Wyze Scale X
Low-cost Bluetooth smart scale with 13 body metrics and a weight-only mode, $38.98

The verdict
Wyze Scale X is a $38.98 Bluetooth scale that shows weight and body fat on its display and sends 13 metrics to the Wyze app. It suits you if you want cheap tracking and a weight-only setting that Wyze says switches the current off. The catch: Wyze gives no accuracy figure that names it, and an independent test of a Wyze Scale read body fat high on average. Look at the Withings Body Smart for Wi-Fi sync or the Renpho Elis 1 for a lower list price.
The trade-off
Wyze gives no accuracy figure that names the Scale X, and only weight and body fat show on the scale while the app holds the rest.

A GOOD FIT FOR
You want a low-cost scale that tracks weight trends and sends body readings to the Wyze app.
- You want a low-cost scale that tracks weight and sends body readings to the Wyze app
- You want a weight-only setting that Wyze says switches the current off, such as for a pacemaker or pregnancy
- You want your readings to sync to Apple Health, Fitbit or Health Connect
- You want baby, pet and luggage modes for weighing things you hold
THINK TWICE IF
- You wear a pacemaker and want body-fat readings: Wyze says the current may affect a pacemaker, so you'd use the weight-only mode
- You want fat and muscle readings for each arm and leg, which Wyze doesn't list for the Scale X
- You need body-fat accuracy that an independent study has confirmed for this model
- Your floor is carpeted, since Wyze says carpet affects calibration
What still needs checking
- Accuracy of the Scale X's weight and body composition readings: Wyze gives no figure, and no study naming the Scale X was found
- Which Wyze Scale model the 2023 study tested
- Whether the Wyze app or any scale feature ever needs a paid plan
- What replacement AAA batteries cost, since Wyze doesn't price them
- Shipping cost for a single scale
Is the Wyze Scale X accurate?
Wyze gives no accuracy figure that names the Scale X, and its FAQ says readings may differ from those of professional-grade instruments1.
Wyze’s accuracy page for “Wyze Scale” claims weight within ±0.5% and impedance data within ±1% of a full-scale reading5. That page names no model, so it may not cover the Scale X.
In a 2023 lab study of 73 healthy adults, a Wyze Scale read body fat 3.6 percentage points high on average against a four-compartment model7. The paper gives no model number, so it may not be the Scale X7.
Can you use the Wyze Scale X with a pacemaker?
Wyze says the current may affect a pacemaker, but you can use the scale if you turn on weight-only mode, which disables the current1.
For pregnancy, there are no known risks with the current, but results may not be accurate, and Wyze advises consulting your physician first1.
Does the Wyze Scale X need a subscription?
Wyze lists no subscription, but it doesn’t say whether the app ever charges1.
The scale pairs with the Wyze app over Bluetooth, and Wyze lists syncing to Apple Health, Fitbit and Health Connect1. The page prices only the scale itself, at $38.9812.
The practical details.
| Exact variant | Wyze Scale X, black or white, Classic or Butterfly sensor pattern (same price), four AAA batteries included |
|---|---|
| Body composition method | Bioelectrical impedance through 4 electrodes in the glass surface. The Wyze app shows 13 metrics: weight, body fat %, heart rate, lean body mass, BMI, muscle mass, muscle mass %, visceral fat, basal metabolic rate, bone mass, metabolic age, protein and body water %. Only weight and body fat show on the scale |
| Weighing | Four independent leg sensors. Range 11 to 400 lb (5 to 180 kg). Units: lb and kg |
| Heart rate | Measured in the Wyze app in under 10 seconds, according to Wyze. The scale's display shows only weight and body fat |
| Users, ages and modes | Up to 8 users, told apart by weight: they must differ by more than 13.2 lb with the app closed, or 6.6 lb with it open. Body composition appears for ages 10 to 100. Baby, pet, luggage and pregnancy modes, plus a weight-only mode that switches the current off |
| Connectivity and app | Bluetooth 5.0 (BLE), with a range of up to 32 ft in Wyze's testing. The scale stores readings and syncs when you open the Wyze app. Needs iOS 12 or Android 7.0 or later, and syncs with Apple Health, Fitbit and Health Connect. Wyze's spec list names no other connection |
| Battery | Four 1.5 V AAA batteries, included. Wyze says up to 22 months of battery life |
| Display and operating range | LED display for weight and body fat. Operating temperature 41°F to 104°F (5°C to 40°C), storage -4°F to 131°F |
| Use guidance | Bare feet on both electrodes for body composition. With socks or shoes on, the scale measures weight only. Damp feet are fine, but wet feet may affect accuracy. Wyze says carpets and rugs can affect calibration |
| In the box | Wyze Scale X, four AAA batteries and a quick start guide |
| Dimensions | 11.8 x 11.8 x 1.18 in and 3.96 lb (1.80 kg), per Wyze's tech specs and its comparison table. |
| Materials | Tempered glass with an ITO (indium tin oxide) coating. Wyze describes the glass surface as the electrodes. It lists an IPX3 water rating and names no frame or base material. |

Change the assumptions to fit your use. Leave an unknown cost blank. Add water, subscriptions, cleaning, shipping and taxes if they apply. Use average operating power, not the maximum rating.
3-year known subtotal
$38.98Incomplete: annual consumables, other annual costs, energy use. This is not the full ownership cost.
Energy component: Unknown
Purchase + installation + years × (annual consumables + annual other) + watts/1000 × hours/day × 365 × years × $/kWh. Annualized allowances, not an exact replacement schedule. Excludes taxes, shipping, finance and resale unless entered.Replacement parts & cost assumptions
Recorded recurring parts and refills:
- AAA batteries (four): price not stated, every 22 months. Wyze includes the first set and says up to 22 months of battery life. It doesn't price replacements.
- Purchase is the $38.98 list price on Oct 23, 2026, before tax. The $6 Wyze Week offer the page advertises isn't counted.
- Other annual costs are unknown. Wyze lists no subscription, but it doesn't say whether the app ever charges.
- Annual consumables are unknown. The box has four AAA batteries that Wyze says can last up to 22 months, but Wyze doesn't price replacements. The scale is battery-powered, so energy use isn't counted.
Evidence & sources.
Are smart scales worth it? Our evidence review grades the research as Moderate. That grade is about the claim, not about this product.
- Manufacturer claimPrice, specs, modes, battery life, connectivity and use guidance come from Wyze's US product page. Return terms and the warranty come from Wyze's return policy and limited warranty terms, effective June 12, 2026.14 Manufacturer information, not independent testing. The product page and the policy differ on the warranty. The spec list says 1-year. The policy says 18 months for purchases from Wyze on or after Jan 1, 2026.
- Manufacturer claimWyze's FAQ says the Scale X uses bioelectrical impedance to estimate body composition, and results may differ from professional-grade instruments or methods. The current may affect a pacemaker. Wyze says the scale can be used with a pacemaker or in pregnancy if weight-only mode is on, which disables the current. For pregnancy, Wyze says there are no known risks with the current, but results may not be accurate. It advises consulting a physician first.1 This is Wyze's own guidance, not a clinical finding.
- Manufacturer claimWyze's accuracy page for "Wyze Scale" says it reports weight within ±0.5% of a full-scale reading, and bioelectrical impedance data within ±1%. It also says incorrect setup details make the measurements incorrect.5 The page names no model, so it may not cover the Scale X. It doesn't say how the figures were tested. A percentage of full-scale reading isn't the same as the body-fat error a person would see.
- Published studyA 2023 laboratory study of 73 healthy adults aged 19 to 50 compared 15 body-fat devices with a four-compartment reference model. A Wyze Scale read an average of 3.6 percentage points high (95% CI 2.2 to 5.0). Its total error against the reference model was 6.9 points. The paper rated its standard error of the estimate "poor".7 The paper names the device "Wyze Scale" with no model number, so it may not be the Scale X. A separate RENPHO scale and a Withings Body Cardio were also in the study.
- Regulator recordFDA's openFDA 510(k) data returned no record with Wyze as applicant or in a device name. Wyze's Scale X page claims no FDA clearance.168 A database search isn't proof that no listing exists. Wyze's pacemaker and pregnancy guidance is its own, not a regulator's.
