The eufy P3 is the pick for someone who wants the most on-screen and in-app for their money. It packs sixteen BIA metrics, heart rate, and a slick large color display with a 3D virtual-body mode, and — importantly — it has both Wi-Fi and Bluetooth, so it auto-captures weigh-ins like the premium scales while costing far less than the Garmin. It exports to Apple Health, Fitbit, and Google Fit, so your weight flows into whatever you already track. The honest caveat is the one this whole category demands: a longer metric list is more trend indicators, not more truth. Every one of those sixteen numbers derives from the same moderately-accurate bioelectrical-impedance estimate, so read body fat and the rest as direction over time, not as precise figures. It lands at #3 because its accuracy pedigree and trend-app polish sit just behind Withings and Garmin — but on features-per-dollar with real Wi-Fi, it's the standout. Here's the full breakdown.

Read the complete Weight Loss guide →A precise, repeatable weight reading from a highly sensitive ITO-coated sensor, accurate to fine increments — solid enough to make the trend line trustworthy. It sits just below Withings and Garmin on this axis because those brands carry a deeper accuracy pedigree, but in practice the P3's weigh-in is consistent and dependable for tracking progress.
Real Wi-Fi plus Bluetooth means auto-capture with no phone present — the key adherence advantage — and EufyLife draws clear trends and exports to Apple Health, Fitbit, and Google Fit. It scores a touch under the leaders only because Health Mate and Garmin Connect edge it on trend-app polish; the core sync-and-chart job is done well.
The best on this axis by count: 16 BIA measurements including body fat, muscle, water, visceral fat, BMR, metabolic age, and heart rate, on a large color display with a 3D body mode. Framed honestly, more metrics are more trend indicators rather than more absolute truth — but for a buyer who wants the fullest picture to watch over time, this is the deepest set here.
Strong value: real Wi-Fi auto-sync plus the longest metric list and a big display at a fair mid price, well below the Garmin. You get premium-tier connectivity and the most data per dollar, with the only trade-offs being a slightly shallower accuracy pedigree and app polish than the two brands above it.
“Tracks 16 body-composition stats including body fat and heart rate.”
The listing states the P3 tracks 16 stats, including body-fat percentage and heart rate, with a customizable on-screen readout. The count is accurate; the honesty note is that all BIA-derived metrics are trend indicators, not absolute figures.
“Wi-Fi and Bluetooth with auto-sync to EufyLife, Apple Health, Fitbit, and Google Fit.”
The product title and listing confirm both Wi-Fi and Bluetooth, and EufyLife exports to Apple Health, Fitbit, and Google Fit. The Wi-Fi auto-capture is real and is the P3's biggest advantage over the Bluetooth-only value scales.
“Precise weigh-ins from an ITO-coated, sensitive pressure sensor.”
The listing describes a highly sensitive ITO coating and a precise pressure sensor for accurate weigh-ins. Consistent with the scale's solid weight-accuracy score; the weight reading is the metric to trust.
“Your 3D body model and metrics guide your fitness plan.”
The 3D avatar and metric suite are real features, but they're built on BIA body-composition estimates that are reliable-but-rough (Jackson 1988; Siedler 2022) and hydration-sensitive. Useful as motivation and trend-watching; not a precise coaching truth. Marked partial on that honesty.
Most scales at this price are Bluetooth-only; the eufy P3 gives you genuine Wi-Fi auto-capture, so the weigh-in uploads without your phone present and the trend updates by itself every morning. That adherence advantage — the same one the Withings and Garmin charge more for — is the most valuable real-world feature a smart scale can have, and getting it at the P3's mid price alongside the longest metric list is what makes this the features-per-dollar standout.
Sixteen BIA measurements plus a 3D body avatar is the deepest data set here, and for a buyer who likes to watch every dimension of their progress, that's genuinely appealing. But the honest frame this whole page insists on applies squarely to the P3: all sixteen numbers come from the same moderately-accurate BIA estimate, so a longer list is more directions to track, not more truth. Weight is the metric to trust; body fat, muscle, visceral fat, and metabolic age are directions over time under consistent conditions.
The P3's accuracy and trend-app polish are good, not class-leading — which is precisely why it sits at #3 rather than higher. Our top axis is weight accuracy (35%) and the second is app/sync (25%), and on both, Withings' benchmark pedigree and Garmin's precision edge the eufy slightly. That's not a knock on the P3's reliability; it's a reflection that the two scales above it are the accuracy-and-app leaders, and the eufy's win is on breadth and value instead.
EufyLife's 3D virtual-body mode changes as your composition changes, which can make progress feel tangible and keep you weighing in. That's a legitimate adherence aid — consistency is what turns a noisy number into a trustworthy trend. Just keep in mind it's rendered from BIA estimates, so treat it as encouragement rather than a precise readout of your physique. The real progress signal is your weight trend and the direction of body fat over weeks.
The eufy P3 is the standout for a buyer who wants the most on-screen and in-app without paying Garmin money. Sixteen BIA metrics, heart rate, a big color display, a 3D body mode, and — crucially — both Wi-Fi and Bluetooth, so it auto-captures weigh-ins like the premium scales at a fair mid price. It exports to Apple Health, Fitbit, and Google Fit, so your weight flows where you already track. It sits at #3 because its accuracy pedigree and trend-app polish are just behind Withings and Garmin, the two axes that carry the most weight. And the category's honesty note applies fully: a longer metric list is more trend indicators, not more truth — every number comes from the same rough BIA estimate. Weigh under consistent conditions, trust the weight trend, and read body fat as a direction over weeks. For features-per-dollar with real Wi-Fi, this is the one to buy.

Across 15 BIA devices vs a 4-compartment reference, body-fat constant error ranged ~−3.5% to +11.7%, yet select devices tracked CHANGE acceptably. Supports reading each of the P3's metrics as a trend, not an absolute. (Evidence about BIA accuracy, not a manufacturer claim.)
