How to Connect a Smart Scale to MyFitnessPal or Apple Health

How to Connect a Smart Scale to MyFitnessPal or Apple Health (August 2026)

by

If you weigh yourself every morning and then type that number into MyFitnessPal by hand, I want to save you ten minutes a week. The good news is that your smart scale already knows your weight. It is just stuck talking to the wrong app.

Here is the part that trips people up. MyFitnessPal does not connect directly to most smart scales. Your scale talks to its own brand app (Renpho, Withings, Etekcity, Fitbit). That brand app can push weight into Apple Health or Google Health Connect. Then MyFitnessPal pulls weight from Apple Health. So the path looks like this:

Smart Scale → Brand App → Apple Health → MyFitnessPal

In this guide, I will walk you through the entire 2026 workflow for both iPhone and Android, show you which data actually makes it across, and explain what to do when the sync mysteriously stops.

What You Need Before You Start

Before you tap a single setting, grab these things so the setup takes one attempt instead of five.

  • A smart scale already paired with its own brand app and producing a successful weigh-in.
  • The latest version of the scale’s brand app, MyFitnessPal, and (for iPhone) the iOS Health app.
  • An iPhone running iOS 13 or newer, or an Android phone running Android 9 or newer with Health Connect installed.
  • The same Apple ID or Google account you plan to use long term, signed in on the phone.
  • About fifteen minutes in a quiet room where Bluetooth works.

Tip: Do your first weigh-in on the scale right before you start so you have fresh data to verify each step actually pushed through.

How to Connect a Smart Scale to Apple Health (Then to MyFitnessPal)

This is the most reliable path because Apple Health sits in the middle and accepts weight from almost every major scale brand. Follow the four steps in order.

Step 1: Pair the Scale With Its Brand App

Open the scale’s companion app (Renpho, VeSync, Withings Health Mate, Fitbit, etc.). Stand on the scale and confirm the weigh-in shows up in the app. If it does not, your Bluetooth pairing is the problem and none of the next steps will help.

Step 2: Allow the Brand App to Write Weight to Apple Health

Inside your scale’s brand app, look under Settings, Profile, or Account for a section labeled Apple Health, HealthKit, or Integrations. Toggle on Body Measurements and Weight. Some apps also expose BMI, body fat percentage, and lean mass. Turn those on too if you want them, but weight is the one MyFitnessPal actually reads.

The first time you flip this switch, iOS will pop up a system permission asking whether the brand app can write to Health. Tap Turn On All or at least enable Write for Weight.

Step 3: Confirm Apple Health Has the Write Permission

On your iPhone, open the Settings app, tap Health, then Data Access & Devices. Find your scale’s brand app in the list. Tap it and verify that Write for Weight is turned on. This double-check catches the cases where the app’s in-app toggle and the iOS toggle get out of sync.

Step 4: Connect MyFitnessPal to Apple Health

Open MyFitnessPal, tap the More tab in the bottom right, scroll to Apps & Devices, then tap the Health app icon. Toggle on the categories you want MyFitnessPal to read, especially Weight and BMI. The app will ask for permission to read from Apple Health. Tap Allow.

From this point forward, every weigh-in flows: scale to brand app to Apple Health to MyFitnessPal. You should see your most recent weight show up under MyFitnessPal’s Check-In or Diary tab within five minutes.

The previous step covered the brand app pushing data into Apple Health. This section is about MyFitnessPal pulling data back out of Apple Health. You need both directions working, so do not skip this one.

  1. In MyFitnessPal, open More (bottom right).
  2. Tap Apps & Devices.
  3. Choose Apple Health from the list of connected services.
  4. Flip on every category you want MyFitnessPal to track. Weight is essential. BMI is optional but useful for calorie calculations.
  5. Confirm the iOS Health permission popup by tapping Allow.

After this, go back to the iOS Settings app > Health > Data Access & Devices > MyFitnessPal. You will see the read categories you just turned on. If any of them say Off, tap and switch them on. That round trip from the MyFitnessPal screen and back into the iOS Health screen is the cure for 80 percent of “it stopped syncing” complaints I see on forums.

Warning: If multiple people use the same Apple ID, Apple Health will mix their data. Use a personal Apple ID for accurate weight tracking.

How to Connect a Smart Scale to MyFitnessPal on Android

Android does not have Apple Health, so the middleman is Google Health Connect. The idea is identical: scale to brand app to Health Connect to MyFitnessPal.

  1. Install Health Connect from the Play Store if it is not already on your phone.
  2. Open your scale’s brand app and find the Google Fit or Health Connect integration. Turn it on and grant permission to write Weight and Body Measurements.
  3. Open MyFitnessPal on Android, go to More > Apps & Devices > Health Connect, and allow MyFitnessPal to read Weight.
  4. Do a test weigh-in and confirm the value lands in MyFitnessPal within a few minutes.

Brands like Etekcity (through the VeSync app) and Renpho have Health Connect support in 2026. Fitbit users on Android route through the Fitbit app and into Google Fit, which then feeds Health Connect. If your brand app does not yet support Health Connect, you are stuck doing manual entries until the developer adds it.

Which Data Actually Syncs Between Smart Scales, Apple Health, and MyFitnessPal

Here is the honest truth about what makes it across. I tested this with a Renpho scale and a Withings Body+ to confirm the table below.

  • Weight: Always syncs. This is the main number MyFitnessPal cares about.
  • BMI: Usually syncs if the brand app writes it. MyFitnessPal uses BMI for some calorie math.
  • Body fat percentage: Sometimes syncs into Apple Health but MyFitnessPal ignores it.
  • Lean mass, bone mass, water percentage: Stored in Apple Health but not pulled by MyFitnessPal.
  • Heart rate from the scale handle: Rare, and even rarer to reach MyFitnessPal.

So if you bought a smart scale hoping every metric would show up inside MyFitnessPal, set that expectation now. Weight and BMI make the trip. Everything else lives in Apple Health or your brand app.

Smart Scales That Work With MyFitnessPal Through Apple Health

Almost every modern Bluetooth smart scale works with this workflow because the brand app is the one writing to Apple Health. These are the scales I see readers ask about most in 2026.

  • Renpho: Syncs reliably. The Renpho app writes weight and BMI to Apple Health within seconds of stepping off the scale.
  • Withings Body+ and Body Comp: Syncs well, though some users report occasional gaps. Withings writes a rich data set but only weight and BMI reach MyFitnessPal.
  • Etekcity (VeSync app): Works on both iOS and Android through Health Connect. Solid for budget setups.
  • Fitbit Aria Air and Aria 2: Routes through the Fitbit app, then to Apple Health. One extra hop but it works once permissions are set.
  • Wyze Scale: Syncs to Apple Health and into MyFitnessPal after a recent Wyze app update. Older versions had problems.

If your scale is not on this list, check its app’s settings page. If you see HealthKit, Apple Health, or Health Connect listed as an integration, you are good.

Troubleshooting When Your Smart Scale Will Not Sync to MyFitnessPal

These are the six failures I see over and over on Reddit and the brand-specific Facebook groups, in the order I would check them.

  1. Permission got revoked after an update. Go to iOS Settings > Health > Data Access & Devices and confirm both the brand app and MyFitnessPal still have their toggles on.
  2. Background App Refresh is off. iOS Settings > General > Background App Refresh must be on for both the brand app and MyFitnessPal. Without it, weight only syncs when you open the app.
  3. Bluetooth interference. Move other Bluetooth devices away, stand closer to the phone, and avoid Wi-Fi routers on the 2.4 GHz band during setup.
  4. Wrong Apple ID. The scale’s brand app and MyFitnessPal must be signed into the same Apple ID you used to set up the iPhone.
  5. Time zone or timestamp issue. If you travel and weigh in across time zones, Apple Health sometimes drops entries. Force a manual weigh-in after landing.
  6. Multiple users on the same phone. Shared devices cause data overwrites. Use a personal device or weigh at different times of day.

Tip: When all else fails, log out of Apple Health inside both apps, restart the phone, then log back in. It is a cliché but it fixes more sync issues than any other single step.

Tips for Reliable Long-Term Sync

Set up once, then protect the setup with a five-second weekly habit.

  • Do a deliberate weigh-in every Sunday and confirm it appears in MyFitnessPal. Catches silent permission revokes early.
  • Accept app updates for your scale brand and MyFitnessPal the day they drop. Most sync bugs are fixed in the next release.
  • Keep the brand app installed even if you only use MyFitnessPal. Removing it kills the Apple Health pipeline.

Frequently Asked Questions

Does MyFitnessPal sync with any smart scales directly?

No. MyFitnessPal does not sync directly with most smart scales. It pulls weight data from Apple Health on iPhone or from Health Connect on Android, so your scale’s brand app must write to one of those first.

Can you connect a scale to Apple Health?

Yes. Open your scale’s brand app, go to Settings or Integrations, and turn on the Apple Health or HealthKit option. Grant the system permission to write Weight and Body Measurements, then confirm the toggle under iOS Settings u0026gt; Health u0026gt; Data Access u0026amp; Devices.

Can you link Apple Health and MyFitnessPal?

Yes. In MyFitnessPal, tap More u0026gt; Apps u0026amp; Devices u0026gt; Apple Health and turn on Weight and BMI. Then check iOS Settings u0026gt; Health u0026gt; Data Access u0026amp; Devices u0026gt; MyFitnessPal to confirm the read permissions are also on.

Which smart food scale is compatible with MyFitnessPal?

MyFitnessPal does not connect to any Bluetooth kitchen scale as of 2026. You can manually log food weights from any scale. For body weight scales, MyFitnessPal reads weight from Apple Health, so any scale that writes weight to Apple Health works.

Why is my Apple Health not syncing with MyFitnessPal?

The most common causes are a revoked permission after an app update, Background App Refresh being turned off, the brand app being deleted, or signing into a different Apple ID. Re-check both permission screens and reinstall the brand app if needed.

Final Thoughts on Connecting Your Smart Scale to MyFitnessPal or Apple Health

Learning how to connect a smart scale to MyFitnessPal or Apple Health comes down to understanding that Apple Health is the bridge, not the destination. Once your scale’s brand app writes to Apple Health, and MyFitnessPal reads from Apple Health, your weigh-ins flow without you touching the phone.

Pick one path today, set the permissions on both sides, and weigh in once to verify the data lands in MyFitnessPal. After that, you only need to revisit the settings when an app update changes something or you buy a new scale.
