Human Codex: AI Health Agent

Human Codex is your personal health Agent: one app that reads your sleep, recovery, meals, training and labs, and turns them into a plan you can actually follow. YOUR HEALTH AGENT Chat with an Agent that knows your profile, your metrics and your goals. Ask about your sleep, recovery, workouts or meals and it looks up your Apple Health data to answer. It builds your health plan and your training week and adjusts them as you go. It reaches out when it matters and takes action with your confirmation: reschedules sessions, logs what you ask, starts today's run or sends your intervals to your Apple Watch. Give it a name. Voice input supported. DAILY HEALTH SCORE Wake up to one number that reads your sleep, HRV, resting heart rate, activity and recovery, weighted against your own 14-day baseline instead of population averages. It tells you whether to push or recover today. TRAINING, BUILT AROUND HOW YOU MOVE Run, walk or hike from your plan with one tap: your Apple Watch opens the route with your live heart rate and zone, and the session is marked done when you save. Or record with your iPhone alone. Every route goes to Apple Health. Build your strength week by hand from a 110+ exercise catalog, or tell the Agent your goal, days and equipment and it writes the plan. Import your coach's routine from a photo. Progressive overload builds on last week, and a missed day moves to today. One history holds routes, strength sessions and Apple Health workouts; share any activity as a sticker. NUTRITION Snap a photo of a meal, scan a barcode or describe it, and get a macro breakdown in seconds. Log water and caffeine, and set protein, carb and fat targets that fit your plan. FASTING AND METABOLIC TRACKING Start and follow fasting sessions with real-time metabolic phases. Add a glucose or ketone reading and each phase upgrades from estimated to glucose-verified, with your Glucose-Ketone Index (GKI) tracked alongside. VITALS Steps, workouts, heart health and sleep from Apple Health in one dashboard. With Apple Watch, your aerobic capacity (VO2 max) with its 12-week trend and a goal you follow week by week. Turn on a clinical layer for blood pressure, glucose and ketones. APPLE WATCH Your routes open on your wrist with live heart rate and your zone; pause, resume or finish there. Send an interval session to the Workout app, with warm-up, blocks and cool-down. Follow your training day, log sets as you go, and see your score and fasting at a glance. YOUR LABS, IN CONTEXT Type in your labs for free (76 markers across 9 panels) or scan a report as a photo or PDF and the Agent extracts every biomarker. Each panel is read next to what you did in the 90 days before the draw, and when it warrants it, the Agent proposes goal changes until your retest. You confirm each one and can revert any of them. FREE, WITHOUT A SUBSCRIPTION Your Health Score, nutrition and water logging, hand-built training, route recording, fasting, vitals and typed-in labs work end to end at no cost. Pro unlocks the Agent: the conversation, the plans it writes and adjusts, and the lab reads. WORKS WITH YOUR TOOLS - Apple Health: reads your biometrics and workouts, writes nutrition, weight and routes back - Apple Watch app - Home Screen widgets and Siri for your score, fasting and training day - Apple Calendar and Reminders for fasting windows, sessions and reminders YOUR DATA Your health data is stored on your iPhone and in Apple Health.
