The best smart scales in 2026
Updated Aug 30, 2026 · prices dated per offer
A smart scale's real job is turning a single weigh-in into a trend line, and the four picks below split into four different ways of doing that: a Wi-Fi flagship, a scale built around one brand's fitness ecosystem, a twenty-five dollar Bluetooth scale that skips every subscription, and a budget pick built to feed whatever fitness app you already use.
None of these are medical devices. Body fat, muscle mass and the other body composition numbers come from bioelectrical impedance, a small electrical current run through your feet, and every brand here estimates rather than measures those figures. Every price below was checked on the date shown.

Best premium
1. Withings Body Smart
The Body Smart is the most complete scale here: Wi-Fi sync uploads a weigh-in without a phone nearby, its Position Control sensor checks foot placement to reduce reading errors, and it tracks a wider metric set than most rivals, including a Visceral Fat Index and heart rate at every weigh-in.
We found it at Best Buy for $109.95, marked down from a $129.95 comparable value, price checked 2026-08-30. The core scale and its Health Mate app are free to use; an optional Withings+ membership, listed on the Health Mate app's App Store page at $9.99 a month or $99.99 a year, adds extra coaching but is not required for the scale's basic readings.
Skip it if: you just want a weight and body fat trend line as cheaply as possible, since the RENPHO Elis 1 tracks similar core metrics for a quarter of the price.
Best for the Garmin ecosystem
2. Garmin Index S2
If you already wear a Garmin watch or ride with a Garmin bike computer, the Index S2 is the only scale here that puts your weight and body composition data in the same Garmin Connect app and feed as your training data, with Wi-Fi sync and up to 16 user profiles for a large household.
We verified it at $199.99 both at Target and at Best Buy, price checked 2026-08-30. Garmin Connect is free, so there is no subscription to add on top, but the star rating trails the rest of this roundup and several buyers report Wi-Fi setup issues, so it is worth owning mainly for the ecosystem tie-in rather than the hardware alone.
Skip it if: you don't already use Garmin Connect, since you are paying roughly double the Withings Body Smart's price for an ecosystem benefit you won't use.
Best budget
3. RENPHO Elis 1
The Elis 1 tracks 13 body composition metrics over Bluetooth for $24.99, RENPHO's long-running bestseller and the cheapest legitimate smart scale in this roundup by a wide margin. There is no subscription of any kind; the RENPHO Health app and full metric history are free.
We verified the $24.99 price at both Target and RENPHO's own store, price checked 2026-08-30, with the store backing it up: 8,136 ratings at Target and 10,457 at RENPHO's site, both averaging around 4.9 out of 5.
Skip it if: you want Wi-Fi sync without a nearby phone, or native Apple Health integration out of the box; it is Bluetooth-only and syncs through RENPHO's own app.
Best for pairing with other apps
4. Wyze Scale S
The Scale S is built to stay out of the way of whatever fitness app you already use: it syncs with Apple Health, Google Fit and Fitbit in addition to the Wyze app, so your weight data lands wherever your other tracking already lives instead of being locked into one ecosystem.
We verified it at $29.98 directly on wyze.com, price checked 2026-08-30; it was not listed on Target or Best Buy as of this writing. All 12 tracked metrics are free in the Wyze app, and buying direct from wyze.com extends the standard 1-year warranty to 18 months.
Skip it if: you want Wi-Fi sync or the option to buy from a retail store rather than wyze.com directly.
Common questions
Which of these scales has no subscription?
The RENPHO Elis 1 and Wyze Scale S both work fully with no recurring fee. The Garmin Index S2's Garmin Connect app is also free. Only the Withings Body Smart has an optional paid tier, Withings+, and even there the core scale readings work without subscribing.
Do any of these need Wi-Fi to work?
No, all four work over Bluetooth at minimum. The Withings Body Smart and Garmin Index S2 add Wi-Fi, which uploads a reading automatically without a phone nearby; the RENPHO Elis 1 and Wyze Scale S are Bluetooth-only, so their paired app needs to be open or the phone needs to be in range to sync.
How accurate is the body fat percentage on these scales?
All four estimate it with bioelectrical impedance, not a clinical measurement, so treat the number as a trend to watch over weeks rather than a precise reading. Expect it to shift with hydration, food and time of day on every scale in this roundup, including the more expensive ones.
Which scale is best for a shared household?
The Garmin Index S2 supports the most user profiles at up to 16, followed by the Withings Body Smart at up to 8 and the Wyze Scale S also at up to 8. RENPHO says the Elis 1 supports unlimited profiles with automatic recognition, though very similar body weights between household members can occasionally get cross-logged on any of these scales.
