Welltory vs Samsung Health: what each shows on a Galaxy Watch

Short answer

Samsung Health is the app your Galaxy Watch is built around: it tracks sleep, stress, heart rate, blood oxygen and, in the 2026 layout, an overnight Vitals check, and adds Energy Score and Bedtime Guidance (1, 4). Welltory is a separate app that runs on the same watch and takes heart rate variability (HRV) readings you can see as a number, then turns them into daily Health, Battery and Stress scores (11, 13).

The short rule: you don't have to choose. Samsung Health stays your watch's home base. Welltory is an add-on for people who want to see their HRV readings, tag what happened that day and read stress and energy against their own history.

If you've opened Samsung Health looking for your HRV in milliseconds and couldn't find it, you're not imagining it. The Samsung pages we checked describe HRV as an input to stress and Vitals, not as an on-demand number you can open (5, 4).

Note: this article is for general education and is not medical advice. Neither app's wellness features are designed to diagnose a condition. Samsung features were checked on Samsung's official pages in November 2026 and Welltory features against the Welltory Help Center on November 8, 2026; both can change with updates and by country. This guide is published by Welltory, which makes one of the apps mentioned. Samsung, Galaxy and Samsung Health are trademarks of Samsung Electronics Co., Ltd.

Welltory vs Samsung Health at a glance

What Samsung Health already gives you

Start here, because most of what you need from a Galaxy Watch is already in Samsung Health.

Sleep. The watch tracks sleep stages and gives a sleep score. Bedtime Guidance, introduced with One UI 8 Watch, suggests a bedtime based on three days of sleep and your sleep pressure and circadian rhythm (2).

Stress. Samsung's US support page says the watch "uses heart rate variability (HRV) to estimate stress levels" (5). You see a stress level, not the HRV number behind it.

Vitals. In the 2026 Samsung Health update, overnight HRV is analyzed together with heart rate, breathing rate, skin temperature and blood oxygen in a section called Vitals, which flags changes from your own baseline (4). Samsung says new features roll out first on newer watches.

Energy Score. A daily number built from your sleep, activity and heart data, meant to summarize how ready you are for the day (1, 3).

Newer wellness features. Galaxy Watch8 added Vascular Load (load on blood vessels during sleep), Antioxidant Index (a quick thumb test for skin carotenoids) and Running Coach (1, 2).

Regulated heart features. In the US, Samsung offers an ECG app, irregular heart rhythm notifications and an FDA-authorized sleep apnea feature, and began a phased rollout of cuff-calibrated blood pressure on March 31, 2026 (3, 6). Our guide to blood pressure on Galaxy Watch covers the calibration steps.

Welltory doesn't replace any of these features and doesn't offer ECG, rhythm alerts or sleep apnea detection.

What Welltory adds on a Galaxy Watch

Welltory installs on the watch itself and works next to Samsung Health (11).

HRV readings you can see. You can start a reading on the watch by pressing the red button in the Welltory watch app, or let the watch take automatic readings during the day. Automatic readings happen only when you're calm, so not while you sleep, move or exercise. Results appear in your Welltory feed, and with Welltory 4.6.5 or newer on Wear OS, HRV insights also show on the watch (11).

Daily scores from those readings. Welltory turns HRV into Health, Battery and Stress indicators. The free version keeps the daily indicators and one HRV reading a day with five core indexes; Premium gives a full analysis with 21 metrics and unlimited readings (13).

Context next to the number. Premium on Android adds Sleep Analysis, Sleep Flow, a Workout Report, a Journal, an Activity Widget for Samsung Watch users and blood pressure analysis with five indices when you log readings from a cuff (14).

Your Samsung Health data in the same place. You can connect Samsung Health in Welltory so steps and other available data appear in your charts. Samsung doesn't open every data type by default; you can grant more in Samsung Health under Settings → Apps → Welltory (12).

A spot reading without the watch. If the watch isn't on your wrist, you can take a short reading with the phone camera and flash on supported phones. It's a deliberate spot measurement, not continuous monitoring (15).

HRV: a background trend vs a reading you take

This is the core difference between the two apps, so it's worth slowing down.

Samsung Health reads HRV quietly. The watch records it during sleep and rest and uses it inside other features: stress estimates during the day and the Vitals check at night (4, 5). You don't have to do anything, and you mostly hear from it when something changes.

Welltory asks you to take a reading. The most useful habit is one reading at the same time each morning, sitting still, before coffee. Automatic readings add more points through the day (11).

Why the two can disagree. An overnight value and a morning reading taken sitting up measure different moments. HRV shifts with position, breathing, time of day and the length of the recording window, and it differs a lot between people of the same age (8). So a calm Vitals screen and a lower Welltory reading on the same morning don't mean one app is broken. Compare each number with its own history, in the same app. Our guide to what a good HRV range is explains how to read your own.

Which view suits you. If you want to be left alone unless something changes, Samsung's background approach fits. If you want to see the number every morning and connect it to yesterday, a reading you take fits better. Many people use both.

If you mainly want to find HRV inside Samsung Health, our page on HRV with Galaxy Watch walks through where it shows up.

Stress, energy and readiness: Energy Score vs Health, Battery and Stress

Both apps give you a quick morning answer to "how much do I have today?" They build it differently.

Energy Score combines sleep, activity and heart data into one daily number (3). It's convenient, and it updates without any action from you.

Welltory's Health, Battery and Stress come from your HRV readings. Battery is about energy for the day, Stress about load on your nervous system, and Health about the overall picture (13).

When they disagree. A good Energy Score and a low Battery on the same day usually means the two apps weighed different inputs, such as last night's sleep versus this morning's reading. Look at the inputs before you change your plans: sleep length, resting heart rate and how you actually feel. If you want a broader look at how brands build these scores, see readiness score apps compared.

Does it need a Samsung phone or an iPhone?

Galaxy Watch and Samsung Health. Galaxy Watch pairs with Android phones, but Samsung lists the ECG app, the sleep apnea feature, Energy Score insights and Bedtime Sync among features not available with non-Samsung Android phones (3). Blood pressure also needs a Samsung Galaxy phone on Android 12 or later (6). Galaxy Watch doesn't work with iPhone.

Welltory. Welltory has apps for iPhone and Android. On a Galaxy Watch, it needs the watch synced to your phone through the Galaxy Wearable app (11). On iPhone, Welltory takes HRV readings with an Apple Watch, a compatible chest strap or the camera instead (10).

Other Samsung devices. Welltory uses Galaxy Ring and Galaxy Fit 2 and 3 for activity tracking only, not for HRV readings (10).

What it costs

Samsung Health. On the Samsung pages we checked in November 2026, health features come with the watch and no subscription is mentioned. Some features depend on your phone and country, as above.

Welltory. New accounts start with a three-day trial (72 hours from sign-up) of the full app. After that, a free version stays available: daily indicators, one HRV reading a day with five core indexes, blood pressure analysis with three indexes, sleep duration, breathing exercises and tests. On the free version, data older than 30 days is deleted, so export it first if you want to keep it (13). On a Galaxy Watch, free accounts get one manual and one automatic watch reading a day; Premium removes the limit (11).

Welltory's plans page listed Premium at $99 a year, which "auto-renews annually at the regular price unless canceled," or $599 as a one-time lifetime payment, on November 8, 2026 (18). App Store and Google Play prices can differ. You cancel where you paid: in Google Play, the App Store or the Welltory web app, and access continues until the paid period ends (19). Our page on whether Welltory is free goes through the free version in detail.

Using both together: a setup that works

If you already wear a Galaxy Watch, here's a simple way to run both apps without double work.

1. Keep Samsung Health as your watch's main app. Leave sleep tracking, stress and any regulated features you use there.

2. Sync the watch in Galaxy Wearable and check that it shows as connected (11).

3. Install Welltory on the watch. In the phone app, go to Menu → Settings → Primary device, tap "Install Welltory on my watch," pick your model and install it from Google Play on the watch (11).

4. Grant the watch permissions, including background HRV, and choose "All the time" if you want automatic readings (11).

5. Connect Samsung Health in Welltory and turn on all the sliders so steps and other data appear in your charts (12).

6. Take one manual reading each morning at the same time, sitting still. Do this for two weeks before you read anything into the numbers.

7. Tag your days. Late caffeine, alcohol, a hard workout, a bad night, a deadline. After two weeks, these notes are what explain the numbers.

Which one fits you: five situations

None of this is a ranking. It's which tool fits which job.

"I just want my watch to work and tell me if something's off." Samsung Health is enough. Vitals and stress run in the background.

"I want to see my HRV as a number every morning." Add Welltory. Samsung's pages don't describe an on-demand HRV value in milliseconds; Welltory shows your readings in the feed (11).

"I need ECG, rhythm notifications or blood pressure." Those are Samsung Health Monitor features with phone, age and country requirements (3, 6). Welltory doesn't offer them.

"My Android phone isn't a Samsung." Samsung Health still works, but several insights and the regulated features need a Galaxy phone (3). Welltory's watch readings need the watch synced through Galaxy Wearable.

"I don't wear a watch at night, or I'm moving to an iPhone." Welltory can work from morning camera readings on supported phones, or with an Apple Watch on iPhone (10, 15).

Common mistakes when comparing Welltory and Samsung Health

• Comparing a stress level with an HRV number. Samsung shows a stress estimate; Welltory shows readings and scores built from them. They aren't the same scale.

• Comparing overnight data with a morning reading. Different moments, different positions, different values (8).

• Judging after three days. Both apps compare you with your own history. Give it two weeks of steady readings.

• Measuring right after coffee, a workout or a stressful call. Your reading will reflect that moment. Pick a calm, repeatable time.

• Expecting every Samsung feature on any Android phone. Check the list of Galaxy-phone-only features before you buy (3).

• Expecting Welltory on a Tizen watch. Welltory's watch app needs Wear OS, Galaxy Watch4 or later (11).

Living with Samsung Health and Welltory: the questions people ask next

Is there a Samsung Health alternative that shows HRV?

Samsung Health uses HRV inside stress and Vitals. If you want to see readings as numbers, apps that measure HRV through the watch can show them. Welltory does this on Galaxy Watch4 and later on Wear OS (11). Most people keep Samsung Health and add such an app rather than replace it.

Is there a Samsung Health Premium?

On the Samsung pages we checked in November 2026, we found no paid tier for Samsung Health. If Samsung adds one, check its official page for what it includes and how renewal works.

Will Welltory drain my Galaxy Watch battery?

Welltory's Help Center doesn't give a battery figure. You can set how often automatic readings happen in the Samsung Watch section of the Welltory menu; the setting is a minimum gap between readings, not exact times (11).

Why is my Samsung stress high but my Welltory stress normal?

They're measured at different moments and calculated differently. A single high stress reading after climbing stairs or a tense call reflects that moment. Look at the pattern over a week in each app.

Does Welltory work with Galaxy Ring?

Yes, for activity data. Welltory lists Galaxy Ring for activity tracking, not for HRV readings (10).

Before you blame yourself

When an app says your stress is high or your energy is low, it's easy to hear "you're handling life badly." Before you go there, look at your data.

The feeling: "My stress is always high and I don't know why."

The cause you can often see: short sleep three nights in a row, coffee after lunch, alcohol, a hard training block, a cold coming on, or a week of late screens. These lower HRV and raise resting heart rate, and both apps will pick them up in their own way.

One lever for one to two weeks: pick the single thing that shows up most in your tags and change only that, say a bedtime before 11 p.m. or no caffeine after noon. Then compare your morning readings with the two weeks before.

If nothing moves after a real change, that's useful too. It's a reason to look wider, at sleep problems, medications, thyroid or ongoing stress, not a verdict on your willpower.

When to see a doctor

Neither app can rule anything out. See a doctor if:

• Samsung's irregular rhythm notification fires, especially more than once.

• Your resting heart rate stays well above your usual level for more than a week with no clear reason.

• You feel faint, dizzy or short of breath, or your heart races at rest.

• You snore loudly, gasp at night or feel sleepy every day despite enough time in bed.

Call 911 for possible heart attack signs: chest discomfort, discomfort in other areas of the upper body, shortness of breath, a cold sweat, nausea or lightheadedness (9). Don't wait for a watch to confirm anything.

How to bring this up with your doctor

What to ask for, by name. After a rhythm alert: "Can we confirm this with a 12-lead ECG?" After weeks of poor sleep or loud snoring: "Should I have a sleep study?"

What to bring. A saved ECG from Samsung Health Monitor if you took one, the dates of any alerts, and two to four weeks of resting heart rate, sleep and HRV trends. Welltory's web app exports your charts as a CSV file (17).

What to say if you're brushed off. "I know a watch isn't a diagnosis. I'm asking whether these symptoms and this pattern are worth one proper test."

How Welltory helps — and what it cannot do

The limits first. Welltory is a general wellness product, not a medical device. It doesn't diagnose heart rhythm problems, sleep apnea or any other condition, and it doesn't replace Samsung's ECG, alerts or a visit to your doctor.

HRV readings on your Galaxy Watch. Welltory supports Galaxy Watch4 and later on Wear OS, including Wear OS 6. Take a reading with the red button or let the watch read automatically when you're calm. Free accounts get one manual and one automatic reading a day; Premium, a paid subscription that renews automatically until you cancel, removes the limit (11).

Sleep on Android. In Premium, Sleep Analysis can use sleep data from Health Connect to build a Sleep Score (16).

A camera reading when the watch is charging. On phones where the camera and flash sit close together, you can take a fingertip spot reading. It doesn't work on Google Pixel phones, isn't an ECG and is unreliable with arrhythmias (15).

A record you can take with you. From the web app: Dashboard → choose a chart → pick the time range → Export (17).

The annual plan renews automatically until you cancel; the lifetime plan is a one-time payment. The exact discount appears on the payment screen before you enter card details.

How we made it

We based this comparison on Samsung's announcements for Galaxy Watch8 and Galaxy Watch9, One UI 8 Watch and the 2026 Samsung Health update, Samsung's US Galaxy Watch8 page and stress support page, Samsung's US blood pressure announcement, a review of HRV metrics and the American Heart Association's warning signs page. Samsung features were checked on official Samsung pages in November 2026. Search questions came from what people in the United States most often ask about Samsung Health and Welltory. For the product section, we checked every function against the Welltory Help Center on November 8, 2026.
