More smart scales are now including a handlebar to provide detailed insights into fat and muscle distribution across different parts of the body. The $219.99 Renpho MorphoScan Nova Body Composition Scale follows this trend and goes a step further by integrating a display and simple controls directly into the handle, making it easy to view key measurements at a glance. It measures an impressive 24 body composition metrics, but it's missing some common features, including Wi-Fi support and a pregnancy-safe mode. While it lacks a handlebar and offers fewer advanced insights, the $79.99 Etekcity HR Smart Fitness Scale still provides reliable tracking of essential metrics, so it remains our Editors' Choice winner.
Features: Many Metrics, But No Wi-Fi
The Renpho MorphoScan Nova Body Composition Scale uses dual-frequency Bioelectrical Impedance Analysis (BIA) to calculate the precise makeup of your body during your weigh-in. The MorphoScan has a max weight of 400 pounds and a listed accuracy of 0.2lbs. Its companion Renpho Health app (available for Android and iOS) tracks 50 health metrics, but some (like calories consumed and burned) rely on your input or external sources.
The scale calculates 24 metrics. These include basal metabolic rate (BMR, the minimum necessary energy needed in an inactive state), body fat mass and percentage, body mass index (BMI, a measure of your body weight in relation to your height), body water mass and percentage, fat free mass, metabolic age (which compares BMR to an age-based average), mineral and bone mass and percentage, muscle mass and percentage, protein mass and percentage, skeletal muscle index (SMI, which compares your skeletal muscle with your height to evaluate risk for functional decline), subcutaneous fat (the fat just under your skin), skeletal mass and percentage, visceral fat index (the deeper fat by your organs), waist-to-hip ratio (which compares the approximate circumference of each), and weight. Additionally, it provides evaluative assessments, such as your body type, current weight, and optimal weight.
Going beyond the basics of a typical smart scale, the MorphoScan breaks down segmental muscle and fat for each arm, each leg, and your torso, similar to a dual-energy X-ray absorptiometry (DEXA) scan, which is essentially a medical imagery test to gauge these same attributes. If you want to focus on a particular part of your body for muscle gain, this feature alone could make the MorphoScan worth the premium. According to WebMD, the average cost of a single DEXA scan paid out of pocket is roughly $160 to $175, but other sites put the average closer to $300 per scan.
If you don’t need to know how much muscle or fat is on your trunk and each limb individually, you can save a lot of money with the Etekcity HR Smart Fitness Scale, which uses a similar BIA process to measure its stats, but does not have a handle. It tracks 14 metrics, covering all the basics, including body fat percentage, BMI, subcutaneous and visceral fat, and muscle mass. The Etekcity HR measures your heart rate through your feet, a feature the MorphoScan does not offer.
The MorphoScan is even missing a couple of quality-of-life features present on the Etekcity scale, including a safe mode for pregnant women and pacemaker users that disables the BIA electrical current for weight-only measurements. The Etekcity HR also connects to Wi-Fi and Bluetooth, so you don’t need your phone nearby with the app open to capture data. The $299.95 HumeHealth Body Pod is another smart scale with a handle for DEXA-like insights. It measures 17 metrics in total, including breakdowns of muscle and fat for your arms, legs, and torso, but it also lacks key features like Wi-Fi and a safe mode for pregnancy.
Design: The Handlebar Screen Sets It Apart
Design-wise, the MorphoScan separates itself from the Body Pod with a thicker handlebar featuring a 4.3-inch LCD attached. The display shows basic numbers and color-coded graphics that I found crisp enough to read and easy to understand.
The cylindrical handle has distinct silver electrodes on each side where you need to place your thumbs and fingers during measurement. Above the handle and screen is a small physical control panel that includes a power button, navigation arrows for the display interface, a volume button for the scale’s audible instructions, and a unit button (it supports pounds, kilograms, or stones).
The handlebar attaches to the scale with a retractable thermoplastic polyurethane cord and features a USB-C port on top for charging the scale's 1,000 mAh battery, which promises five months of power between charges.
The scale measures 14.08 by 12.2 by 1.61 inches (LWD), weighs 4.4 pounds, and has a ITO coated glass top. The blue surface features a logo in the center and black lines dividing it into four quadrants, subtly directing where you place your feet.
Setup: Setting Goals and Getting Connected
The MorphoScan scale comes with an instruction manual and a USB-A-to-USB-C charging cable, but no wall brick. The box features a QR code in numerous locations to help you find the app, which is necessary to set up the scale.
To get started, sign in to the app or create an account, and then it’ll ask you a few questions about yourself so it can properly calibrate the data it collects. It asks for your name, birthday, sex assigned at birth (male or female), height, weight, activity level, and then prompts you to set a goal (lose, gain, or maintain weight).
I chose the first option, and it asked me for my current weight again (a strange question to be asked twice by a device meant to measure this very thing). It then asked for my goal weight and how quickly I'd like to reach it. It then showed how much weight I need to lose per week to achieve that goal.
During setup, the app recommended a daily calorie target based on my goal and activity level. It also provided an overview of the various in-app communities of users with similar goals I could join to share my progress. Finally, the app gave me the option to set weigh-in reminders for various times of day and prompted me to turn on notifications.

Next, I turned on the scale by stepping on it briefly. I hit Add Device in the app, and it connected within moments. Once connected, the app offered a brief overview of how to best use the scale and the option to sync with third-party health apps. Renpho integrates with popular fitness apps like Apple Health, Google Fit, and MyFitnessPal.
Using the Scale: Step Up and Hold On
Renpho recommends finding a consistent time of the day to record a weigh-in. To get the best results, it says to step onto the scale with dry, bare feet and to hold the handle away from your body with your arms slightly bent at a 45-degree angle. You’ll need to place your thumbs on the top electrodes and wrap your fingers around the electrodes on the back. You’ll also want to keep your phone nearby with the app open so your data is recorded, as the MorphoScan doesn’t have onboard memory to store a reading locally.
Wake up the scale by tapping it with your foot, then let it calibrate to 0.0 before stepping on. Stand with your feet apart, using the quadrants on the scale as a guide. As the MorphoScan measures and calculates, a voice will pipe up offering guidance and progress reports. It usually finishes measuring within 10 to 15 seconds.
Following a reading, the handlebar display will automatically scroll through multiple data screens, or you can tap the arrows to move forward or back at your own pace. It offers a body composition overview with key stats like weight and fat percentage, along with a chart showing changes in those metrics over time. Other screens show muscle and fat broken down by body part in both a chart and a full-body diagram. You can use the Renpho Health app to see even more details from your measurement, and to check the details of past weigh-ins.
The App: Intuitive and Informational
The main page of the Renpho Health app lets you enter calories you eat or burn if you want weight management guidance. The Me button at the bottom lets you configure device settings, such as language and weight units.
Tap the device at the top of the home screen to pull up the details of your last measurement. You’ll see a full-body diagram front and center, with measurements for fat and muscle in each of your arms, legs, and torso. Below that, it shows your goal status and weight comparison. Scroll further for individual stats, which are color-coded to indicate how they relate to a healthy average.
Tap the down arrow next to any stat to see a description of what it is and where your measurement lies on an average scale. Further down, it shows how your segmental body data compares with a healthy average.
Tap the curved line at the top of the page to see your data charted over time, and use the buttons at the bottom of the chart to change which metric is displayed. The calendar icon in the upper-right corner of this page lets you see past measurements, and you can tap any of them for details.
The app offers an intuitive, easy-to-navigate interface with plenty of details for checking progress and learning about different stats. Finding any one metric in the app is as simple as scrolling. I strongly prefer the Renpho app to the Hume app, which is more colorful but also more cluttered and confusing.
Accuracy: Precise Weight, Imprecise Body Fat
The Renpho MorphoScan Nova proved highly accurate in testing, especially for weight readings. I took one or more daily weigh-ins over a week on the MorphoScan, the HumeHealth Body Pod, the Etekcity HR Smart Scale, and the RunStar 8E SmartScan Ultra (which I’m testing for a future review) to compare their readings.
All four scales stayed within a pound of each other for every measurement, and usually varied by only half a pound. The MorphoScan’s measurements ebbed and flowed from day to day as expected, with my weight dropping the day after a cardio workout and increasing after a weekend of indulgence. On a single day, it responded accordingly when I added or removed clothes. My weight reading went up after I chugged a bottle of water, though my reported water weight stayed the same. The scale even recorded a slight weight increase when I held my 6.8-ounce Google Pixel 7a smartphone.
The MorphoScan’s body fat percentage calculations skewed high compared with both the HumeHealth Body Pod and the Etekcity Smart Scale. The MorphoScan only deviated by 3% to 6% for this metric, so it stayed within a reasonable range, even though it's not quite as precise as the HumeHealth or Etekcity models. Otherwise, the MorphoScan’s measurements for BMI, body water, subcutaneous fat, and visceral fat matched the other two models.
On the DEXA side, the MorphoScan again calculated more fat than the BodyPod, but showed similar muscle mass. I’d imagine the higher fat estimate could be discouraging to some, but the numbers were close enough to HumeHealth's to provide a similar proportional overview. Even with the deviations, the MorphoScan stayed within a reasonably accurate range and provided a meaningful breakdown of my body composition.
