Let’s face it: stepping on a scale isn’t usually the highlight of anyone’s morning routine. But what if your scale did more than just deliver that number? What if it greeted you with trend graphs, heart rate data, body composition insights—and maybe even a smiley face?

Welcome to the world of smart scales: sleek little platforms of truth that now double as fitness coaches, data analysts, and self-esteem rollercoasters. Whether you're tracking fat, muscle, water, your dog’s weight (yes, really), or just want something shiny that talks to your phone—there’s a smart scale for you.

We put five of the most popular options on the market side by side—no judgment, just data. Scroll on to see which scale is the right fit for your lifestyle (and your bathroom tiles).

Withings Body+ Smart Scale

★★★★★ (4.2/5)
Our Thoughts (click to read)

After spending time with the Withings Body Smart scale, we’re genuinely impressed by how much it offers beyond just tracking weight. It’s clear that this scale was designed with real-life use in mind — from the multi-user recognition and family-friendly modes to the subtle touches like the Eyes-Closed display. The automatic Wi-Fi syncing makes it feel truly “smart,” and the detailed health metrics help you understand your body in a more holistic way. Overall, it’s a sleek, reliable, and insight-packed scale that fits effortlessly into a modern wellness routine.

Feature Details
Metrics Measured Weight, BMI, body fat, muscle mass, bone mass, water %, visceral fat, BMR, metabolic age, heart rate
Integration  Wi-Fi & Bluetooth; Health Mate app, Apple Health, Google Fit, more
Battery Life Up to 15 months (4× AAA batteries)
User Profiles  Up to 8 users (auto recognition); modes: Athlete, Pregnancy, Baby, Eyes-Closed 
Special Features  Color LCD, Position Control™, AutoSync, Withings+ support

Pros

  • The Eyes-Closed Mode eases anxiety.
    Sometimes we just don’t want to see the number. This feature lets you weigh in without stressing — the data still goes to the app, just not on the screen.

  • It uploads everything automatically, even if your phone is in another room, you don't have to do a thing.

Could Improve

  • Uses disposable AAA batteries instead of USB charging, which can feel a bit dated, however you can't complain about 15 month battery life!

Runstar Scale

★★★★★ (4.7/5)
Our Thoughts (click to read)

The Runstar Scale punches well above its price—8-electrode measurements, a clear on-scale readout, smooth app syncing, USB-C charging, and support for up to 24 users make it genuinely practical. We’d love Wi-Fi and a slightly cleaner app, but for tracking trends and getting rich body data, it’s excellent value.

Feature Details
Metrics Measured Weight, BMI, body fat, muscle mass, bone mass, water %, visceral fat, BMR, metabolic age, heart rate, etc. (~22 metrics)
Integration  Bluetooth; StarFit app; syncs with Apple Health, Google Fit, Fitbit
Battery Life USB‑C rechargeable; lasts ~90 days per charge
User Profiles Up to 24 users; auto-recognition
Special Features  8-electrode BIA, color display, real-time metric readout, Athlete & Pregnancy modes, FSA/HSA eligible

Pros

  • Pairing with the app takes under a minute, and syncing with Apple Health or Google Fit is seamless.

  • The bright display shows multiple metrics right after weighing in, plus motivational icons to keep you engaged.

Could Improve

  • We noticed the scale can wobble a bit when stepping off unevenly, so watch your step!

Garmin Index S2

★★★★★ (4.0/5)
Our Thoughts (click to read)

The Garmin Index S2 stands out as one of the most polished smart scales available. Its sleek design, sharp colour display, and seamless Wi-Fi syncing make daily tracking genuinely enjoyable. The weight trend graph is a particularly useful touch, and for Garmin users, the integration with Garmin Connect couldn’t be smoother. While it comes at a higher price point, the scale delivers reliable performance, effortless usability, and a premium feel that makes it well worth the investment—especially if you’re already in the Garmin ecosystem.

Feature Details
Metrics Measured Weight, BMI, body fat %, skeletal muscle mass, bone mass, body water %, and 30‑day weight trend graph 
Integration   Wi‑Fi sync to Garmin Connect (via app); compatible with Apple Health, Google Fit through Garmin integrations
Battery Life Up to 9 months using 4× AAA batteries (included) 
User Profiles Supports up to 16 user profiles; automatic user recognition based on weight 
Special Features Full‑color display with customizable widgets, weight‑trend graph, weather widget on scale, BLE/ANT support 

Pros

  • If you're already using Garmin products, the Index S2 is a natural extension—automatic Wi‑Fi sync to Garmin Connect ties body metrics directly into your existing health and fitness ecosystem

  • Multiple users confirm that its weight measurement is extremely consistent, often within 0.2 lbs compared to commercial gym scales

Could Improve

  • While it sits at the higher end around ÂŁ130, its reliable accuracy and smooth user experience make it worth the investment

Wyze Smart Scale

★★★★★ (4.6/5)
Our Thoughts (click to read)

The Wyze Smart Scale is a standout in its price range. It’s sleek, easy to use, and packed with features you wouldn’t expect—like Pet and Luggage modes. Syncing is fast, and the app keeps tracking simple. While it lacks Wi-Fi and deep health insights, it nails the essentials with surprising accuracy and polish. For everyday wellness tracking, it’s a smart, budget-friendly choice

Feature Details
Metrics Measured Weight, BMI, body fat %, lean body mass, water weight, heart rate + 8 additional metrics (12 total) 
Integration  Bluetooth sync via Wyze app; compatible with Apple Health, Google Fit, Health Connect (& more) 
Battery Life Uses included batteries (likely AAA), though the specific lifespan isn’t stated 
User Profiles Automatically recognizes up to 8 users; supports guest mode for shared use 
Special Features Sleek modern design, clear LED display, FSA/HSA eligibility in some regions, easy daily use 

Pros

  • Beyond basic body tracking, the Wyze Scale includes niche features like Pet Mode and Luggage Mode, which let you weigh animals or suitcases by subtracting your own weight.

  • The setup takes less than a minute, and the app interface is minimal but responsive. The scale also automatically recognizes users by weight, which avoids constant profile-switching.

Could Improve

  • While Bluetooth works great, the lack of Wi-Fi means you must open the app every time you weigh yourself to sync data. Users who travel or weigh in at different times of day find this limiting

The Etekcity Smart Scale really overdelivers for its price. It tracks all the essentials (and then some), looks great in the bathroom, and ditches the hassle of batteries with a rechargeable setup.

Sure, body fat numbers can bounce around a bit—but for keeping tabs on your overall health, it’s a smart, stylish little sidekick.

Special Features

  • Despite its low cost, users praise the tempered glass design, sleek LED display, and solid build quality—calling it surprisingly polished for its price point

Could Improve

  • As with other bioelectrical impedance scales, readings like body fat or muscle percentage can shift based on hydration or time of day—users note occasional unexpected changes
