Withings has been making medical-grade health hardware for over a decade, and the Body Comp is their most comprehensive scale yet. It measures 14 metrics including weight, BMI, body fat %, muscle mass, bone mass, water percentage, visceral fat index, and — uniquely — nerve health via electrodermal activity sensors. That last one is a surprisingly useful early indicator of metabolic health that no competitor at this price level offers. The Health Mate app is best-in-class: clean, trend-focused, and genuinely useful over months of data.

The segmental body composition (measuring each limb and your torso separately) gives you accuracy that consumer-grade scales rarely achieve. At $200 it’s the most expensive pick on this list, but it’s also the closest thing to a clinical body composition analyzer you can buy for your bathroom. Supports up to 8 users, integrates with Apple Health, Google Fit, and over 100 health apps, and the glass platform is genuinely beautiful on any bathroom floor.

If you wear a Garmin watch, the Index S2 is the obvious companion. Everything syncs directly to Garmin Connect — no third-party bridges, no manual exports — and your weight and body comp data sits right alongside your activity history, sleep scores, and HRV trends in one unified dashboard. The integration is seamlessly tight in a way that Garmin’s ecosystem does better than almost anyone. You step on the scale, it knows who you are, and the data is in Garmin Connect before you’ve finished your morning coffee.

The S2 measures 13 metrics including weight, BMI, body fat %, skeletal muscle mass, bone mass, and body water %, with support for up to 16 users. The color LCD display is a nice touch over the basic LED displays you get from budget competitors. It also integrates with Apple Health and MyFitnessPal. The $150 price is well-justified for anyone already in the Garmin ecosystem; for everyone else, Withings or Eufy offer better value.

The Withings Body+ is the sweet spot in Withings’ lineup: you get the class-leading Health Mate app, rock-solid connectivity, and Withings’ renowned accuracy — at exactly half the price of the Body Comp. You lose the segmental analysis and nerve health metrics, but you keep the five most important ones: weight, body fat %, muscle mass, bone mass, and water percentage. For most people tracking general fitness progress, that’s genuinely all you need.

The setup is effortless — connect to WiFi (2.4GHz), step on, done. The scale auto-recognizes up to 8 users and the Health Mate app’s trend charts and weather-style indicators (“Your weight is trending down this month”) make it easy to stay motivated. It syncs to Apple Health, Google Fit, and Fitbit. At $100, it’s the recommendation for anyone who wants Withings quality without paying flagship prices.

If you have multiple people in the house who all want to track their health data separately, the Eufy P3 solves the family problem better than anything else at this price. It supports 16 user profiles with auto-recognition, tracks 16 body composition metrics, and uses both Bluetooth and WiFi so it syncs whether you’re standing on it with your phone nearby or not. The EufyLife app is genuinely good — not as polished as Withings Health Mate, but solid enough for daily use.

At $80 with 16 metrics and 16 user profiles, it punches considerably above its price class. It includes a 3D body model in the app that visually shows where you’re carrying fat and muscle, which kids and teens find particularly engaging for staying motivated. It integrates with Apple Health, Google Fit, and Fitbit. The main limitation is accuracy — it’s good but not Withings-level — but for a family of four all trying to stay on track together, it’s the best tool at the price.

Qardio built the Base 2 specifically for Apple users, and it shows. The iOS integration is the deepest of any scale on this list — every measurement drops instantly into Apple Health with proper categorization, HealthKit integration works flawlessly, and the Qardio app itself follows Apple’s design language so closely it feels like a first-party tool. If you live in the Apple ecosystem and want weight and body comp data feeding cleanly into your Health app dashboard, this is the one.

It measures five metrics (weight, BMI, body fat %, muscle mass, water), supports unlimited user profiles via the app (each steps on and the scale auto-identifies them), and has a beautifully minimal design with no visible display — all data goes straight to your phone. The $130 price is fair for the build quality and ecosystem depth, though you’re paying a premium for the Apple-centric experience rather than metric count.

Athletes and gym-goers have different priorities than casual health trackers — they care about muscle mass trends, body fat percentage at specific training phases, and hydration levels after workouts. The Etekcity Smart Fitness Scale addresses these with 13 metrics and a VeSync app that displays workout-relevant data prominently rather than burying it under a general wellness dashboard. The scale is specifically calibrated to be more accurate for athletic body compositions (lower body fat, higher muscle mass) where cheap BIA sensors often struggle.

At $50 it’s a remarkable value for the feature set. The VeSync app integrates with Apple Health, Google Fit, and Fitbit, and you can track up to 8 users. The tempered glass platform handles up to 400 lbs and the measurement resolution is 0.1 lb / 0.05 kg — precise enough to track meaningful changes week over week. For serious fitness tracking without spending Garmin or Withings money, this is your pick.

The Fitbit Aria Air is a focused, no-frills scale for Fitbit users who want their weight data living in the same place as their step counts and sleep scores. The Fitbit app integration is seamless — weight trends appear right in your dashboard alongside all your other health data, and the Weekly Report includes weight as part of your overall wellness summary. For anyone who’s already bought into the Fitbit ecosystem with a tracker or watch, adding the Aria Air is the natural next step.

It only measures three metrics (weight, BMI, and body fat % via connected Bluetooth) which is lean compared to competitors at the same price. It also lacks WiFi — you need your phone nearby for syncing. But the Fitbit app’s excellent long-term trending and coaching features more than compensate for the hardware simplicity. It also syncs to Apple Health and Google Fit for non-Fitbit-exclusive data sharing.

The Renpho Smart Scale is the best-selling body composition scale on Amazon for a reason: it costs $30 and measures 13 metrics. Thirteen. At thirty dollars. That is the entire pitch. The Renpho app is straightforward, the Bluetooth pairing works reliably, it supports unlimited user profiles, and it syncs to Apple Health, Google Fit, and Samsung Health. For someone who’s never tracked body composition before and wants to start without committing to a premium device, this is the perfect entry point.

The tradeoffs are real but predictable: the BIA sensors are less accurate than premium brands (especially for athletes or people with very high/low body fat), the app is functional but not beautiful, and there’s no WiFi. But for $30 — roughly the price of a large pizza — you get a tool that will genuinely change how you track your health. Over 200,000 Amazon reviews averaging 4.7 stars doesn’t lie.
