Brain fog tracker
There's no app for brain fog — until now. Millions deal with post-COVID fog, diet-driven haze, and afternoon crashes with zero way to track it. OutLast is the brain fog tracker that connects what you eat, how you sleep, and how sharp you feel — so you can finally find the patterns behind the fog.

The problem
Some mornings you're razor-sharp. Others you can't remember why you walked into the room — and you have no idea what changed
You suspect it's food, sleep, or stress — but without tracking, you can't prove which trigger is doing the damage
Generic health apps don't have a "brain fog" category. Symptom trackers are built for chronic illness, not cognitive clarity
OutLast makes it simple: rate your mental clarity, log what you ate and how you slept, and let the patterns reveal your personal fog triggers
How it works
Log how sharp or foggy you feel — morning, afternoon, evening. It takes 5 seconds and builds a cognitive clarity timeline you can actually learn from.
Track what you eat, how long you slept, caffeine intake, and anything else that might affect your brain. The more you log, the clearer the picture becomes.
After a week or two, your data tells the story. See which meals, sleep patterns, or habits correlate with fog — and which ones give you your sharpest days.
What you get
Rate how clear or foggy you feel at any point in the day. Over time, you'll see exactly when your brain is sharpest and when the fog rolls in.
Is it the pasta at lunch? Poor sleep? Skipping coffee? OutLast connects your clarity ratings to everything else you log — revealing the triggers hiding in plain sight.
Log what you eat and tag your post-meal mental state. Spot which foods leave you sharp and which ones send you into a 2 PM haze.
Track your sleep and see how it maps to next-day brain fog. Find your personal sleep threshold — the hours you need for a clear-headed day.
The science
What people say
“I’d been foggy every afternoon for months. After two weeks of tracking with OutLast, the pattern was obvious — high-carb lunches were destroying my focus. Switched to protein-heavy meals and the fog is gone.”
“Post-COVID brain fog was ruining my work. My doctor said to ‘keep a journal’ but that never stuck. OutLast made it easy to log how I felt and what I did each day. Now I know exactly what helps and what makes it worse.”
“I thought my brain fog was random until I started tracking sleep alongside it. Turns out anything under 7 hours and I’m useless the next day. Now I protect my sleep like it’s my job.”
