After recognizing the challenges of tracking health metrics manually (inconsistent readings, lack of insights, and limited progress visibility), we set out to find the best smart scales available today.
While professional body composition analysis can be costly and time-consuming (sessions often take 30+ minutes and run over $100 per visit), a high-quality smart scale offers a convenient and affordable alternative—delivering detailed health data right at home.
We rigorously tested more than 20 smart scales, including models from Hume Health, Withings, Fitbit, Garmin, Eufy, Tanita, and others, evaluating them on key factors: accuracy, connectivity, features, ease of use, and value for money.
Below, we break down our top five picks based on real-world testing and in-depth analysis:
When it comes to established smart scale brands, Withings (now Nokia Health) is a household name in health tech.
Upon testing the Body Scan, we were initially skeptical about its £299 price tag. However, we were impressed by its unique medical-grade ECG and vascular age tracking – rare features in consumer smart scales. While it doesn’t match our #1 pick’s clinical-grade body composition accuracy, it offers the most comprehensive heart health insights of any scale we tested.
You can use it with or without WiFi (Bluetooth available), and it features a 18-month battery life – better than most competitors. The included Health+ app subscription provides decent analytics, though not as personalized as Body Pod’s AI coaching.
While Withings carries strong brand recognition, the Body Scan has some notable limitations. Let’s examine the pros and cons:
Medical ECG Function – One of few scales detecting atrial fibrillation
Premium Build – Tempered glass platform with color display
Vascular Age – Unique metric for circulatory health assessment
6-Electrode System – Better than basic 4-point scales
Seamless Integration – Works with Apple Health, Google Fitnutrition/fitness tips.
Overpriced Features – £100 more than Body Pod, despite less accurate body comp
Complex Setup – Requires WiFi configuration for full functionality
Subscription Needed – Advanced analytics require Health+ membership (£9.99/month)
Limited Validation – ECG is FDA-cleared, but body comp lacks clinical certification
Bulky Design – Thicker profile than most competitors
When it comes to affordable smart scales, Renpho has built a loyal following through Amazon with its no-frills approach to body tracking.
During our testing, we were initially skeptical about the £35 price point, but the ES-CS20M delivered surprisingly decent accuracy for basic metrics. While it can't compete with clinical-grade devices like our #1 pick Body Pod, it offers solid performance for casual users who don't need medical-level precision.
The scale connects via Bluetooth to Renpho's straightforward app, which tracks 13 body composition metrics. The plastic construction feels less premium than higher-end models, but makes it lightweight and portable. Battery life lasts about a year with regular use.
The Verdict:
The Renpho ES-CS20M is perfect for casual users who want basic tracking without breaking the bank. However, serious fitness enthusiasts or those needing medical-grade data will want to upgrade to our top pick.
Best for: First-time smart scale buyers or those on a tight budge
Unbeatable Price – Most affordable option we tested
Surprisingly Accurate – For basic weight and BMI tracking
Compact Design – Fits easily in small bathrooms
13 Body Metrics – Includes muscle mass and body water %
User-Friendly App – Simple interface with historical data
Single-Frequency BIA – Less accurate for athletes or obese users
All-Plastic Build – Feels cheap compared to glass-top scales
No WiFi Connectivity – Bluetooth-only can be spotty
Basic Metrics Only – Lacks advanced analysis like visceral fat
No Third-Party Validation – Accuracy not clinically proven
When it comes to stripped-down smart scales that focus purely on fundamentals, Etekcity's affordable model delivers core functionality without the bells and whistles.
During testing, we appreciated its straightforward approach - this scale focuses on weight and BMI measurements without pretending to offer advanced body composition analysis. The large 3.2" LCD display makes readings easy to see, though the 0.5lb margin of error is noticeable compared to more premium scales.
The Verdict:
The Etekcity scale works well as a digital replacement for your old bathroom scale, but doesn't compete with true smart scales for health insights. For users who literally just want to track weight, it gets the job done.
Best for: Families needing multiple user support or those who want basic weight tracking without complexity.
Simple Operation – Step-on design with automatic calibration
Extra Large Display – Clear numbers for easy reading
Budget Price – Often available under £30
Decent Build Quality – Tempered glass platform feels sturdy
Unlimited Users – Great for family use
Limited Metrics – Only measures weight and BMI
No Body Composition – Lacks fat%, muscle mass etc.
Basic Connectivity – Bluetooth-only with occasional sync issues
Accuracy Variance – Can fluctuate ±0.5lb between readings
No App Coaching – Just data tracking without insights
When it comes to balancing aesthetics and functionality, Eufy's P2 makes a strong visual statement with its ultra-thin 0.8" profile and minimalist design.
Our testing revealed this scale performs best as a "gateway" smart scale - it offers more metrics than basic models but falls short of clinical-grade accuracy. The sleek tempered glass platform looks premium, though its measurements showed more variance than our top picks during back-to-back testing.
The Verdict:
The Eufy P2 works well for casual users who prioritize design and want more metrics than a basic scale provides. However, fitness enthusiasts will notice its measurement inconsistencies.
Best for: Style-conscious buyers who want decent metrics in a beautiful package
Sleek, Ultra-Thin Design – Most stylish scale we tested
16 Body Metrics – Includes muscle mass and body water
Baby & Pet Modes – Unique tracking features
Bluetooth 5.0 – Reliable connectivity
User-Friendly App – Clean interface with trend analysis
Inconsistent Accuracy – Varies up to 1.5% between readings
No WiFi Connectivity – Bluetooth-only limits convenience
Shallow Data Insights – Metrics lack depth of analysis
Dated Sensor Tech – Still uses single-frequency BIA
No Third-Party Validation – Accuracy not clinically proven
