Cortex

Most apps guess. Cortex measures. Cortex is a personal attention lab. Every morning, a 60-second reaction test turns your focus into a single score. Then you run real experiments on your own habits โ€” one variable at a time โ€” and Cortex tells you honestly whether anything changed. YOUR MORNING SCORE - A 60-second reaction-time test, taken in your own morning window - Scored against your personal baseline โ€” 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 โ€” 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-day trend charts around your personal noise band (30 and 90 days with Pro) - Optional Apple Health context: sleep, heart-rate variability, resting heart rate and steps alongside your scores - Your data stays on your iPhone โ€” no account, no cloud; CSV export of your last 30 days (full history with Pro) CORTEX PRO The morning test, streaks, and your first experiment are free forever. Cortex Pro unlocks unlimited experiments, correlations, long-range trends, and full history export. - Cortex Pro Annual โ€” US$34.99 per year (auto-renewing) - Cortex Pro Monthly โ€” US$4.99 per month (auto-renewing) - Cortex Pro Lifetime โ€” US$79.99 one-time purchase (not a subscription) Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Your Apple Account is charged for renewal within 24 hours before the current period ends. You can manage or cancel a subscription in your Apple Account settings after purchase. There is no free trial.

Verdict

The call

Bloomkind and Cortex are too close to call on the numbers: across 5 compared parameters โ€” price, ads, in-app purchases and device support among them โ€” neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
