Tolion Brain Coach

Tolion Health AI

About this app

Turn your health data into brain health intelligence.

Brain Coach connects to Health Connect to read 20 clinically relevant health metrics from your WHOOP, Oura, Fitbit, Garmin and any app that writes to Health Connect — then translates them into a single Brain Health Score backed by neuroscience.

Whether you're optimizing for longevity, managing a genetic risk factor like APOE4, or simply curious what your daily habits are doing to your brain, Brain Coach gives you answers grounded in peer-reviewed science.

BRAIN HEALTH SCORE

Tolion's scoring system weighs 20 metrics — VO2 max, HRV, sleep quality, resting heart rate, heart rate recovery, walking steadiness, active minutes, steps, and more — each weighted by its evidence-based impact on long-term cognitive health. Four category scores (Cardiovascular, Activity, Neurological, Recovery) roll up into one daily Brain Health Score so you always know where you stand.

AI HEALTH INSIGHTS

Ask Tolion AI anything about your health data. Powered by Claude AI, Brain Coach answers questions grounded in your actual metrics — not generic advice. Whether you want to understand what your HRV trend means for brain health, or why sleep quality matters more than sleep quantity, Tolion AI explains it in plain language with scientific references.

PERSONALIZED RECOMMENDATIONS

Brain Coach generates AI-powered recommendations tailored to your specific numbers — not averages. You'll also get 14 evidence-based recommendations with severity ratings and the actual metrics driving each suggestion.

DISCOVER KNOWLEDGE LIBRARY

Browse 100+ topics across exercise, nutrition, supplements, sleep, medications, and cognitive health — each grounded in peer-reviewed research. Topics include evidence grades, key findings, and full reference lists with DOI links. Content adapts to your expertise level, from beginner-friendly summaries to full scientific detail.

PROACTIVE INSIGHTS

Brain Coach watches your data in the background and surfaces insights when they matter — after a workout, following a poor night's sleep, when a trend shifts, or when you hit a milestone. Notifications are optional and fully customizable by category.

APOE4 PROTECTION MODE

If you carry the APOE4 gene variant — a significant genetic risk factor for Alzheimer's disease — Brain Coach offers a dedicated Protection Mode. It reweights your Brain Health Score toward the metrics most protective for APOE4 carriers: VO2 max (18%), sleep quality (14%), and walking speed (8%), all informed by 26 peer-reviewed studies. The AI chat and personalized recommendations also adapt to provide APOE4-specific guidance and scientific context with full citations.

YOUR DATA STAYS YOURS

Brain Coach reads health data locally on your device. Your metrics are never uploaded or shared.
