About

FCE (Functional Cognition & Execution) is a baseline-relative functional measurement tool. It compares today’s short-task performance to your own usual range rather than to population averages.

What FCE is

FCE is a short-task instrument designed to detect change in functional execution over time. It measures performance signals such as reaction speed, response control, divided attention, and motor precision.

It does not compare you to a population norm. It compares current performance to your own baseline.

What FCE does

  • Measures short-task functional performance
  • Builds a personal baseline through repeated sessions
  • Compares later checks to that baseline
  • Stores session history locally by default
  • Refuses to score when comparison would be misleading

What FCE does not do

  • It does not diagnose medical, psychiatric, or neurological conditions
  • It does not detect substances or determine their effects
  • It does not explain why performance changed
  • It does not produce automated or binding decisions

One-paragraph overview

FCE is a baseline-relative functional measurement tool that tracks short-task performance over time relative to an individual’s own usual range. It is designed for repeated checks, transparent history, and cautious interpretation, with local-only storage by default and refusal logic that protects against misleading comparisons. FCE is not diagnostic and does not produce automated decisions.

Privacy model

FCE is designed to work locally by default. There are no accounts and no server upload in the default instrument.

  • Local-only storage on this device
  • Manual export only if the user chooses it
  • Transparent session history visible to the user
