and blood sugar patterns.

When this helps

Use this when your focus varies dramatically by day, brain fog hits at predictable times, or coffee and sugar help briefly then make things worse.

Normal compares your sharp days with your foggy days until the difference becomes visible.

What Normal looks for

It looks for patterns across sleep, meals, caffeine, fasting, movement, stress, and time pressure.

Example focus pattern

brain fog is awful today
when did it start?
after lunch.
same as yesterday.
both days had a sweet drink and low sleep.
your clearest afternoons this month had more protein at lunch and no sugar spike.
i thought i was just bad at focusing
your focus is responding to conditions.
let's find the ones that work.

What this means

Focus is not only discipline.

For many people, brain fog follows sleep, food, caffeine, pressure, or timing. Normal finds the conditions where your mind clears up.
