A smart scale does far more than tell you your weight. It syncs to your phone, tracks body fat and muscle over time, and turns a daily step-on into a real picture of your progress. But the body-composition numbers are only as trustworthy as the technology behind them. We analyzed thousands of verified buyer reviews, recent sales data, and expert evaluations to find seven smart scales that track the right things and actually sync without a fight.

Our Best Overall pick: the handle-free MorphoScan Base brings the same 8-electrode segmental sensing as the pricier Nova into a stand-on-only design at a lower price.
An 8-electrode dual-frequency scale with a retractable handle and its own 4.3-inch color screen, giving hand-to-foot segmental readings for arms, legs and trunk without opening an app.
A dual-frequency 8-electrode scale with a multi-point measurement handle, giving segmental hand-to-foot readings on top of the 50-plus metrics unlocked in the arboleaf app.
The arboleaf Smart Scale with BMI, Body Fat, Muscle Mass, 50+ Body Metrics packs 8-electrode segmental sensing, the same core technology as our Best Overall and Best for Body Composition picks, into a stand-on-only design priced well below either. It costs a bit more than our Best Affordable pick, but that scale is a simpler 4-electrode model without segmental arm and leg readings.
An 8-electrode scale with a retractable handle that adds hand-to-foot segmental readings and heart rate tracking, shown on a 4.3-inch full-color display without ever opening the app. Reviewers say it matches pricier segmental scales' core measurement capability at a fraction of the cost.
Our Best for Body Composition pick: an 8-electrode, dual-frequency scale with its own TFT handle display, tracking 50-plus metrics across a 5-segment breakdown of arms, legs and trunk. Wi-Fi syncing sends every reading straight to the VeSync app and onward to Apple Health, Google Fit, Fitbit or Samsung Health.
Our Best Affordable pick: a tempered-glass, 13-metric BIA scale at the lowest price in this lineup, syncing to the VeSync app and Apple Health, Google Fit, Fitbit and Samsung Health - reviewers highlight its durable build and simple setup as an easy on-ramp to body-composition tracking.
Short on time? These three cover most buyers: our Best Overall segmental scale, the best value pick at the lowest price in this lineup, and the most detailed pick for full body-composition tracking.
Understand the category before you buy - what the science actually says, and which specs matter.
Every smart scale promises body fat, muscle mass, and a dozen other readings, but the way they measure and how honest those numbers are can vary a lot. Here is how they work, how much you should trust the body-fat percentage, and the features actually worth comparing.
A smart scale measures your weight, then sends a tiny, harmless electrical current up through your body to estimate what that weight is made of. Fat, muscle, and water conduct that current differently, so the scale uses the reading to estimate body fat, muscle mass, body water, bone mass, and more. It then syncs everything to an app over Bluetooth so you can watch the trends instead of guessing from a single number.
That technique is called bioelectrical impedance analysis, or BIA, and every scale in this lineup uses it. The metrics range from 13 on the simpler models up to 50-plus on the premium RENPHO with a retractable handle, which adds segmental breakdowns for each arm, each leg, and your trunk.
This is the part worth understanding before you trust any reading. BIA is an estimate, not a lab measurement, and two things decide how good that estimate is.
The first is how many electrodes the scale uses. A 4-electrode scale reads only foot-to-foot, sending current up one leg and down the other, so it mostly measures your lower body and estimates the rest. An 8-electrode scale adds hand contact, either through a handle or grips, and measures your arms and trunk directly. If body composition matters to you and not just weight, the 8-electrode models here, including the FITINDEX and the handled RENPHO, will read your upper body far more faithfully.
The second is you. BIA readings swing with hydration, meals, exercise, and time of day, so the absolute body-fat percentage from any consumer scale can differ by several points from a clinical DEXA scan. The fix is simple: weigh yourself under the same conditions every time, ideally first thing in the morning with an empty stomach and bare feet, and trust the trend line rather than any single day's number.
Once you know how the measurement works, a few features decide which scale fits you:

Our Best Overall pick. The MorphoScan Base brings RENPHO's 8-electrode segmental technology, the same core sensing that makes the Nova stand out, into a simpler, handle-free scale with a bright color LED display and automatic recognition for different household members. Tom's Guide and Cybernews both credit it with a genuinely first-rate metric range, including uncommon readings like skeletal muscle and protein mass, at well under the Nova's price. The main knock from reviewers is on the software side: some found contradictory or thin health guidance inside the app, so treat the numbers as data to track rather than medical advice.
The MorphoScan Nova is RENPHO's flagship, and expert coverage from outlets including Live Science and MedGrade consistently calls out its segmental accuracy as a step above standard stand-on scales. The retractable handle carries the dual-frequency BIA circuit through your arms as well as your legs and trunk, and its own 4.3-inch color display shows the full readout on the spot, no phone required. A USB-C rechargeable battery is rated for months of use per charge, and the RENPHO Health app tracks over 50 metrics with no subscription paywall. Reviewers' main caveat: at roughly three to four times the price of a typical stand-on smart scale, and with occasionally temperamental app connectivity, it's a premium buy rather than an easy default.
The CS10K pairs arboleaf's 8-electrode dual-frequency BIA with a multi-point measurement handle, so it reads the arms and trunk directly through hand contact instead of estimating them from the feet alone, the same segmental approach used by the pricier handle-equipped scales elsewhere in this comparison. A 7-in-1 on-scale display surfaces the most-checked numbers immediately, while the arboleaf app unlocks the full 50-plus metric set, including segmental fat and muscle balance, fat-free mass, protein level and body type, along with family profiles and trend charts. The platform is rated to 400 pounds and runs on alkaline batteries rather than a rechargeable pack. arboleaf backs it with a 1-year warranty through retailers, extendable to 2 years with a direct purchase from arboleaf.com. As a newer addition to this lineup, it doesn't yet carry the same independent professional-review history as some of the more established scales here.
The arboleaf Smart Scale with BMI, Body Fat, Muscle Mass, 50+ Body Metrics uses 8-electrode dual-frequency bioelectrical impedance to estimate body composition from a stand-on-only platform, no handle required. Seven core readings, including weight, BMI, body fat, muscle mass, body water, bone mass, and visceral fat, display directly on the scale, while the companion arboleaf app unlocks 50+ metrics in total, including segmental breakdowns for the left arm, right arm, and legs. The 12.2 x 12.2 inch tempered glass platform is sized for stability, and the scale runs on three included AAA batteries rather than a rechargeable pack. Bluetooth syncing pushes results into the arboleaf app, which can forward data to Apple Health, Google Fit, and Fitbit. It sits below the handle-equipped arboleaf CS10K in this lineup, trading arm-isolated readings for a lower price. As with any bioelectrical-impedance scale, body fat and muscle mass figures are estimates that shift with hydration and time of day rather than clinical-grade measurements.
The Scale Ultra BodyScan is Wyze's entry into segmental body composition tracking: a retractable handle adds electrodes to the ones already in the platform, so the scale reads your arms, legs and trunk individually instead of estimating the upper body from your feet alone. Reviewers at BGR and HomeAndTome describe it as matching the core measurement capability of premium segmental scales costing several times more, while its 4.3-inch full-color TFT display shows the full 13-metric readout, including heart rate, body fat, muscle mass and visceral fat, directly on the handle with no phone required. It connects over both Wi-Fi and Bluetooth to the Wyze app, and Wyze rates the four AAA batteries for up to eight months of use per set. The tradeoff testers point to is build quality: the plastic housing keeps the price down but doesn't have the heft of costlier handle-equipped rivals, and at least one reviewer would have preferred a rechargeable battery over AAA cells.
Our Best for Body Composition pick. Etekcity built its reputation on the simpler 4-electrode scale that Forbes Vetted named a best-bathroom-scale pick for its accuracy and value, and this WiFi model pushes that formula further with a full 8-electrode, dual-frequency layout and a retractable handle with its own TFT display. Independent accuracy testing from SmartBuyLabs generally finds 8-electrode designs land in the 3-6 percent body-fat variance range against clinical methods, tighter than the 5-8 percent typical of foot-only 4-electrode scales, because the hand contacts measure the arms and trunk directly instead of estimating them from the legs. The result here is a 50-plus-metric, 5-segment readout, separate figures for both arms, both legs and the trunk, synced over Wi-Fi to the VeSync app and onward to Apple Health, Google Fit, Fitbit or Samsung Health. A USB-C rechargeable battery, multi-user recognition, a phone-free Guest Mode and a Baby Mode for tracking a child's weight round out the feature set, and the 440 lb platform is among the highest capacities in this lineup. As a newer, more premium listing than Etekcity's long-established 4-electrode models, it has not yet built up the same independent-review history, so treat the segmental numbers as a trend to track rather than a clinically validated figure.
Our Best Affordable pick. Reviewers at outlets like Hashimashi and The Body Blueprint consistently point to this Etekcity as an easy on-ramp to body-composition tracking: 13 straightforward readings, a 6mm tempered-glass platform and four precision sensors reading in 0.2 lb increments, all synced through the VeSync app to Apple Health, Google Fit, Fitbit and Samsung Health. Its durability and simple setup are frequently praised as friendly to first-time users, and at the lowest price in this lineup, FSA/HSA eligibility helps lower the effective cost even further. The tradeoffs testers note are minor: the full metric set requires bare feet and the app (the standalone display only shows weight), it runs on replaceable AAA batteries rather than USB-C, and a minority of buyers report occasional Bluetooth pairing hiccups.
