## What is Human Codex?

Human Codex is your personal AI health agent — a single app that brings together your daily Health Score, nutrition, training, fasting, vitals, labs, and intelligent coaching to help you understand your body and take action.

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, not population averages. It tells you whether to push or recover today, and sharpens as it learns your data.

PRECISION NUTRITION TRACKING
Snap a photo of any meal and get instant macro and micronutrient breakdowns. Log water and caffeine. Set personalized protein, carb, and fat targets. Every entry is verified against the USDA database.

PERSONALIZED TRAINING
Build your week by hand from a 110+ exercise catalog — or tell the Agent your goal, your training days, and your equipment, and it writes the plan for you: hypertrophy, strength, powerbuilding, or conditioning & longevity. Import your coach's routine from a photo and it lands in your week, ready to track. Progressive overload builds on what you logged last week, intensity adapts to your recovery — and if life gets in the way, pick back up today and the week slides with you.

AI HEALTH AGENT
Chat with an intelligent agent that knows your profile, metrics, and goals. Ask questions, get meal suggestions, talk through supplementation, request protocol adjustments, or retrieve your Apple Health data — heart rate, HRV, steps, workouts, and more — through natural conversation. Voice input supported.

METABOLIC & FASTING TRACKING
Start, stop, and monitor fasting sessions with real-time metabolic phase tracking. Add a glucose or ketone reading and each phase upgrades from estimated to glucose-verified, with your Glucose-Ketone Index (GKI) tracked alongside. Choose from popular protocols or create your own.

VITALS DASHBOARD
Your everyday signals — steps, workouts, heart health, and sleep from Apple Health — come together in one dashboard with trends and context. Tracking a condition or going deeper? Turn on a clinical layer for blood pressure, glucose, and ketones.

YOUR LABS, IN CONTEXT
Type in your labs free — 76 markers across 9 panels, with your ranges evaluated live as you type — or scan any report as a photo or PDF and the Agent extracts every biomarker. Each panel is read next to what you actually did in the 90 days before the draw — steps, workouts, sleep, HRV — and tells you exactly which days informed it. When a panel warrants it, the Agent proposes moving your goals until your retest; you confirm each change and can revert any of them with a tap. At your next draw, see what each marker did next to what you did — side by side.

FREE, WITHOUT A SUBSCRIPTION
Your Health Score, nutrition and water logging, hand-built training, fasting, vitals, and typed-in labs work end to end at no cost, on your device. Pro unlocks the Agent: the conversation, the plans it writes and adjusts, and the lab reads.

WORKS WITH YOUR TOOLS
- Deep Apple Health integration — reads biometrics, writes nutrition and weight back
- Home Screen widgets and Siri for your score, fasting, and training day
- Notion workspace sync — export your insights and organize your data
- Apple Calendar & Reminders — schedule fasting windows, sessions, and reminders

PRIVACY BY DESIGN
Your core health data stays on your device. AI features use a secure cloud service only when you choose to use them, and only after your explicit consent. You control what data is processed and can revoke access anytime from Settings.

NOT MEDICAL ADVICE
Human Codex is a decision-support tool. All AI-generated content includes clinical disclaimers. Always consult a healthcare professional for medical decisions.

Start free. When you're ready for the Agent, try Pro free for 7 days.

## Version history (last 5 releases)

### 1.4.0 — 2026-09-04

Human Codex on your wrist:

• Your Health Score and today's vitals, one raise away. The watch reads what your iPhone already knows — there's nothing to set up on it.
• Train without your phone: your whole training week lives on the watch. Open any day, log every set, pause when you need to, and let the rest timer tap you when it's time to go again.
• Fasting from the wrist: start or end a fast on the watch and your iPhone stays in sync.
• Your score on your watch face: add a Human Codex complication and it's there every time you check the time.
• Weight now flows both ways with Apple Health, with a one-tap sync in Weight History.

### 1.3.2 — 2026-08-21

A sharper Agent under the hood.

• Your Agent now runs on an upgraded reasoning engine — faster, more capable help with meals, training, fasting, and your labs.
• A clearer subscription screen: exactly what you pay, and when.
• Small fixes and polish.

### 1.3.1 — 2026-08-19

Labs, rebuilt around your real life.

• Type in your labs — free. 76 markers across 9 panels, with your ranges evaluated live as you type. No subscription needed.
• Your labs, read with your last 90 days. The Agent reads each panel next to what you actually did before the draw — steps, workouts, sleep, HRV — and tells you exactly which days informed it.
• The 12-week window. When a panel warrants it, the Agent proposes moving your goals until your retest. You confirm each change — and can revert any of them with a tap.
• The loop closes at your next draw: see what each marker did next to what you did, side by side.

Plus a redesigned subscription screen and fixes across training, dates and language.

### 1.3.0 — 2026-08-14

Training is now yours to shape.

Build your own routine by hand. A catalog of 110+ movements, your own exercises when the catalog falls short, and drag to reorder.

Import the routine you already have. Photograph your coach's sheet or pick a screenshot — it becomes a week you can track, set by set.

The Agent adjusts without rewriting. Swap an exercise or lighten a day; the rest of your program stays exactly as you wrote it.

Your week bends with your life. Add or remove days whenever you want. And when something gets in the way, pick back up today — the rest of the week slides with you, same spacing.

Your history follows the movement, not the spelling. "Bench press" and "press de banca" are one lift now, so your records and starting weights stay whole.

### 1.2.1 — 2026-08-12

Logging food is now instant.

• Food database search — type any food or brand and log it in seconds: millions of products with full macros and micronutrients.
• Exact portions — pick grams or servings and every nutrient rescales instantly. Barcode scans now open on the package serving.
• Your foods, one tap away — recents and frequents live inside the log: repeat a meal in one tap, or adjust today's portion without searching again.
• Under the hood — more accurate mineral and vitamin data from labels, and a more resilient connection to the food database.

Log a full meal in one session: search, portion, done.
