Measure your actual cognitive performance every morning. Not your heart rate. Not your sleep stages. Your brain. Whoop, OURA, and Apple Watch measure heart rate variability and guess how your brain is doing. Your wearable can tell you your nervous system is stressed. It can't tell you your reaction time is 80ms slower than yesterday. BASLN measures the thing itself. 6 RESEARCH-VALIDATED TESTS. 5 MINUTES. - Psychomotor Vigilance (PVT-B): the gold standard fatigue measure, used on the International Space Station - Spatial 2-Back: canonical spatial working memory test, validated across decades of cognitive neuroimaging research - Digit Symbol Substitution (DSST): the single best predictor of complex operational performance - Color-Word Stroop: executive function and inhibitory control - Arithmetic Verification: processing speed under cognitive load - Trail Making B: cognitive flexibility and task switching YOUR PERSONAL BASELINE Your first 5 sessions establish your personal baseline. Every session after that is scored against your own norm. 0-100 scale. No comparison to population averages. Just you vs you. READINESS ZONES 90-100: Locked In 75-89: Good to Go 60-74: Off Day (recovery protocols activate) 0-59: Impaired CUSTOM CORRELATIONS Track what you actually care about. Define your own variables (creatine, cold plunge minutes, supplement stacks) and see how they correlate with your readiness score over time. Binary, continuous, or categorical. RECOVERY PROTOCOLS Score below 75? Get evidence-ranked recovery recommendations: cold exposure, bright light therapy, strategic caffeine timing, high-intensity exercise, nap protocols. Each ranked by time-to-effect and evidence quality. ANALYTICS Track trends across all 6 cognitive domains. See how sleep, caffeine, exercise, and your own custom variables correlate with your scores. Compare your current performance against your original baseline to catch long-term drift. DATA PORTABILITY Export your full history as CSV anytime. Import a BASLN CSV on another device to restore after a reinstall. Every export roundtrips cleanly, no data loss, no lock-in. PRIVACY BASLN collects nothing. Zero. No accounts, no analytics SDKs, no tracking pixels, no telemetry. BASLN has no servers of its own. Your cognitive history syncs across your Apple devices through your private iCloud, end-to-end encrypted. Neither Apple nor BASLN can read it. You can disable iCloud Sync in Settings if you prefer data to live only on the local device. NO WEARABLE. NO ACCOUNT. NO TRACKING. Free to try (10 full sessions). Pro unlocks unlimited sessions, full analytics, and data export. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://basln.app/privacy

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.
