I need a smart scale that syncs body composition data to my health app over Wi-Fi.

If you want Wi-Fi + body composition + automatic syncing to a health app, I’d narrow it to these:

• Withings Body Smart - $129.95 (Best Buy)
• Withings Body Comp - $229.95 (Best Buy)
• Garmin Index S2 - $199.99 (Garmin)
• RENPHO Smart Scale - $169.99 (Best Buy)

My picks

• Best overall: Withings Body Smart — ~$130. It measures weight, BMI, body fat, water, muscle and bone mass, plus visceral-fat and cardiovascular metrics. It has Wi-Fi, and Withings supports Apple Health and other health platforms. Current testing/reviews favor it as a particularly well-rounded Wi-Fi scale.

• Withings Body Smart - $129.95 (Best Buy)

• Best for more detailed body composition: Withings Body Comp — ~$230. This is the upgrade if you care more about body-composition detail and trend tracking. It adds more sophisticated measurements, including cardiovascular-related metrics, while retaining Wi-Fi syncing and broad app compatibility.

• Best if you use Garmin: Garmin Index S2 — ~$200. It automatically syncs over Wi-Fi to Garmin Connect and tracks body fat, muscle mass, bone mass, BMI and more. It's particularly compelling if your watches/workouts already live in Garmin's ecosystem.

• Garmin Index S2 - $199.99 (Garmin)

• Best budget option: RENPHO. There are inexpensive RENPHO models with lots of body metrics and Apple Health integration, but check the exact model carefully: many cheaper RENPHO scales are Bluetooth-only, so they don't meet your Wi-Fi requirement. Current Wi-Fi-capable models exist.

If you're using Apple Health, I'd buy the Withings Body Smart. It hits the sweet spot of price, Wi-Fi automation, body-composition data, and Health app integration.

One caveat: body-fat, muscle, visceral-fat, etc. readings from consumer scales are BIA estimates, so they're much more useful for tracking trends than treating the individual numbers as clinically precise.

If you tell me iPhone/Apple Health, Android/Google Health, or Samsung Health, plus your budget (e.g. under $100 / $150 / $250), I can narrow it to the best 2–3 choices.

Getting a Wi-Fi-connected smart scale is a game changer because your measurements upload to the cloud automatically—meaning you don't need your phone nearby when you step on it.

Top smart scales featuring Wi-Fi connectivity and robust body composition syncing include:

To help narrow down the best choice for you:

• Which health app are you using as your primary dashboard (Apple Health, Google Health Connect, Fitbit, Garmin Connect, etc.)?
• Are you looking for a budget-friendly option or a premium model with advanced metrics?

If Wi-Fi syncing + body composition + automatic health-app integration are your priorities, I’d narrow it to these:

• Withings Body Smart - $129.95 (Best Buy)
• Garmin Index S2 - $199.99 (Garmin)
• Withings Body Comp - $229.95 (Apple)
• RENPHO Wi-Fi 8-Electrode Scale - $169.99 (Best Buy)

My pick: Withings Body Smart

• Withings Body Smart - $129.95 (Best Buy)

At about $130, the Withings Body Smart is the best balance for most people. It uses Wi-Fi + Bluetooth, automatically syncs measurements, and tracks weight, body fat, muscle, water, bone mass, BMI, visceral-fat index, and heart rate. It also integrates with Apple Health and other health platforms.

Other good choices

• Garmin Index S2 — Best if you already use Garmin. It syncs over Wi-Fi to Garmin Connect and tracks weight, body fat, BMI, skeletal muscle and more.
• Withings Body Comp — Worth the extra money if you want more advanced cardiovascular/body-composition features. It's currently around $200–$230.
• RENPHO 8-electrode Wi-Fi scale — A more feature-heavy alternative with Wi-Fi and Apple Health compatibility.

One important caveat: body-fat, muscle, visceral-fat and similar numbers from home scales are BIA estimates. They're much more useful for watching trends over time than treating any individual reading as medically precise.

If you tell me whether you use Apple Health, Google Health Connect, Fitbit, or Samsung Health, I can pick the best one specifically for your setup.

For reliable Wi-Fi syncing (so your phone doesn't need to be right next to you or have the app open when you step on), a true Wi-Fi-enabled smart scale is the way to go.

Top recommendations matching your criteria for Wi-Fi body composition syncing:

Add to listWithings Body Smart — This is widely considered the gold standard for seamless Wi-Fi and Bluetooth syncing. It tracks 8 precise metrics (including body fat, muscle mass, water percentage, and visceral fat) plus heart rate. It automatically recognizes up to 8 users and syncs effortlessly over Wi-Fi directly to the Withings app, with clean native integration into Apple Health and Google Fit . You can view details or buy it directly via the Apple Withings Body Smart Page or Withings Store.

Add to listGarmin Index S2 — If you are already tied into the Garmin ecosystem or want a sleek, high-resolution color screen that displays trend graphs right on the glass, this is a fantastic option. It measures weight, body fat percentage, BMI, water percentage, bone mass, and skeletal muscle mass, syncing over Wi-Fi directly to your Garmin Connect Account.

Add to listEufy Smart Scale P2 Pro — A slightly more budget-friendly alternative that still supports robust Wi-Fi and Bluetooth connectivity. It captures 16 detailed body composition metrics and syncs smoothly with third-party health apps like Apple Health, Google Fit, and Fitbit.

To help narrow down the best choice for you:

• Which specific health app are you trying to sync with (e.g., Apple Health, Google Health Connect, Fitbit, Garmin Connect)?
• Do you have a preference on budget or extra features like a color display?

To get body composition data synced over Wi-Fi (meaning your data transfers automatically to the cloud and your health app without needing your phone next to you on the bathroom floor), you'll want a Wi-Fi-enabled smart scale rather than a basic Bluetooth-only model.

The top Wi-Fi smart scales tailored for body composition tracking and third-party app syncing (like Apple Health, Google Health Connect/Fit, or Fitbit) include:

Which specific health app (e.g., Apple Health, Garmin Connect, Fitbit) are you trying to sync with, and do you prefer a budget-friendly option or a high-end clinical-grade model with a handle?

If Wi-Fi syncing + body composition + health-app integration are your priorities, I’d narrow it to these:

Withings Body Smart

$129.95

1. Withings Body Smart — best overall

• Wi-Fi + Bluetooth automatic syncing
• Tracks body fat, muscle, water, bone mass, BMI, visceral fat, BMR and heart rate
• Works with Apple Health and other health platforms
• Up to 8 users
• Current listed price: $129.95
• Excellent choice if you want broad health tracking without being tied to a fitness-watch ecosystem.

$199.99

2. Garmin Index S2 — best for Garmin users

• Wi-Fi syncing to Garmin Connect
• Tracks weight, body fat, muscle mass, bone mass, body water and BMI
• Up to 16 user profiles
• Best fit if you already use a Garmin watch and want everything in Garmin Connect.

• 8-electrode design and 13 body-composition metrics
• Includes a color display and heart-rate measurement
• Currently listed around $120
• Worth considering if you want more extensive body analysis for less than the premium Withings models.

My pick: Withings Body Smart. It hits the sweet spot of Wi-Fi automation, body-composition data, and broad health-app compatibility. Recent testing also rated it ahead of the Garmin Index S2 for general-purpose health tracking.

One important caveat: body-fat, muscle and similar numbers from consumer scales are estimates. They're much more useful for watching trends over time than treating an individual reading as an exact measurement.

If you tell me whether your health app is Apple Health, Google Health Connect/Google Fit, Samsung Health, or Fitbit, I can narrow this to the best 2–3 options for that specific app.

Getting a Wi-Fi-connected smart scale means you can step on and walk away—your data automatically syncs to the cloud and pushes straight to your favorite health app (like Apple Health, Google Fit, or Fitbit) without needing your phone nearby.

Top Wi-Fi smart scales that handle body composition and app syncing seamlessly include:

Withings Body Smart (~$130): Widely considered the gold standard for everyday users. It measures weight, body fat/muscle mass percentage, water percentage, visceral fat, and heart rate. It features automatic Wi-Fi syncing and a crisp color screen, and it integrates smoothly with Apple Health and Google Fit via the Withings app. (Withings also offers the high-end Body Comp and Body Scan if you want multi-frequency tracking or ECG readings).

Wyze Scale Ultra (~$50–$120 depending on configuration): A budget-friendly powerhouse featuring Wi-Fi connectivity, a large color screen, and 13 key body composition metrics. It automatically pushes stats to the Wyze app and links up with popular fitness platforms.

Garmin Index S2 (~$200): The absolute best choice if you are already logging your runs, rides, and daily stats in the Garmin ecosystem. It tracks weight, body fat percentage, muscle mass, bone mass, and water weight over Wi-Fi directly into Garmin Connect.

Eufy Smart Scale P3 / P2 Pro (~$50–$90): Anker's Eufy line offers dual Wi-Fi and Bluetooth connectivity, tracking up to 16 metrics (including heart rate) with a clean app interface that supports third-party sync.

Could you tell me which specific health app you use (Apple Health, Google Health Connect, Garmin, Fitbit, etc.) so I can confirm the smoothest direct integration for you?

If you want Wi-Fi syncing + body composition data + integration with a health app, I’d focus on these models:

Withings Body Comp Smart Scale

$229.95

Withings Body Smart Advanced Body Composition Smart Wi‑Fi Scale

$129.99

A few things to check before buying:

• Apple Health user: prioritize Withings; it has one of the strongest Health app integrations.
• Garmin user: get Garmin Index S2.
• Google Fit / Android: Withings and several others support it.
• Body fat and muscle readings are estimates: smart scales use bioelectrical impedance, so they’re most useful for tracking trends rather than treating a single reading as exact.

If you tell me whether you use Apple Health, Google Health Connect, Fitbit, Garmin, or Samsung Health, I can narrow it to the best match.

Here are the best Wi-Fi-enabled smart scales that measure body composition and automatically sync to major health ecosystems (like Apple Health, Google Health Connect/Fitbit, and Garmin) without needing your phone nearby:

Add to listWithings Body Smart — The ideal sweet spot for most users. It measures weight, body fat/muscle percentage, water weight, bone mass, and visceral fat index over Wi-Fi. It features a sharp color screen, automatic multi-user recognition (up to 8 users), and has flawless syncing with the Withings App which bridges directly into Apple Health and Google Fit.

Add to listWithings Body Comp — Step up to this model if you want deeper cardiovascular metrics. Alongside standard body composition, it adds standing heart rate, vascular age, and an electrodermal activity score (assessing sweat gland activity in your feet), syncing seamlessly via Wi-Fi to your preferred health dashboard.

Add to listWyze Scale Ultra — A budget-friendly powerhouse featuring Wi-Fi connectivity (unlike the cheaper Wyze Scale X which is Bluetooth-only). It tracks 13 body composition metrics, presents data on a large 4.3-inch full-color screen, and automatically uploads everything via Wi-Fi to your favorite fitness apps.

Add to listEufy Smart Scale P3 / P2 Pro Go to product viewer dialog for this item. — Excellent for visual progress trackers. These Wi-Fi and Bluetooth scales track up to 16 metrics and use a unique 3D virtual body model/avatar in the EufyLife App to visually map your body composition changes over time. They automatically push data to Apple Health, Google Fit, and Fitbit.

To help narrow down the best choice, tell me:

• Which smartphone health app do you primarily use (Apple Health, Google Health Connect, Fitbit, etc.)?
• Do you have a budget in mind?

If your priority is Wi-Fi syncing + body-composition data + automatic transfer to a health app, I’d narrow it to these:

Withings Body Smart

$129.95

Garmin Index S2

$199.99

eufy Smart Scale P2 Pro

$79.99

RENPHO Smart Scale

$169.99

My top pick: Withings Body Smart

At about $130, the Withings Body Smart is probably the best balance of price, features, and ecosystem compatibility. It measures weight, body fat, water, muscle and bone mass, plus visceral-fat and cardiovascular metrics, and supports Wi-Fi and Bluetooth.

It can feed data into Apple Health and Android Health Connect, so it's a particularly good choice if by "health app" you mean Apple Health or a similar central health dashboard.

Withings Body Smart

$129.95

If you use Garmin

The Garmin Index S2 is the better choice if you already use Garmin Connect. It has Wi-Fi, body-fat %, BMI, skeletal muscle mass and other measurements, with automatic syncing into Garmin's ecosystem. The downside is the roughly $200 price and somewhat narrower health ecosystem.

If you want to spend less

The eufy Smart Scale P2 Pro is around $80 and offers lots of body-composition measurements plus Wi-Fi. It's attractive for the money, although I'd favor Withings if reliable health-app syncing is your primary requirement.

One important caveat: body-fat, muscle, water, etc. from consumer scales are estimates using bioelectrical impedance. They're much more useful for following trends over time than treating any single reading as an accurate measurement.

If you tell me whether you use Apple Health, Google Health Connect, Samsung Health, Fitbit, Garmin Connect, or another app—and your budget—I can pick the exact model I'd buy.
