I’ve always been a little suspicious of smart scales. They promise to measure everything from your body fat to your metabolic age, but I’ve often wondered—can a piece of glass and metal really tell me that much about myself? So, I decided to find out. I tested eight of the most popular smart scales on the market, and let’s just say… some of them surprised me.
1. Withings Body Scan
The Withings Body Scan immediately felt like the overachiever of the group. It’s sleek, futuristic, and even comes with a handle that looks like something from a sci-fi medical lab.
This scale doesn’t just weigh you—it reads your full body composition, measures segmental fat, and even performs a mini ECG.
What impressed me most was the precision. My readings didn’t fluctuate wildly between weigh-ins, and the health data synced seamlessly with the app.
The scale felt like a personal trainer and doctor rolled into one. Even its app interface made me want to actually check my stats instead of ignoring them.
The only downside? The price. It’s definitely the “luxury sedan” of smart scales. But if accuracy and insight are your goals, this is the one that truly delivered next-level performance.
2. Garmin Index S2
Garmin knows athletes, and the Index S2 definitely caters to that crowd. It felt like a fitness coach in scale form—data-heavy, precise, and a bit intimidating at first glance.
Connecting it to my Garmin app was seamless, and it automatically logged weight, BMI, and body composition data alongside my workouts.
I loved that the scale’s color screen displayed all the essentials without forcing me to pull out my phone every time. And as someone who runs, cycles, and sometimes forgets to stretch, it was nice seeing how my weight correlated with my training weeks.
That said, this isn’t a casual-user scale. It’s built for people who already live in the Garmin ecosystem. If you’re a data nerd who wants to see how hydration and sleep impact your stats, this one’s worth every penny.
3. Eufy Smart Scale P3
The Eufy Smart Scale P3 was the surprise underdog of the bunch. It’s affordable, unassuming, and doesn’t make a big fuss—but it performs remarkably well. Setup took less than two minutes, and the readings were consistent every single day.
The EufyLife app is clean, simple, and intuitive. I appreciated how it gave me just the right amount of information—body fat percentage, muscle mass, bone density—without drowning me in graphs. For a midrange scale, it felt like getting premium features at a smart price.
The only hiccup was that it sometimes took two or three tries to sync with my phone. But for under $100, I can’t really complain. The P3 earns serious points for dependability and ease of use.
4. Wyze Scale X
Wyze has a reputation for making budget-friendly tech that punches above its weight, and the Wyze Scale X fits that description perfectly. It’s sleek, minimal, and the app is surprisingly robust for something so affordable.
I liked that it measured 13 metrics, including heart rate, and allowed me to switch between users easily. The readings were fairly stable, and the app integrated smoothly with Apple Health and Google Fit. It made tracking progress feel effortless—no overthinking required.
However, if you’re serious about ultra-accurate body composition data, it’s not quite there. Still, for everyday users who just want motivation to stay on track, the Wyze Scale X delivers outstanding value.
5. Renpho Smart Scale
Renpho is practically the household name in smart scales, and for good reason. The Renpho Elis series proves you don’t need to spend a fortune to get solid performance.
Setup was quick, the Bluetooth connection worked like a charm, and the app gave me 13 health metrics in seconds.
What stood out was consistency. Even after multiple weigh-ins at different times of day, the readings didn’t swing dramatically. It’s also incredibly portable—light enough to move around and durable enough for daily use.
Sure, the design feels basic compared to pricier competitors, but it does what it promises—no fluff, no fuss. It’s the “Honda Civic” of smart scales: reliable, efficient, and surprisingly capable.
6. InBody H20N
If data is your love language, the InBody H20N will absolutely speak to you. This scale doesn’t just estimate body fat—it uses bioelectrical impedance to analyze muscle distribution, water retention, and fat percentages in specific body segments.
It helps you count your calories better than ever.
The app displays data in detailed graphs that make you feel like you’re reviewing a lab report. I found it fascinating to see how muscle mass in each leg changed after a tough leg-day session. It gave me a much clearer understanding of my body’s composition and progress.
That said, the InBody H20N isn’t for everyone. It’s expensive, and the app takes some getting used to. But if you’re the type who loves precision and progress tracking, this one delivers unmatched depth.
7. Withings Body Smart
The Withings Body Smart felt like the perfect middle ground between sophistication and simplicity. It looks just as sleek as the Body Scan but comes at a friendlier price point—and still delivers outstanding performance.
It tracks weight, fat mass, muscle mass, and visceral fat, and it automatically detects who’s stepping on it.
I especially liked the “Eyes Closed” mode, which lets you weigh in without seeing the number immediately—perfect for those trying to focus on long-term trends rather than daily fluctuations.
Everything about it just works. It’s reliable, accurate, and elegant without being intimidating. For most people, this is the ideal balance of practicality and smart features.
8. QardioBase X
The QardioBase X felt like it was designed for people who want both brains and beauty. It’s sleek, circular, and looks more like a design piece than a bathroom gadget. The app connects quickly and gives detailed insights into your weight, BMI, and muscle mass.
I appreciated how Qardio added motivational feedback—little smiley faces that react to your progress. It sounds gimmicky, but it actually made me look forward to stepping on it.
Plus, the rechargeable battery is a big win for anyone tired of swapping out AAA batteries every few months.
However, it occasionally lagged when syncing, and the readings fluctuated slightly day to day. It’s not perfect, but it’s one of the most user-friendly smart scales I tested—and it definitely earns points for style.
