Circadian Blueprint vs CogniTrack

Your body runs on a 24-hour clock, and light is what sets it. Circadian helps you work *with* that clock instead of against it — wake near sunrise, soak up bright light during the day, and protect your evenings — so you sleep better, feel more energized, and build a rhythm that actually lasts. It runs quietly in the background and adjusts to the sun at your exact location, every single day of the year. No guesswork, no manual updates. WAKE WITH THE SUN Set an alarm relative to sunrise — 20 minutes before, right at sunrise, your choice — and it automatically shifts earlier and later as the seasons change. You wake with natural morning light instead of an arbitrary number on a clock. PROTECT YOUR EVENINGS A gentle reminder fires before sunset (15 minutes by default, adjustable) to put on your blue-light blocking glasses. Cutting evening blue light helps your body wind down naturally and protects your sleep. TRACK YOUR LIGHT Start a Light Session when you step outside and Circadian measures your light exposure, scoring it by brightness, duration, and time of day. Going for a walk? Take a quick reading and pocket your phone — hands-free mode keeps tracking your time. Hit your daily light goal and watch it add up. BUILD THE HABIT A simple daily check-in — "Did you catch the sunrise?" — keeps your streak alive. See your weekly and monthly consistency at a glance, and let small daily wins compound into a real routine. WORKS OFFLINE Sunrise and sunset times are calculated on your device using your location — no internet required after setup. Your data stays on your phone. COMPLETELY FREE Every feature is unlocked for everyone. No subscription, no in-app purchases, no ads, and no third-party tracking.

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.
