How to set up Welltory on Android: Health Connect, watches and your first reading

Short answer

To set up Welltory on Android, install it on a phone running Android 9 or higher, sign in, connect one data hub — Health Connect or Samsung Health — and then either add a Samsung Galaxy Watch or take your first reading with your phone camera (1). On Android, only Samsung watches running Wear OS (Galaxy Watch 4 and newer) can take heart rate variability (HRV) measurements inside Welltory; Garmin, Fitbit, Pixel Watch, Oura and most other devices send activity and sleep, not HRV (1, 2, 3). The camera doesn't work on Google Pixel phones (4).

If setup feels fiddly, it's not your fault: on Android, health data passes through several apps and permission screens before it reaches any app, including ours. This guide walks through each one.

Note: this article is for general education and is not medical advice. Welltory is a general wellness product, not a medical device: it doesn't diagnose or treat any condition and is not an ECG. Measurements may not be accurate if you're under 18 or pregnant, and phone-camera readings are unreliable with arrhythmias (1, 4). Chest discomfort, shortness of breath or a cold sweat can be signs of a heart attack: call 911 (12). This guide is published by Welltory and describes our own app; every function was checked against the Welltory Help Center on November 8, 2026.

Explore your data

What you need before you start

• An Android phone with Android 9 or higher (1).

• A Google account, email address or Facebook account to sign up (1).

• Health Connect or Samsung Health on the phone. These are the hubs ("aggregators") that collect data from your watch and other apps and pass it to Welltory (1, 5). Our explainer on the Health Connect app covers what it is and how it handles your data.

• Optional: a Samsung Galaxy Watch 4 or newer running Wear OS, if you want HRV measurements from the wrist (2).

• Optional: a compatible chest strap such as Polar H10, Garmin HRM-Pro or Wahoo TICKR, if your phone camera doesn't work for readings (3).

One account, one platform. Welltory recommends using it on only one platform, Android or iOS. Mixing accounts can make reports inaccurate (1).

Step 1: install Welltory and sign up

1. Install Welltory from Google Play.

2. Sign up with your Google account, email or Facebook (1).

3. Go through onboarding. At the last step you'll be offered a Premium subscription. If you want to try the free version first, close the offer with the cross in the top-left corner on Android (1).

4. Note when your trial starts. New users get a three-day (72-hour) trial of Premium features (11). Check the exact end time in the app.

The Menu on Android opens from your profile picture. That's where you'll find Apps, Settings, Galaxy Watch and Tests (1).

Step 2: connect Health Connect or Samsung Health

Pick one hub. If you have a Samsung phone and a Galaxy Watch, Samsung Health is one option. If you use Fitbit, Garmin, Oura, Polar, Coros or Withings, Health Connect is the usual route (1, 7).

To connect Health Connect:

1. Install Health Connect on your phone if it isn't there already (7).

2. In Welltory, open Menu → Apps.

3. Scroll to Health Connect and tap Connect.

4. When Health Connect asks, tap Allow All so it can send data to Welltory (7).

5. Open your source app — for example, your watch's companion app — and turn on data transfer to Health Connect in its settings.

6. In Health Connect → App permissions, check which apps can read and write your data (7).

You can also choose your hub under Menu → Settings → Apps to get data from (1).

What arrives through Health Connect. Welltory says it receives all data types it's able to process from Health Connect (5). Some devices need a third-party app to reach Health Connect first; the Help Center has sync guides for Coros, Fitbit, Garmin, Oura, Polar and Withings (7).

If you used Google Fit. Google stopped supporting direct app connections through Google Fit on June 30, 2025. To keep data flowing, connect Google Fit to Health Connect and connect Health Connect to Welltory (8). Our comparison of Google Fit and Samsung Health explains how the two apps differ.

Don't double-connect. Connect each source by only one method — through a hub or directly, not both — or you'll get duplicate data and inaccurate reports (5, 9).

Step 3: add a Samsung Galaxy Watch (optional)

A Galaxy Watch is the only Android watch that can take HRV measurements in Welltory (1). It needs to be a Galaxy Watch 4 series or newer (2).

1. Pair the watch in the Galaxy Wearable app and check that it shows as connected.

2. In Welltory, go to Menu → Settings → Primary device and tap Install Welltory on my watch under Smartwatch. Google Play opens the app page; install it on the watch.

3. Open Welltory on the watch and allow access to physical activity, vital sign sensor data and background HRV measurements. For automatic measurements, choose All the time.

4. Check your phone for a green checkmark that confirms the connection (2).

Manual readings. Keep the watch charged and connected, open Welltory on the watch, tap the red button, then stay still and breathe normally until it finishes. Results appear in your feed (2).

Automatic readings (Health Monitoring). On Wear OS, the watch can record HRV automatically. Turn it on in Menu → Galaxy Watch (a green checkmark means it's on) and set the minimum time between measurements. The watch only measures when you're calm and still — not while sleeping, moving or working out (2).

Quick access. You can add a Welltory tile (swipe left on the watch face, tap the plus icon) or a complication if your watch face supports it (2).

More about the watch app on our Galaxy Watch HRV page.

Step 4: take your first reading with the phone camera

If you don't have a Galaxy Watch, the camera is how you take an HRV reading on Android (1). It's a deliberate spot measurement, not continuous monitoring.

1. Check that your phone has a flash next to the camera.

2. Cover the right camera and the flash with your fingertip. The placement depends on your model; Welltory shows a diagram. On Samsung Galaxy A52, A53, A54 and S21, S22 and S23 series phones, it's the middle camera (4).

3. Press gently, not hard.

4. Keep still and use the same finger on the same hand each time.

5. Look at the screen. It should glow bright red. If you see your surroundings, try another camera (4).

6. Measure sitting or lying at rest. Movement distorts the signal (4).

Phones where it won't work. Google Pixel phones (all models) and Oppo Reno 10x Zoom: the flash is too far from the camera to light your finger. On those phones, use a compatible chest strap or a Samsung watch instead (4).

For the most comparable readings, measure at the same time each morning, before coffee and before checking messages. Our guide to measuring HRV without a wearable explains the routine.

Which watches and trackers work with Welltory on Android

Sleep on Android. Sleep Analysis builds a sleep score from Samsung Health, and from Fitbit or Garmin Connect when they're connected through Health Connect. The score uses four factors: sleep balance, schedule, stability and heart rate wave, and the heart rate wave baseline needs at least 30 nights of data. You can't enter sleep manually in Welltory; it syncs from your wearable's app (10).

If you're still choosing a watch, our guide to the best Android smartwatches for heart health compares the options.

What's free and what needs Premium

During the three-day trial, you can explore Premium features (6).

After the trial, without a subscription, you keep (6):

• daily indicators;

• one HRV measurement a day with five core indexes (camera or heart rate monitor; the button unlocks again at 5 a.m.) (4);

• on a Galaxy Watch, one manual and one automatic measurement a day (2);

• blood pressure logging with a less detailed analysis;

• sleep duration (without further insights);

• breathing exercises, tests, data syncing and manual entry.

Two limits to know: data older than 30 days is deleted unless you export it or subscribe, and Experiments aren't available (6).

With Premium, you get the full HRV analysis with 21 metrics and unlimited measurements (11). Direct Fitbit and Withings connections are for Premium users (3).

Renewal and cancellation. Subscriptions that renew automatically keep renewing until you cancel; canceling stops renewal for the next billing cycle, and your paid period stays active until it ends. If you bought through Google Play, cancel in your Google Play subscriptions (11). Prices aren't listed in this guide because they vary by country and offer; check the price shown in the app before you subscribe.

Troubleshooting: when data doesn't show up

• Reports don't appear in your feed — In Health Connect, open App permissions, find Welltory and allow all permissions. In Samsung Health, tap the three-dot menu → Settings → Apps, find Welltory and grant all permissions (9)

• Data syncs with a delay — Reconnect Health Connect or Samsung Health to Welltory (9)

• Numbers don't match your watch app, or appear twice — Connect each source by only one method (9)

• The watch shows "Searching" — Charge the watch, check it's connected in Galaxy Wearable, and turn off airplane mode on both devices (2)

• Watch measurement errors — Check Welltory has Activity and Body sensors permissions (Settings → Apps → Welltory → Permissions), relaunch the watch app and try again without moving (2)

• The camera shows your surroundings, not red — Try a different camera, follow the diagram for your model, press gently (4)

• No camera reading on a Pixel phone — The camera method doesn't work on Pixel; use a chest strap or a Samsung watch (4)

Common setup mistakes

• Connecting the same watch twice — once directly and once through Health Connect. You'll get duplicates (5).

• Expecting HRV from a Garmin, Fitbit or Pixel Watch in Welltory. These send activity and sleep; HRV comes from a Galaxy Watch, the camera or a chest strap (1, 3).

• Still relying on Google Fit. Direct connections through Google Fit ended in June 2025 (8).

• Skipping the source app's switch. Health Connect only has data if your watch's app sends it there (7).

• Using Welltory on an Android phone and an iPhone at the same time (1).

• Measuring at random times. Your readings are easiest to compare when they're taken the same way each day.

• Letting free-plan history expire. Export what you want to keep before it passes 30 days (6).

Living with Welltory on Android: the questions people ask next

Does Welltory work with Samsung Galaxy Watch?

Yes. Galaxy Watch 4 series and newer on Wear OS can take manual and automatic HRV measurements with the Welltory watch app, and send activity and sleep through Samsung Health (2, 1).

Does Welltory work with Pixel Watch?

Partly. Pixel Watch is listed for activity tracking, and HRV measurements are currently unavailable on Pixel Watch devices running Wear OS 6 (3, 2). If you also have a Pixel phone, the camera method won't work either, so a chest strap is the way to take HRV readings (4).

Does Welltory work with Fitbit on Android?

Yes, for activity, and for sleep through Health Connect. Welltory doesn't take HRV from Fitbit. A direct Fitbit connection is available to Premium users (3, 10).

Does Welltory work with Garmin Connect?

Through a hub only: Garmin has no direct connection. Through Health Connect or Samsung Health, Welltory receives Garmin workouts, stress level, energy level, sleep and other metrics (5).

Is Welltory free on Android?

There's a free version. After a three-day trial, you can take one HRV measurement a day with five core indexes and keep logging, syncing and breathing exercises; history is kept for 30 days. Premium is a paid subscription with unlimited measurements and the full 21-metric analysis (6, 11).

How do I delete my account?

In the app, go to Menu → Account → Delete Account. If you have an active Premium subscription, wait for it to end or ask support to move you to the free plan first (11).

Before you blame yourself

After a week of readings, it's common to think: "My numbers are worse than everyone else's — I must be doing something wrong." Before you go there, look at your data.

The feeling: "My HRV is low and jumps around every day."

The cause you can often see: readings taken at different times, after coffee, while talking, or with a finger pressed too hard. HRV also varies a lot between people of the same age, so your number only means something next to your own earlier readings. Our guide to a good HRV range explains why.

One lever for one to two weeks: fix the conditions, not the number. Same time each morning, same position, same finger, before coffee. After two weeks, look at the weekly average, not single days.

If your readings stay unusually low and you also feel unwell, that's a reason to talk with a doctor, not a reason to blame yourself.

When to see a doctor

Welltory can't tell you whether something is wrong with your heart. See a doctor if:

• You feel a racing, pounding or irregular heartbeat, or you faint or nearly faint.

• You're short of breath with light activity, or you have new chest discomfort with exercise.

• Your resting heart rate stays well above your usual level for more than a week without a clear reason.

• You feel exhausted most days for weeks despite enough sleep.

Phone-camera readings are unreliable if you have an arrhythmia (4), so don't use them to rule anything out.

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 (12).

How to bring this up with your doctor

What to ask for, by name. For palpitations or an irregular pulse: "Can we check this with a 12-lead ECG, and would a heart monitor I wear for a few days help?" For lasting fatigue: "Could we check thyroid function and a basic blood panel?"

What to bring. A CSV export of your readings: in the Welltory web app, open the Dashboard, choose a chart, pick the time range and tap Export (13). Add notes on symptoms, sleep, caffeine and medications for the same weeks.

What to say if you're brushed off. "I know an app isn't a diagnosis. I'm not asking you to trust it. I'm asking whether these symptoms 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 or treat any condition, it isn't an ECG and can't replace one (4), and readings may not be accurate if you're under 18 or pregnant (1).

What it does on Android, as described in the Help Center:

• HRV readings from a Galaxy Watch (manual or automatic), your phone camera on supported phones, or a compatible chest strap (2, 4, 3).

• Data from several devices in one app through Health Connect or Samsung Health (5).

• A sleep score from Samsung Health, Fitbit or Garmin data (10).

• A record you can export as CSV for your doctor (13).

How we made it

This guide describes our own app. We based it on Welltory Help Center articles on getting started, Health Connect, the move from Google Fit, data sources, device compatibility, Samsung watch measurements, camera measurements, sleep analysis on Android, the free trial, subscriptions, data source troubleshooting and data export, plus the American Heart Association's warning signs page. Search questions came from what people in the United States most often ask about Welltory on Android. For the product section, we checked every function against the Welltory Help Center on November 8, 2026.
