Most apps guess. Cortex measures. A 60-second reaction time test every morning gives you a focus score against your own baseline. Then one-habit experiments show whether sleep, caffeine or a new routine actually changed it: real effect, no effect, or inconclusive. YOUR MORNING SCORE - A 60-second reaction-time test, taken in your own morning window - Scored against your personal baseline — never someone else's average - Streaks, shields, and ranks that reward showing up REAL EXPERIMENTS - Change one variable: caffeine cutoff, phone-free first hour, shorts curfew, cold finish, and more - Cortex compares your baseline days against intervention days - Verdicts are graded by evidence strength — A, B, or C HONEST BY DESIGN - If the result is noise, Cortex says so: "no meaningful effect" is a real answer - No made-up insights, no dressed-up randomness - Correlations are labeled as hints, not verdicts TRENDS AND CONTEXT - 14-, 30- and 90-day trend charts around your personal noise band - Optional Apple Health context: sleep, heart-rate variability, resting heart rate and steps alongside your scores - Your data stays on your iPhone — no account, no cloud; full CSV export any time SUBSCRIPTION REQUIRED Cortex is a paid app: a subscription (or the one-time Lifetime purchase) is required to use it — there is no free plan.
