Your personal operating system for healthy living, whatever your age or fitness level.

You're billed through the Apple App Store or Google Play — the same trusted billing as every app on your phone. One plan at $5.99/month with everything included: nothing held back behind a higher tier. Your first week is free, and you can cancel anytime in your store's subscription settings — cancel during the trial and you pay nothing at all.

It learns how you actually sleep, eat, move, and feel, then shapes each day around it — what's already banked, what's left, and why. It knows what time it is, never invents data, and when you tell it you're feeling low, the plan softens instead of pushing harder. No calorie-shaming, no streak guilt, no "no excuses" voice. Ever.

Day to day, that means keeping you on course across the four things that actually move how you feel — food, water, sleep, and movement. It nudges water in the afternoon when the day has got away from you. It notices that dinner has been late all week and that your sleep followed it. It points out that your best mornings came after the nights you were in bed before eleven. It picks a workout that fits the sleep you actually got, not the one the plan assumed. And it reads the four together, because that is how they behave — a short night shows up in your appetite, and a hard session shows up in the night after it.

The goal is deliberately small: feel better than you did yesterday. Not a target weight, not a perfect week, not a streak to protect. Some days that means going longer. Some days it means water, an earlier night, and nothing else. Miss a day and the coach picks up where you actually are, not where the plan said you would be — because the point is the next good day, not the record.

Your coach: a daily brief plus a real conversation.

You're in control — completely. Every invite shows you exactly what that person will see, element by element — your standard set starts switched on so your circle is useful from day one, and you untick anything you'd rather keep to yourself before the invite goes out, or switch it off later in Manage access, instantly. Chat and celebrations are always part of the Circle. Membership is free for the people you invite.

Every invite shows what that person will see — untick anything before you send.

Snap a photo, scan a barcode, search a catalog of hundreds of foods, or just type it. Calories you log appear beside the active calories your device measured — two honest facts, side by side, never a guilt score.

Everything your device shares, presented honestly — if a metric isn't measured, we never invent it:

Three connections, made once. Your wearable talks to its maker's own app; that app shares into your phone's health platform; HealthyLifeOS reads from there. The key step most people miss is the middle one: open your device maker's app and look in its settings for "Connected apps," "Connected services," or "Health permissions" — that's where you switch on sharing to your phone's health platform.

On iPhone — the platform is Apple Health (the white app with the red heart):

On Android — the platform is Health Connect (built into Android's settings):

Then grant HealthyLifeOS access to Apple Health or Health Connect once (we ask during setup, or in Settings → Connections), and from that moment your sleep, heart data, workouts, and steps flow in automatically — no maker's subscription needed.

Want it walked through, step by step? Our guided setup asks which phone and which wearable you have, then gives you the exact taps — with official videos: Set up your service →

All first-party, all in one place. Each device links its maker's official video and our guided walk with the exact taps:

Apple Watch — Apple's setup video · Apple's pairing guide · our walk →

Galaxy Watch (Android phones only) — Samsung's pairing videos: Galaxy phone / any Android · our walk →

Pixel Watch — Google's setup video · our walk →

Fitbit — Google's setup videos: on iPhone / on Android · our walk →

Garmin — Garmin's pairing video · our walk →

Your phone's health platform — the hop in the middle, explained by its maker: Apple's Health app guide (iPhone) · Google's Health Connect guide (Android).

No wearable? Your phone alone gets you coached from day one — it already counts steps and workouts, and you can log sleep yourself. You will get more out of the app once a device is measuring your nights for you, but nothing here waits on that: see how →

HealthyLifeOS ships real watch apps with workout logging for both worlds: Apple Watch, and Wear OS 3+ (Samsung Galaxy Watch 4 and newer, Google Pixel Watch — round displays included).

Apple Watch — it rides along with the iPhone app:

Galaxy Watch / Pixel Watch (Wear OS) — the watch has its own Play Store:

Didn't appear on your Apple Watch? Most watches install it for you — that's Apple's Automatic App Install, on by default. It's off for some people (it's a common way to save watch storage), and it doesn't apply if you paired the watch after installing HealthyLifeOS on the phone. Two fixes, either works: on your iPhone open the Watch app → My Watch → scroll to Available Apps → tap Install beside HealthyLifeOS. Or turn the automatic behavior back on: Watch app → General → Automatic App Install on — future app updates then reach the wrist on their own. Not in Available Apps at all? Update the iPhone app first; the watch app rides inside it.

Either way, workouts you log on the wrist land in the app instantly — and everything the watch measures overnight flows in through Apple Health or Health Connect as covered above.

No — but you will get noticeably more out of HealthyLifeOS with one. Your phone alone tracks steps, workouts, and the sleep you tell us about, and the coach works from day one. That is a real starting point, not a consolation prize.

Where a wearable changes things is wearing it all day and through the night. Overnight is the part your phone simply cannot see: sleep stages, how broken the night actually was, HRV, resting heart rate, breathing and blood-oxygen trends. Those are the raw material behind readiness, recovery, and a coach that can tell a hard day from a heavy one instead of taking your word for it. Worn through the day, continuous heart rate also makes active minutes, workout intensity, and calorie estimates measured rather than inferred.

So: start with your phone if that is what you have. If you already own a wearable, any device that syncs to Apple Health or Health Connect works automatically — and the more hours you actually wear it, sleep included, the more the coaching has to work with.

No. HealthyLifeOS reads the raw sensor data your device already shares free through Apple Health or Health Connect — not the maker's paid insights. Your hardware, one subscription: ours.

Because Samsung keeps those inside Samsung Health. Energy score, Sleep score, and stress never leave the Samsung Health app — Samsung doesn't share them with Health Connect, so no app outside Samsung Health can display them. That's Samsung's design, not a sync problem on your phone.

Everything Samsung does share flows in automatically: your sleep and its stages, steps, heart rate, workouts, distance, and recovery vitals. Your coach reads those directly — the raw signals behind the scores — and works from how you actually slept and moved, and how you say you feel.

No. Galaxy Watch 4 and newer pair only with Android phones — that's Samsung's rule, not ours — so a Galaxy Watch can't write to Apple Health and HealthyLifeOS on an iPhone can't read from it. The iPhone app says so plainly in Connected devices & apps, so you're never left hunting for a setting that doesn't exist. On an iPhone, Apple Watch, Garmin, Fitbit (via Google Health), Oura, WHOOP, Withings and any other device that shares into Apple Health all work. On an Android phone, your Galaxy Watch is fully supported.

Your health data is protected using industry best practices for security — encrypted in transit and at rest — and is never sold. Period. Sharing happens only through the Care Circle, only with people you invite, only element-by-element with your consent.
