Stop guessing which supplements actually work. Cortex builds your personalized protocol, tracks how you feel, and tells you what's moving the needle and what to cut. Your AI coach. Your data. Your optimized stack. Tell Cortex your goals, sensitivities, and current regimen, and the AI coach builds a personalized stack you can actually follow, then helps you adjust it over time. Every compound is shown with its evidence tier, and recommendations are backed by citations to the research behind them, so you can see why something is suggested and weigh it with your own clinician. A Cortex membership is required to access your personalized stack and the AI coach. Membership includes: - A personalized stack built around your goals, sensitivities, and current regimen - An AI research coach for stack questions and optimization — educational information, not medical advice - Daily tracking with correlation analysis, so you can see what's actually working - Compound profiles with evidence tiers and citations to peer-reviewed and institutional sources (PubMed / NIH) - Research summaries on potential compound interactions - Cycling schedules and washout tracking Cortex requires an auto-renewing subscription to access your personalized stack and the AI coach.

Verdict
The clearest difference is update cadence: Cortex at every 11 days against BioTrace's every 6 months. BioTrace's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.
