CogniTrack vs Cortex

CogniTrack Pro turns your iPhone into a private lab for your mind, recovery and daily health routines. Track attention, memory, reaction speed, HRV, activity, sleep and optional glucose context in one calm app. Follow short morning and evening routines, run research-inspired cognitive exercises, and see your personal trends over time — without accounts, ads or cloud upload. WHY I BUILT COGNITRACK PRO I am a PhD bioinformatician and have worked with artificial intelligence and data-driven analysis for more than 20 years. I am also fascinated by longevity, healthy habits and the question of how small daily routines compound over time. My belief is simple: long-term progress starts with consistency, good measurement and clear feedback. CogniTrack Pro was created to bring that approach to everyday cognitive and wellness tracking — privately, practically and without unnecessary complexity. WHAT YOU CAN DO • Follow guided morning and evening routines for focus, reflection and recovery • Train with classic cognitive paradigms such as N-back, Stroop, Go/No-Go, digit span, symbol-digit and reaction time • Build a Cognitive Index and see how your results change over time • Connect Apple Health to review HRV, resting heart rate, sleep, activity and workout context • Add optional glucose readings and estimate long-term glucose trends • Explore correlations between routine, health signals, phone use and cognitive performance • Get practical recommendations based on your own patterns • Use the app in English, German, Spanish and French PRIVATE BY DESIGN Your data is yours. CogniTrack Pro works fully offline and does not use tracking, ads or analytics SDKs. No account is required. Nothing leaves your phone unless you export it or intentionally enable your own self-hosted sync. IMPORTANT CogniTrack Pro is a wellness and education app. It is not a medical device and does not diagnose, treat, cure or prevent any disease. Scores, ranges and trends are estimates from your own data and are not a substitute for professional medical advice.

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.
