Training, rebuilt around how you move: • Record your runs, walks and hikes with your iPhone: live map, distance, pace and elevation, with pause and finish on the Lock Screen. Every route is saved to Apple Health. • Training opens on your week: progress, your next session and your latest activity. If a week ends unfinished, pick up the sessions you have left, starting today. • One history for all your activity: routes, strength sessions and Apple Health workouts. Each strength session shows its sets, volume and records, and any activity can be shared as a sticker; routes lead with their shape, or show it over the map or satellite view. • The Agent now reads your recorded runs, walks and hikes to plan your week around them, tells you on your plan when your recovery says push or ease off, and you can see it at work while it builds your health plan or reads your labs. • Ask the Agent about your sleep, recovery, workouts or past meals in your own words. • Fixes and stability improvements.

Meet your Agent: • The Agent now has a face. The mark next to your greeting is alive: it breathes, looks around, blinks, thinks and speaks while it works, and dozes when you've been away. Tap it to open its page, give it a name and review what it knows about you. • It speaks first. Under the greeting it tells you the one thing that matters today and lets you know when your wearable has gone quiet. Tap the bubble to ask about it. • Long-press an Agent message to copy, share or leave a reaction. The Agent also reacts occasionally when you say thanks or finish a workout. • New to the Agent? Discover five useful things you can try, with at most one short tip a day. You can turn tips off. • Your subscription now sits at the top of Account, above your profile. • Fixes and stability improvements.

Share what you finished: • Completed fast, workout, run or week: tap Share on the celebration and get a white sticker with your numbers to place over your own photo or video in Instagram Stories. Copy it, send it straight to Stories, save it, or use the share menu for WhatsApp and more. • Workouts come with three designs to swipe through: total weight lifted in your unit, your plan's weeks and streak, or the lift that beat your previous best. • Edit data hides any number before you share. Nothing leaves the app unless you share it. • Fixes and stability improvements.

A more careful Agent, on iPhone and Apple Watch: • Caffeine is logged only once you've said the size or type of the drink. The Agent asks first — no guessed amounts, and no duplicate entry for a coffee that was already part of your meal. • Glucose readings and labs now say whether they were taken fasting, or that it wasn't confirmed, before the Agent interprets them. • The heart rate and energy your Apple Watch measures inside each workout now reach the Agent and the 90-day read of your labs: average and peak heart rate, calories per session. • One copy/share bar per Agent reply, instead of one under every bubble. • Fixes and stability improvements.

A clearer training week, on iPhone and Apple Watch: • Training is now organized by day, with completed and skipped sessions grouped below your remaining workouts. • Timed exercises show seconds or minutes on both iPhone and Apple Watch. Adjust the duration on your wrist with the Digital Crown. • Cardio keeps the focus on time. Add a load when you need one; the weight field stays out of the way until then. • Paste copied images directly into your chat with the Agent. • Fixes for workout logging, duration targets, and accessibility on Apple Watch.

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.

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.

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.

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.

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.

• Swipe your Health Score — Activity, Heart and Body now live right behind it • Ready-made prompts on the Agent home: daily briefing, sleep, heart trends, doctor-visit prep • Works with your wearable: Garmin, Oura, WHOOP and Fitbit flow in via Apple Health — see Integrations • A cleaner Agent home that fits one screen

We tuned the Agent's engine under the hood: faster, more efficient replies in every conversation. • More reliable logging — fixed a case where a meal or water could be logged twice when confirming your coffee size. • "Remember that…" now always saves to the Agent's memory: tell it your routines once and it keeps them in mind across conversations. • Safer meal corrections ("change it, it was 3 eggs") and minor stability improvements.

Your fasting timer now reads your biology, not just the clock. • Log glucose and ketones during a fast and the metabolic panel syncs with your GKI — the same zones you see in Vitals, one consistent story across the whole app. • The ring, phase timeline, and current phase now follow your verified biomarkers, not just elapsed hours. • Clearer, calmer guidance when a reading falls outside the typical range. • Refinements and cleanup under the hood.

IMPROVED • When the Agent updates one of your goals, a new shortcut in chat takes you straight to the change. • Hydration and caffeine now live in one richer view: trends, quick logging, and your caffeine cutoff in a single place. • Fasting now counts glucose and ketone readings taken up to an hour before you start — and shows your GKI during the fast. • Bug fixes and performance improvements.
