A bathroom scale used to do one thing: display your weight. Smart scales add Bluetooth or Wi-Fi connectivity, an app, multiple-user profiles, and estimates such as body-fat percentage, muscle mass, water percentage, and body-mass index. That extra information can make it easier to see long-term trends instead of focusing on a single number.
The important word is trends. Smart scales are useful for consistent weigh-ins, but their body-composition estimates are not the same as clinical measurements. Hydration, meals, exercise, time of day, foot contact, and device algorithms can all change the result. The best model is not the one that promises the most metrics; it is the one that gives you repeatable weight readings and an app you will actually use.
For this guide, we focused on smart scales available through Amazon US and prioritized affordable, recognizable models. Wirecutter named the Wyze Scale X its top pick at about US$40, while Tom’s Guide also highlights Wyze as its budget option and recommends Withings Body Smart, Withings Body Scan 2, and Renpho models for different buyers. Prices and stock can change, so check the exact Amazon listing before buying.

1- Wyze Scale X: The “Best Overall Value” Pick
The Wyze Scale X is the most balanced choice for shoppers who want a smart scale without turning a basic weigh-in into a complicated health dashboard. Wirecutter named it the best smart scale and listed it at approximately US$40 from Amazon.
Why we like it: Wirecutter reports that the Scale X provides consistently accurate readings, accommodates up to eight users, and connects through Bluetooth to a relatively simple app. The scale uses four AAA batteries, which the publication says lasted about 22 months in its testing.
That combination is appealing because a smart scale should reduce friction, not add another maintenance project. Multiple household members can use the same scale, and the app can show weight history in a format that is easier to interpret than a collection of handwritten numbers. The scale also includes modes for measuring items such as pets or luggage, which can be useful even if you do not care about every body-composition metric.
Keep in mind: Bluetooth is convenient, but it is not the same as Wi-Fi. Your phone generally needs to be nearby for readings to synchronize, and the scale is not the best choice if you want automatic cloud syncing without opening an app. Wyze’s ecosystem and privacy history may also matter to buyers who are especially cautious about connected-home products.
Wirecutter notes that the Wyze Scale X is the model to choose when reliable weight tracking and a straightforward app matter more than an extensive health platform.
Best for: Families and individuals who want an affordable smart scale with reliable weight trends and a clean, uncomplicated app.
2- RENPHO Smart Body Fat Scale: The “Best Budget” Option
The RENPHO Smart Body Fat Scale is one of the most popular entry points into smart scales because it combines a low price with a long list of advertised measurements. The Amazon listing describes weight, BMI, body fat, 13 metrics, a 400-pound capacity, Bluetooth, and synchronization with fitness apps.
Why we like it: RENPHO gives budget shoppers more data than a basic digital scale without requiring a premium purchase. The app can be useful for tracking weight over time, and the higher capacity makes it suitable for a wider range of household users. Bluetooth connectivity keeps the hardware inexpensive while still allowing readings to be recorded on a phone.
The scale is also easy to understand as a purchase. If you want a connected scale for occasional weigh-ins, a lower-cost model makes more sense than paying for Wi-Fi, ECG-style features, or an expensive subscription. Its broad compatibility with fitness applications can also make it easier to keep weight data alongside activity information.
Keep in mind: The large number of metrics can make the product look more precise than it really is. Body-fat percentage, muscle mass, water percentage, and similar results are estimates based on bioelectrical impedance and algorithms. Use the same scale under similar conditions and focus on long-term movement rather than treating a single reading as a diagnosis.
App permissions and integrations can change, so check the current RENPHO app description and privacy policy before connecting it to other services. Also confirm the exact model because RENPHO sells several scales with similar names and different metric lists.
Best for: First-time smart-scale buyers who want many app-based metrics at the lowest practical price.
3- Greater Goods Verve: The “Wyze Alternative”
The Greater Goods Verve is a sensible alternative when the Wyze Scale X is unavailable or when you prefer a simpler health accessory from a company that focuses on wellness products. Wirecutter specifically identifies the Verve as a comparable model worth considering if its top pick cannot be found.
Why we like it: The Verve offers the essential smart-scale experience: weigh yourself, send the reading to an app, and observe changes over time. That is enough for many users, and a less crowded interface can be more useful than a dashboard filled with numbers you never check.
It is also a good reminder that app experience matters as much as the glass platform or display. If the app is confusing, unreliable, or difficult to sync, the scale becomes an ordinary bathroom scale with extra setup. Greater Goods is therefore worth considering for buyers who want an accessible alternative rather than the absolute cheapest anonymous marketplace model.
Keep in mind: The Verve may not offer the same level of ecosystem integrations or user familiarity as Wyze, Withings, Garmin, or RENPHO. Confirm the current app support, number of profiles, measurement list, and phone compatibility before buying.
As with any smart scale, do not select it solely because the product page advertises more body-composition measurements. Consistent weight tracking and an app that fits your routine are more important for most shoppers.
Best for: Buyers seeking a straightforward Wyze alternative with app-based tracking and a wellness-focused brand.
4- Withings Body Smart: The “Best App Experience” Choice
The Withings Body Smart is designed for buyers who want a more polished health-tracking ecosystem and are willing to pay more than the budget models. Tom’s Guide names it its best overall smart scale and highlights its attractive, easy-to-navigate app.
Why we like it: Withings has built a broader health platform around its connected devices, so the Body Smart makes sense for users who want weight readings to live alongside other wellness data. The app experience is a major part of the value: graphs, profiles, and history are easier to use when the software feels designed rather than added as an afterthought.
A more established ecosystem can also be helpful for users who already own other Withings products or want to share readings across supported health services. The scale is a better fit for people who see smart weighing as part of a long-term tracking routine rather than a one-time gadget purchase.
Keep in mind: The Body Smart usually costs more than the Wyze or RENPHO options, and the extra software features may not matter if you only want to see your weight. Some features or metrics may also depend on region, account settings, app version, or subscription terms, so check the current product page carefully.
Do not assume that an attractive app makes its body-fat estimate medically accurate. Its main advantage is organization, consistency, and convenience.
Best for: Users who value a polished app, broader health-data organization, and a more established smart-scale ecosystem.
5- Garmin Index S2: The “Best for Garmin Users” Scale
The Garmin Index S2 is the natural choice for people who already use Garmin watches, cycling computers, or the Garmin Connect platform. Tom’s Guide includes it among the smart scales it tested, and its primary appeal is integration with the Garmin ecosystem rather than low price.
Why we like it: For an existing Garmin user, a scale that sends weight and related readings into Garmin Connect can reduce the need to manage another app. The scale is also designed for multiple users and offers the kind of connected measurement history that fitness-focused buyers expect.
The ecosystem benefit is important here. A smart scale is most useful when its data appears where you already review training, activity, and health trends. Garmin users may prefer that convenience even if a cheaper Bluetooth scale offers similar basic measurements.
Keep in mind: The Index S2 is typically more expensive than the budget models in this guide. It is difficult to justify if you do not use Garmin products, and you should confirm current compatibility with your account, phone, and Garmin Connect version before buying.
Like every consumer body-composition scale, it should not be used to diagnose a medical condition or replace professional assessment. Its strongest selling point is ecosystem integration, not clinical measurement.
Best for: Garmin users who want weight data connected to Garmin Connect and their existing fitness-tracking routine.
What to Look For Before You Buy
Weight consistency: The most important feature is repeatable weight measurement. A smart scale that gives slightly different readings every time is less useful than a basic model that consistently tracks the trend. Place the scale on a hard, level floor and weigh under similar conditions.
Bluetooth versus Wi-Fi: Bluetooth models are usually cheaper and use your phone to synchronize readings. Wi-Fi models can upload data automatically, but they may cost more and require a home-network setup. Choose Bluetooth if you are comfortable opening the app near the scale; choose Wi-Fi for more passive syncing.
App quality: Read recent app reviews and check the required permissions. Look for clear graphs, multiple-user support, export options, and integration with the health platform you already use. An app update can change the experience, so do not rely only on an old product review.
Body-composition metrics: Smart scales may estimate body fat, muscle mass, water, visceral fat, bone mass, and BMI. These numbers can be useful as rough trends under consistent conditions, but they are not clinical measurements. More metrics do not automatically mean more accuracy.
Maximum capacity: Check the listed weight limit before ordering. The RENPHO model discussed here advertises a 400-pound capacity, but other versions may have different limits. Do not assume that every scale from the same brand supports the same maximum weight.
Power source: Some scales use AAA or other replaceable batteries, while others use rechargeable batteries. Replaceable batteries are convenient if you do not want another device to charge. Rechargeable models can reduce battery purchases but require a cable and charging routine.
Household profiles: If several people will use the scale, look for explicit support for multiple profiles and reliable automatic recognition. Some scales can confuse users with similar weights, so confirm that the app allows manual correction.
Privacy and data control: A smart scale can collect weight and health-related information. Review the app’s privacy policy, account requirements, export options, and data-sharing settings before connecting it to Apple Health, Google Fit, Garmin Connect, or another service.
Medical considerations: Body-composition scales commonly use bioelectrical impedance analysis. If you have a pacemaker, implanted medical device, are pregnant, or have been told to avoid BIA devices, follow the manufacturer’s warning and ask a qualified healthcare professional before using the composition features. The ordinary weight function may have different guidance, but the product manual should take priority.
Frequently Asked Questions
Are smart scales accurate?
Most reputable smart scales can provide useful and reasonably consistent weight readings when placed on a hard, level surface. Body-fat and other composition measurements are estimates that can vary with hydration, food, exercise, foot contact, and time of day. Use them for trends, not diagnosis.
Do smart scales work without Wi-Fi?
Many Bluetooth smart scales work without Wi-Fi. They store or send the reading to a phone through Bluetooth when the app is open or nearby. Wi-Fi models can synchronize more automatically but may require a network connection and account setup.
Can multiple people use one smart scale?
Yes. Many smart scales support multiple user profiles, and the Wyze Scale X is described by Wirecutter as accommodating up to eight users. Automatic recognition is not perfect, especially when two people have similar weights, so check the app before assuming every reading was assigned correctly.
Can I use a smart scale if I have a pacemaker?
Some smart scales warn against using bioelectrical impedance features with implanted medical devices. Read the exact product manual and follow the manufacturer’s safety guidance. If you are uncertain, ask your healthcare professional before using the composition-measurement function.
Do smart scales require a subscription?
The basic weighing function usually does not require a subscription, but some brands may place advanced metrics, coaching, or historical features behind an account or paid plan. Check the current app and product terms before buying if avoiding subscriptions matters to you.
What is the best affordable smart scale in 2026?
The Wyze Scale X is the strongest overall value because Wirecutter rates it highly and lists it near US$40. The RENPHO Smart Body Fat Scale is a good budget alternative when you want many app-based metrics, while the Greater Goods Verve is a sensible fallback if Wyze is unavailable.
Should I buy a smart scale or a regular digital scale?
Choose a smart scale if you want automatic history, multiple users, app integration, or trend graphs. A regular digital scale is better if you only want a weight reading, prefer not to create an account, or do not want health data stored in an app.
