Quick answer: The best smart scale for Apple Health is the Withings Body Smart, whose Wi-Fi sync writes weight and body composition to HealthKit without opening an app. The Wyze Scale X and Eufy P2 Pro are strong budget picks, and RENPHO is the cheapest reliable option via its Bluetooth app.
Here is the failure mode nobody warns you about: you buy a smart scale, weigh in every morning for a month, and then discover the readings never left the vendor's app. The chart you wanted in Apple Health, feeding your other fitness apps, is sitting in a silo.
Every scale in this roundup avoids that fate. They all write to Apple Health. What separates them is how much friction sits between stepping on the scale and the data landing: Wi-Fi versus Bluetooth, which metrics actually get written, and whether the companion app you are forced to use is any good. Those are the axes this ranking runs on, and the last section covers the part the hardware reviews skip: what your data can do once it is in Health.
This list is about the Apple Health workflow specifically. If you are choosing on raw hardware and measurement quality instead, our smart scale roundup ranks the field on that axis.
| Scale | Sync | Writes to Apple Health | Price |
|---|---|---|---|
| Withings Body Smart | Wi-Fi + Bluetooth | Weight, body fat, lean mass, more | ~$100 to 130 |
| Wyze Scale X | Bluetooth | Weight, body fat, lean mass, more | ~$35 to 50 |
| Eufy Smart Scale P2 Pro | Wi-Fi + Bluetooth | Weight, body fat, more | ~$70 to 80 |
| RENPHO (Elis line) | Bluetooth (most models) | Weight, body fat, lean mass | ~$25 to 35 |
| Etekcity HR (VeSync) | Wi-Fi + Bluetooth (model dependent) | Weight, body fat, more | ~$40 to 55 |
1. Withings Body Smart: Best Apple Health sync, full stop
App: Withings on the iOS App Store, rated about 4.6 stars across roughly 360,000 ratings at the time of writing · Price: commonly listed around $100 to 130
Withings has been the HealthKit reference scale for a decade, and the Body Smart shows why. Wi-Fi sync means the reading uploads the moment you step off; your phone can be in another room, off, or at work. Weight, body fat, lean mass, and a stack of secondary metrics land in Apple Health with no ritual attached.
The companion app is the most polished in the category, handles multiple household users automatically, and Apple sells Withings scales in its own store, which says something about the integration's reliability. The BIA composition numbers carry the same hydration caveats as every scale here.
The Withings app is a full health dashboard, and every measurement it collects can flow into Apple Health.
Best for: anyone who wants the sync to be invisible. Limitations: triple the price of a budget scale for the same weight number; the wider Withings ecosystem is easy to overbuy into. The step-up Body Scan model adds segmental analysis at a much steeper price.
2. Wyze Scale X: Best budget pick
App: Wyze on the iOS App Store, rated about 4.6 stars across roughly 440,000 ratings at the time of writing · Price: commonly listed around $35 to 50
The Scale X is the value anomaly in this list: 13 body metrics, automatic recognition for up to 8 users, and clean Apple Health sync at a price close to a dumb scale. Mainstream testing outlets have repeatedly made it a top overall pick, and its combination of price and feature count is the reason.
The tradeoff is Bluetooth-only sync, so readings reach Apple Health when the Wyze app can talk to the scale, and a companion app that is mostly a smart-home hub. You will scroll past camera feeds to reach your weight chart. The sync itself, once configured, is dependable.
The Scale X reads 13 metrics and hands them to Apple Health through the Wyze app.
Best for: the most metrics per dollar with working Apple Health sync. Limitations: phone-dependent Bluetooth sync; the app serves cameras and vacuums first, scales second.
3. Eufy Smart Scale P2 Pro: Best mid-range option
App: eufy Life on the iOS App Store, rated about 4.8 stars across roughly 17,000 ratings at the time of writing · Price: commonly listed around $70 to 80
The P2 Pro sits in the gap between the budget tier and Withings: Wi-Fi sync like the expensive scales, around 16 measurements, water resistance, and a dedicated fitness app rather than a smart-home hub. Wirecutter has recommended it as a strong alternative pick, and its eufy Life app carries one of the best ratings of any scale companion app.
Wi-Fi matters here for the same reason it does at the top of the list: the sync happens whether or not your phone is nearby, which quietly removes the most common way budget-scale data goes missing.
eufy Life keeps the focus on the scale: weight, BMI, body fat, and a goal tracker, all shareable to Apple Health.
Best for: Wi-Fi sync without the Withings price. Limitations: fewer third-party integrations than Withings; brand ecosystem is smaller in fitness specifically.
4. RENPHO smart scales: Most popular budget option
App: RENPHO Health on the iOS App Store, rated about 4.7 stars across roughly 7,200 ratings at the time of writing · Price: commonly listed around $25 to 35 for the core Elis models
RENPHO owns the budget tier by volume, and the Apple Health handoff is a large part of why the habit sticks: enable Health sharing once in the RENPHO Health app, and weight, body fat, and lean mass flow through on every weigh-in. Most models are Bluetooth-only, so the app needs to be on a nearby phone to catch the reading, which is the main operational difference from the Wi-Fi tier.
We reviewed the scale itself in our Renpho scale review; the short version is that the weight automation is excellent and the composition numbers deserve loose reading. If you feed the readings onward from Apple Health into other apps, our RENPHO setup guide walks the whole chain end to end.
The RENPHO Health app catches each Bluetooth weigh-in and passes weight, body fat, and lean mass to Apple Health.
Best for: the cheapest reliable route into Apple Health weight tracking. Limitations: Bluetooth-only on most models; the extra composition metrics are the loosest estimates in this list. Upgrade paths are covered in best Renpho alternatives.
5. Etekcity HR Smart Fitness Scale: Best on-scale display
App: VeSync on the iOS App Store, rated about 4.8 stars across roughly 74,000 ratings at the time of writing · Price: commonly listed around $40 to 55
Etekcity's HR line earns its spot with a bright color display that shows your weight, body fat, and heart rate on the scale itself, so a quick morning check needs no phone at all. Readings route through the VeSync app, which holds an excellent rating and writes weight, BMI, and body fat to Apple Health.
VeSync is another multi-device platform, covering air fryers and purifiers alongside scales, though its weight tracking screens are genuinely capable. Higher-end models add Wi-Fi; the base models are Bluetooth.
VeSync's weight view: trend, goal line, and unit toggles, syncing onward to Apple Health.
Best for: readable on-scale data and a strong app at a fair price. Limitations: platform app shared with kitchen appliances; Wi-Fi only on the pricier models.
What happens to the data after it lands in Apple Health?
This is the section the hardware reviews leave out, and it is the actual reason to insist on Apple Health sync rather than a vendor silo. Once your weigh-ins live in Health, any app you authorize can read the series, and your scale data starts compounding instead of sitting in a chart you check twice.
For lifters, the useful pairing is weight plus a visual record, since the scale trend cannot tell you where change is happening. GainFrame is our app and one example of that layer: it reads weight, body fat, and lean mass from Apple Health, including readings that arrive from any scale on this list, and lines the trend up against scored progress photos, goal milestones, and rate-of-change tracking. It is iOS only, free to start with a 25-photo lifetime cap, and its photo scores are AI estimates with their own error sources rather than measurements.
Scale data after the sync: milestones, a 90 day trajectory, and weekly rate of change, built from weigh-ins the scale recorded automatically.
The setup ritual is the same for every scale here: open the companion app, find the Apple Health toggle, approve the permission sheet, and confirm the metrics you want shared. Two minutes, once. If a reading ever goes missing, the Health app's Browse tab shows exactly which source wrote what, which makes the sync chain easy to debug.
Buying rule for this category: pay for Wi-Fi if you want the sync to be truly automatic, and pay less if you are fine opening an app at weigh-in time. Every other difference between these scales is smaller than the marketing suggests, because the composition numbers on all of them are estimates from the same BIA physics. The details are in are smart scales accurate, and the worth-it question overall gets a full answer in are smart scales worth it.
Frequently asked questions
What is the best smart scale for Apple Health?
The Withings Body Smart is the most reliable pick: Wi-Fi sync means readings land in Apple Health without opening an app, and Withings has maintained HealthKit support longer than any other scale brand. If you want to spend less, the Wyze Scale X and Eufy P2 Pro sync well at roughly a third of the price.
Can you connect any smart scale to Apple Health?
Most current smart scales can, through their companion app. You enable Apple Health sharing inside the scale's app, approve the permissions, and readings flow into Health from then on. No scale talks to Apple Health directly; the companion app is always the bridge, which is why its quality matters as much as the hardware.
What data do smart scales write to Apple Health?
Weight always, and on most models body fat percentage, lean body mass, and BMI. Some brands also write body water or heart rate where the hardware supports it. Which metrics arrive depends on both the scale and its app permissions, so it is worth checking the Health app's data sources after the first sync.
Do smart scales sync to Apple Health automatically?
Wi-Fi scales do: step on, walk away, and the reading uploads on its own. Bluetooth-only scales, including most RENPHO and budget models, generally need the companion app open or recently active on a nearby phone to receive the reading before passing it to Apple Health. That difference is the main thing extra money buys.
Are the body fat numbers from these scales accurate?
Treat them as rough estimates. Every scale here uses bioelectrical impedance, which commonly disagrees with DEXA by several percentage points and swings with hydration day to day. The weight number is measured directly and is trustworthy. The composition numbers are most useful as a long-run trend rather than absolute values.
