P
Personal, not generic
No health tips from a database. PrimeState uses Pearson correlation — the same statistical method used in clinical research — applied to YOUR data. Every insight is earned from your patterns.
D
Cross-day effects
That brain fog today? Could be something you ate last night. PrimeState learns next-day effects that no other app even looks for — how tonight's dinner affects tomorrow's focus.
C
Gets smarter over time
Every pattern progresses through four confidence levels — from hypothesis to strong. By day 60, you have a comprehensive personal model that keeps learning.

AI Pattern Engine

Patterns you'd never
notice on your own

The AI tracks every food by name, tests cross-day effects, and runs significance testing on every correlation. It might discover that eggs specifically drive your focus — while pasta crashes your energy the next morning.

Supplements are analyzed per-dimension — does magnesium help your focus, energy, clarity, or all three? Every pattern progresses through four confidence levels as your data grows.

Confirmed Patterns Analyzing
Morning walk days +0
Late caffeine (>2pm) -0
Dark chocolate +0
Processed food (48h delay) -0
Morning walks = +2.5 energy same day. 91% confidence. 23 data points.
Caffeine Intelligence

Your metabolism,
not an average

The app tests 11 different half-life values against your actual data to find the one that best explains your energy patterns. Your personalized cutoff time tells you exactly when to stop — down to the minute.

A fast metabolizer might drink coffee until 4pm. A slow one needs to stop by noon. The app figures this out from your data, not a generic estimate.

It gets smarter
the longer you use it

PrimeState builds a model of YOUR brain over time. By day 7, first correlations unlock. By day 30, it's measuring individual supplement effects and suggesting experiments.

By day 60, you have a comprehensive cognitive map — connections no human could spot across hundreds of data points.
