Wyze Scale Ultra BodyScan Review: 13 Metrics, One Step
Eight electrodes, a built-in handle and a 4.3-inch colour screen. I stood on it, pulled the handle, and watched it break my arms, legs and torso out separately - then went through every number the app gave back.

THE VERDICT
A normal bathroom scale answers one question and it is the least useful one. This answers thirteen, and the handle is the reason - without electrodes in your hands it cannot read your upper body at all, so arms and torso are guesswork on a foot-only scale. If you are tracking a change rather than a number, that distinction is the whole point. It syncs over Wi-Fi without your phone nearby, recognises up to eight people, and there is no subscription attached to any of it.
A bathroom scale gives you one number, and it is the number that tells you the least. Weight moves with how much water you are holding, what you ate last night, and the time of day. It does not tell you whether the last three months of work built anything.
That is the gap this Wyze Scale Ultra BodyScan review is about. It reads 13 body metrics in a single step, and crucially it reads your upper body too - which a scale you only stand on physically cannot do.
Why the handle matters more than the spec sheet suggests
There are eight smart electrodes here. Four sit in the base under your feet, and four are in a built-in handle you lift and hold. That split is the entire design argument.
A foot-only scale sends its current up one leg and down the other. Everything above your waist is inferred. Put electrodes in both hands as well and the current has a path through your torso and arms, so the scale measures those segments instead of estimating them. Wyze calls the result segmental analysis: arms, legs and torso reported individually rather than rolled into one figure.
Without electrodes in your hands, a scale is guessing about everything above your waist.
Wyze puts numbers on how close that gets to a clinical scan: a correlation of 0.98 or better against DEXA for body fat mass, and 0.99 or better for lean mass. Those are the brand's own figures from the campaign brief rather than something I measured, but they are the claim the design is built around.
The 13 metrics
The full list, as Wyze publishes it:
✦ Weight
✦ Body fat percentage
✦ Lean body mass
✦ BMI
✦ Muscle mass
✦ Muscle mass percentage
✦ Visceral fat
✦ Basal metabolic rate
✦ Bone mass
✦ Metabolic age
✦ Protein
✦ Body water percentage
✦ Heart rate, shown in the app
Taking a reading
Bare feet, which matters - socks break the circuit and you will not get a body composition reading at all. Step on, let it settle on weight, then lift the handle out and rest your thumbs on the sensors with your fingers wrapped around the bar.
The scale sends a small current through you and the display walks through the progress. Mine showed the prompt to place my thumbs, then a percentage counting up while it worked. It is a stand-still-and-wait job, not a step-and-go one, and the display tells you when it is done.
The 4.3-inch screen is full colour and customisable, so the readings you care about are on the scale itself rather than only in the app. Cycling through, it shows steps, incline, speed, distance and calories on the fitness side, and your weight and composition on the body side.
The app, and the part that is actually useful
The headline screen gives you weight, BMI, body fat percentage and muscle mass. Scroll down and you reach Body Segment Data, which is where the handle earns its place: a body diagram with a figure against each limb, left and right reported separately, and a Muscle and Fat toggle to switch which set you are looking at.
Seeing left arm and right arm as two different numbers is a different experience from seeing one muscle-mass figure. It is the difference between a number and a map.
Below that is Trends & History, which plots weight over time, and a detailed report covering lean mass, visceral fat, BMR, metabolic age and skeletal muscle. That report exports as a PDF, which is the format you would want if you were handing it to anyone.
There is also a calorie-burn panel that estimates what different activities would burn for your body - slow walk, brisk walk, jogging, yoga, cycling, basketball, swimming, stair climbing, mountain hiking. Treat those as estimates rather than measurements, but as a way of choosing between a walk and a bike ride it is a reasonable nudge.
Living with it
It syncs over both Wi-Fi and Bluetooth 5.0, and the Wi-Fi part is the one that changes the daily experience: readings upload without your phone nearby. You weigh yourself and the data is already there when you next open the app. No sync button, no standing on a cold tile waiting for a handshake.
Four AAA batteries are in the box and Wyze rates them at up to eight months. It recognises up to eight people automatically and takes unlimited guests on top, so a household is not fighting over whose reading is whose. It syncs to Apple Health, Health Connect and Fitbit - not Samsung Health, which is worth knowing before you buy if that is your ecosystem.
It is FSA and HSA eligible, which is unusual for a scale and genuinely useful if you have funds to spend. There are also Baby, Pet and Luggage modes, which do what they sound like.

Who it is for
If you want to know what you weigh, any scale does that and this one is overkill. If you are three months into something and you want to know whether what you lost was fat or muscle, and whether your left side is keeping up with your right, this answers a question the cheap scale cannot reach - and it does it in about the time it takes to stand still and breathe.
