How to Transfer Withings Data to New Phone: Complete Guide

1. Who this guide helps

This guide is for anyone who owns a Withings device — a ScanWatch, ScanWatch 2, ScanWatch Light, Steel HR, Steel, Move, Pulse HR, Body smart scale, BPM blood pressure monitor, Sleep analyzer, or Thermo — and is moving from one phone to another. Whether you are upgrading from an older iPhone to a newer one, switching from Android to iPhone (or the reverse), or setting up a replacement phone after your old one was lost, stolen, or damaged, the process is the same in principle: your measurements and history are tied to your Withings account, not to the phone in your hand. (Source: support.withings.com)

It is also for the cautious planner. If you are about to buy a new phone and want to make sure years of weight, blood pressure, sleep, and activity data survive the switch, the five-minute preparation section below is worth doing before you wipe or hand over the old phone.

Quick fact: Withings is a health-focused brand, not a sport-watch brand. Unlike the Coros, Suunto, and Polar guides on this site — which deal mainly with training watches — this article also covers connected scales, blood pressure monitors, sleep analyzers, and thermometers, because all of them live in the same Withings account and move together when you switch phones.

2. The key idea: your Withings account holds the history

Here is the single most important thing to understand before you touch anything: Withings stores your measurements in your online Withings account, not on the phone itself. When your watch or scale syncs, it sends data through the Withings app to Withings’ servers, and your app displays that cloud history on demand. That is why “transferring” your Withings data is mostly about signing in, not about copying files or making backups.

In practical terms, this means three things:

• Sign in with the same account and your history comes back by itself. Years of weight readings, blood pressure measurements, sleep sessions, and workouts reappear in the app once the same account is signed in, because the app pulls them from your account.
• Creating a new account starts you at zero. If you accidentally register with a different email address or sign in with a different login method, you will see an empty dashboard. The data is not gone — it is sitting in your original account waiting for you to sign in correctly.
• The only data at risk is whatever has not synced yet. Anything your watch measured but has not yet sent to the app — for example, the last day or two of steps if you have not opened the app — lives only on the device. So the one genuine preparation step is to sync the old phone fully before you let it go.

This is fundamentally different from moving between phone ecosystems for phone-native health data, where encrypted phone backups carry the records. With Withings, the phone is mostly a window into your account, and the device just needs to be paired again so it can keep syncing into that account.

Tip: Because the account is the master record, this guide’s method works across platforms. Moving from iPhone to Android or Android to iPhone does not require anything special for the Withings side — the account is platform-neutral. What changes are the phone-side pieces (Bluetooth settings, Apple Health or Google Health links, notification permissions), which this guide covers separately.

If you also track with other platforms, this site has companion transfer guides with the same sign-in-and-re-pair method but brand-specific steps: transferring Huawei Health data to a new phone, transferring Coros data to a new phone, and transferring Suunto data to a new phone.

3. Before you start: the five-minute checklist

Do these on the old phone before you wipe, sell, trade, or lose access to it. Each takes seconds and prevents the most common “where did my data go?” panics.

• Open the Withings app and force a sync. Open the app, let it finish syncing with each device (watches sync over Bluetooth when in range), and confirm your most recent measurements appear. For a watch, keep it nearby and on your wrist; for a scale, step on it once and confirm the reading appears in the app.
• Confirm which email address your account uses. In the app, open your profile or account settings and check the exact email address. Write it down or confirm you can receive mail at it. This is the single credential that matters.
• Test that you can log in. If you signed up with an email and password, make sure you remember the password or reset it now while you still have the old phone. If you used a social sign-in (Apple or Google), confirm which one.
• Charge both phones and the watch to at least 50%. Pairing and syncing over Bluetooth drains battery on both ends. A mid-pairing shutdown is a classic cause of half-finished pairings.
• Check the new phone’s OS version. The Withings app needs a reasonably current operating system (the pairing guides document iOS 12 or higher and Android 6 or higher for the general app; newer ScanWatch models need iOS 15 or Android 9 or higher). If the new phone is fresh out of the box, install its pending system updates first.
• Turn on Bluetooth and Wi-Fi on the new phone. Pairing uses Bluetooth; the app also uses Wi-Fi or mobile data to sign you in and pull your account history.

Stop for safety: Never sign in to your Withings account on someone else’s phone “just to check something,” and never install your device on a phone you do not own. Withings’ own product documentation warns against installing the device on a smartphone you do not own, and signing in on a borrowed phone can leave your health data in someone else’s app.

4. Transfer methods compared

There is really one official method, but people arrive at it from different situations. This table helps you find your row.

The takeaway: the standard method works for every situation and every platform. The other rows exist only so you do not waste time on approaches that cannot do what the account sign-in already does.

5. Step 1: sync everything on the old phone

On the old phone, open the Withings app and let every device sync completely:

• Watch: wear it or keep it close, open the app, and wait until the latest activity and sleep data appear. The app syncs with the watch over Bluetooth when the two are in range.
• Scale: step on the scale and confirm the reading appears in the app.
• Blood pressure monitor: if you have recent unsent readings stored on the cuff, sync them now.
• Sleep analyzer: confirm the last night’s sleep session is visible.

If a device will not sync, do not panic — try toggling the phone’s Bluetooth off and back on, then reopening the app. Only after the most recent readings are visible should you move on. Whatever has not synced by the time the old phone is gone stays on the device’s memory until it can sync again — and if the device is also gone, those unsynced readings are lost.

Tip: The scales, blood pressure monitors, and Sleep analyzers hold only a limited number of unsynced readings in memory. If you have been away from the app for weeks, sync before the number rolls over — oldest unsynced readings are the first to be overwritten.

6. Step 2: install the Withings app and sign in on the new phone

1. On the new phone, download the official Withings app (formerly known as Health Mate) from the App Store (iPhone) or Google Play (Android). Use only the official app stores — Withings’ documentation explicitly points users to official stores, and third-party app files are a malware risk.
2. Open the app and choose sign in, not “create account.”
3. Enter the exact same email address and login method you used on the old phone. If you originally signed up with Apple or Google sign-in, use that same option — an email + password login to the same address may create a mismatch depending on how the account was first created.
4. Complete any verification the app asks for (email code or similar), and let the app finish loading. Your dashboard, history graphs, and past measurements should start appearing. This can take a minute on first sign-in.

Stop for safety: If your dashboard is empty after signing in, you almost certainly signed in to the wrong account — a different email, or a social login instead of email + password. Do not reset your watch, do not delete anything, and do not create a second account to “fix” it. Sign out, double-check the exact email in your old app (or your old phone’s settings), and sign in again with the original credentials. An empty dashboard is a login problem, not a data-loss problem.

7. Step 3: pair your device again inside the app

Signing in restores your history, but your watch or scale is still paired to the old phone’s Bluetooth, not the new one. You must pair it again — and the pairing has to happen inside the Withings app, not in the phone’s Bluetooth settings. Pairing a Withings device through the phone’s system Bluetooth menu creates a connection the app cannot use, which is one of the most common reasons people think “pairing failed.”

7.1. Watches (ScanWatch, ScanWatch 2, ScanWatch Light, Steel HR, Move)

1. In the Withings app, open the Devices tab and choose Install a device.
2. Select the device category (for example, “Watches”) and then your exact model.
3. On the watch itself, prepare it for pairing. On a ScanWatch, go to Settings > Phone > Pair a new device (press the crown to wake the screen first). Other models show a setup message on screen or flash an LED when ready — follow the app’s prompts for your model.
4. Follow the on-screen instructions. The app will search over Bluetooth; when it finds your watch, it may show a pairing code on the watch screen that you confirm or type into the app.
5. Finish the in-app setup steps (time alignment on analog models, goal and notification preferences).

After pairing, the watch syncs automatically with the app whenever it is in Bluetooth range of the phone, just as it did before.

7.2. Scales (Body, Body+, Body Scan, and older models)

Pair the scale the same way: Devices > Install a device, choose the scale category, and follow the prompts (usually stepping on the scale when asked). Once paired, your weigh-ins resume flowing into the same account, and your weight history graph continues uninterrupted.

7.3. Blood pressure monitors (BPM Core, BPM Connect)

Use Devices > Install a device and select the blood pressure monitor. Follow the Bluetooth pairing prompts. Your earlier readings remain in the account; new measurements simply continue the record.

7.4. Sleep analyzer and Thermo

The Sleep analyzer pairs through Devices > Install a device like the others. Note that the Sleep analyzer can also sync over Wi-Fi — if you set it up on your home Wi-Fi, it can send sleep sessions even when the phone is not nearby, so confirm the Wi-Fi step during installation. Thermo pairs the same way; keep in mind it stores only recent readings on-device, so sync promptly.

Quick fact: Withings watches can only be actively paired with one phone at a time. If the watch is still paired to the old phone, the new phone’s app may fail to find it or the pairing may stall — which is why the “Pair a new device” step on the watch itself (Section 7.1) matters: it releases the old bond and makes the watch discoverable again.

8. What comes back automatically — and what does not

Once you are signed in with the correct account, this is what to expect.

9. Rebuild the phone-side links after pairing

With the account signed in and the device paired, reconnect the bridges between Withings and the rest of your phone.

9.1. Apple Health (iPhone)

Withings supports syncing measurements to Apple Health, but iPhone users should know about a documented quirk: there is an iOS restriction that can prevent automatic syncing, and Withings’ own customer service documents a specific refresh sequence to work around it. After re-linking Health in the app (Profile, then the Apple Health option, turning on the categories you want):

1. Open the Withings app.
2. Open Apple Health.
3. Return to the Withings app and swipe down from the top to force a refresh.

Also make sure Background App Refresh is enabled for the Withings app (iPhone Settings > General > Background App Refresh), because Withings notes that transfers from the app to Apple Health depend on it. If you ever fully reset the connection, Withings’ documented order is: turn all categories off in Apple Health’s app settings for Withings, uninstall the Withings app, restart the phone, reinstall, sign in, then turn the categories back on — and only then expect the green check mark confirming the link.

9.2. Google Health Connect (Android)

On Android, re-authorize the Withings app’s connection to Google’s health platform in the app’s sharing or integration settings, then confirm in the phone’s health settings that the Withings app is allowed to read and write the data types you want. Exact menu labels change with app updates, so follow the prompts as they appear rather than an old screenshot.

9.3. Notifications, alarms, and watch settings

Open the device’s page in the app and walk through its settings once: notification forwarding, alarms, and display preferences. Phone-side permissions (notifications, location for workout GPS, background activity) are granted per phone, so re-approve them when the new phone asks.

Tip: Do this permissions walk-through while the watch is on your wrist and nearby. Some settings (like notification forwarding) only take effect on the next sync, so send yourself a test notification and confirm the watch buzzes before you consider the job done.

10. No old phone? The lost, stolen, or broken path

If the old phone is gone, the transfer still works — you just skip Section 5, because there is no final sync to perform. Sign in to your Withings account on the new phone (Section 6) and pair the device (Section 7). Everything that had synced to your account before the old phone disappeared will be there.

The honest costs of this path:

• Unsynced measurements are gone for good. Anything your watch or scale measured after the last successful sync — the last day or two of activity, a weigh-in that never uploaded — lived only on the device or the dead phone. If the device itself is also gone, those readings cannot be recovered.
• The watch may need to be released from the old pairing. If the watch was still bonded to the lost phone, put the watch into its “pair a new device” state (Section 7.1). If the watch refuses because it is stuck on the old bond, a factory reset of the watch is the last resort — and that erases whatever unsynced data remains on the watch. Only reset after you have accepted that loss.
• Scales and monitors are simpler. A scale or blood pressure monitor with no phone nearby is just waiting to be paired; install it as a new device in the app and it resumes adding to your existing history.

Stop for safety: If your phone was stolen, change your Withings account password from a trusted device or computer as soon as possible, and sign out any sessions you do not recognize. Health data is sensitive personal data — treat a stolen phone with a signed-in health app the same way you would treat a stolen wallet.

Honest diagnosis matters more than speed. This table keeps expectations straight.

13. Hypothetical examples

(The following are hypothetical illustrations, not customer stories.)

Maya’s careful Android upgrade. Maya has used a ScanWatch and a Body scale for three years. Before handing her old Pixel to a trade-in program, she opens the Withings app, confirms last night’s sleep and this morning’s weigh-in are visible, and double-checks the email on her account. On the new phone she installs the Withings app from Google Play, signs in with that same email, and sees her full history return. She then goes to Devices, installs the ScanWatch (using “Pair a new device” on the watch itself), installs the scale, re-links Google Health Connect, and sends herself a test notification. Total time: about twenty minutes, zero data lost.

Daniel’s stolen-phone scramble. Daniel’s phone is stolen on a trip, along with two days of unsynced runs on his Steel HR. He buys a replacement, installs the Withings app, and signs in with his original account — everything up to the last sync is there. The two unsynced runs are gone, and he accepts that rather than chasing them. He changes his Withings password from his laptop first, then pairs the Steel HR fresh in the app. His Apple Health link needs the refresh sequence before new data flows, which he does once and then forgets about.

Tip: Maya’s outcome and Daniel’s outcome differ only because of Section 5 — the final sync. The transfer mechanism itself is identical. That is the whole lesson of this guide: sync before you switch, sign in with the same account, pair inside the app.

14. When to stop and get a local assessment

Stop troubleshooting and get help if any of these are true:

• The watch will not power on, charge, or show any screen at all — that is a hardware or battery issue, not a transfer issue.
• Pairing fails on two different phones after you have followed Section 11 — the watch’s Bluetooth radio may have failed.
• The scale gives wildly inconsistent readings or will not power on — check the batteries first, then consider service.
• You see physical damage: a cracked watch screen, a swollen battery, or a scale with a damaged glass top. Do not use a swollen battery device at all.

Quick fact: A transfer problem is almost never a repair problem. If the device worked on the old phone yesterday, it is a pairing or account issue — work through Sections 11 and 12 before assuming anything is broken. If the device itself is genuinely damaged, a local shop can assess it: Las Vegas Phone Repair & Accessories, 7400 Las Vegas Blvd S, Unit TT42, Las Vegas, NV 89123, (424) 406-6202 — open 10 AM to 8 PM; call ahead to confirm today’s hours.

15. Frequently asked questions

Does my Withings data move automatically when I switch phones?

Your synced history moves automatically in the sense that it is already in your Withings account — signing in with the same account on the new phone brings it back without any export or import. What does not move automatically is the Bluetooth pairing (you re-pair each device in the app) and the phone-side links (Apple Health, Google Health Connect, notifications, third-party integrations), which you re-authorize on the new phone.

I signed in but my history is empty. Is my data gone?

Almost certainly not — you are almost certainly signed in to the wrong account. Sign out, verify the exact email address and login method from your old phone or your email records, and sign in again. Do not create a new account, do not reset your watch, and do not delete anything. An empty dashboard after a phone switch is a login mismatch in the vast majority of cases.

Can I transfer without the old phone?

Yes. Install the Withings app on the new phone, sign in with your original account, and pair the device fresh (Section 7). Everything that had synced to your account is preserved. The only things you lose are measurements that were never synced — and if the old phone is gone, those cannot be recovered.

Do I need to unpair the device from the old phone first?

Not strictly, but it helps. Putting the watch into its “Pair a new device” state releases the old Bluetooth bond so the new phone can find it. If you no longer have the old phone, the watch-side step accomplishes the same thing.

Why is my Apple Health not getting new Withings data?

This is a known, documented quirk: an iOS restriction can block automatic syncing. Use the refresh sequence — open the Withings app, open Apple Health, return to the Withings app and swipe down to force a refresh — and confirm Background App Refresh is enabled for the Withings app in the iPhone’s settings. If you rebuilt the connection, follow the documented order: turn categories off, reinstall the app, restart the phone, sign in, then turn categories back on.

Do scales and blood pressure monitors transfer the same way?

Yes — they are all devices on the same Withings account. Sign in on the new phone and install each device again via Devices > Install a device. Their histories are already in the account, so weigh-ins and blood pressure readings continue the same graphs.

I switched from iPhone to Android (or the reverse). Anything special?

On the Withings side, no — the account is platform-neutral. Re-pair the device in the app exactly as described. What changes are the phone-side pieces: on Android you re-link Google Health Connect and grant Android’s Bluetooth/location permissions; on iPhone you re-link Apple Health and enable Background App Refresh. Review notification permissions on the new platform too.

How long does Withings keep my data in the cloud?

Withings does not publish a simple “we keep data for X years” figure in the materials reviewed for this guide, and you should not rely on an invented number. In practice, long-standing accounts retain years of history once synced. The practical rule is the same as ever: sync regularly so your account — not a single device or phone — is the master copy of your health record.
