Best Smart Scales
Top 5 for weight and body fat
Our #1 pick is the Withings Body Smart. A smart scale logs your weight and body fat to an app, so you can see the trend instead of one number. We compared 5 popular smart scales on Amazon, from a budget starter to a Garmin with 16 profiles.
How we picked: we shortlist by Amazon Best Seller rank and number of ratings, then compare published specs. We don't test these products hands-on.

The short answer
For most people, the Withings Body Smart is the smart scale to buy. The listing says it was developed with hospitals and clinically validated, tracks weight to within 50 g, adds body composition and a heart rate reading at every weigh-in, and syncs over Wi-Fi and Bluetooth. It is also listed as Apple Health compatible, which is the first thing many shoppers check. It costs more than a basic scale, but it is the safest all-round buy.
If you want more body detail for less money, the Wyze Scale BodyScan with Handle is our value pick. You hold a built-in handle, and its 8 electrodes estimate fat and muscle in each arm, each leg and your torso. If you just want a starter scale, the RENPHO Elis 1 is the best budget choice and one of the best-known smart scales on Amazon. The Wyze Scale Ultra sits in the middle with Wi-Fi and a big color screen, and the Garmin Index S2 is the pick if your watch already lives in Garmin Connect.
Skip the Withings if you only want to see your weight and do not care about body fat or trends, because a plain digital scale does that for a fraction of the price. Skip the handle-style scales if you share a small bathroom with little storage. And skip any smart scale if you have a pacemaker or another implanted medical device: these scales send a tiny electrical current through your body, and makers warn against using them in that case. Ask your doctor first.
How we picked: we compared popular smart scales sold on Amazon, read each product listing’s spec sheet and what owners report about the apps, syncing and day-to-day use, then ranked them side by side. We do not test scales hands-on, and every “on paper” claim below comes from the listing. Body fat numbers from any home scale are estimates, so judge them by the trend, not by one reading.

Why each one made the list
What each pick does best, where it falls short, and the typical Amazon price when we checked.
- 1. Best Overall
Withings Body Smart
BeastScore 93 / 100Typically $120–$140 on Amazon (checked October 21, 2026)The Body Smart is the smart scale that gets the basics right. The listing says it was developed with leading hospitals, is clinically validated and tracks weight to within 50 g, which matters most when you watch a slow trend. It adds body fat and muscle analysis and a heart rate reading at every weigh-in, all on a color display that shows your trend. It connects over Wi-Fi and Bluetooth, so your phone does not need to be nearby, and the title calls it Apple Health compatible. The trade-offs: it costs about five times a budget scale, and it measures through your feet only, so it cannot split fat and muscle by arm or leg.
Pros- Clinically validated and tracks weight to within 50 g, per the listing
- Wi-Fi sync with an Apple Health-compatible app
- Heart rate and body composition on every weigh-in
Cons- Costs several times more than a budget smart scale
- Foot-only measurement, so no arm and leg breakdown
- Costs more than the Wi-Fi Wyze Scale Ultra, which has a bigger screen
- 2. Best for Body Composition
Wyze Scale BodyScan with Handle
BeastScore 91 / 100Typically $70–$90 on Amazon (checked October 21, 2026)This is the cheapest way to get body composition that goes beyond one fat percentage. The listing says you grip a built-in handle while you stand, so 8 electrodes can estimate fat and muscle across your arms, legs and torso. The Wyze app shows 44 metrics, and the 4.7-inch screen shows seven key numbers without opening the phone. It syncs with Apple Health, Health Connect and Fitbit, remembers up to eight app users and has a guest mode. A baby, pet and luggage mode is a handy extra. The limits: segment numbers from any home scale are estimates, it uses Bluetooth only, and the handle makes it bulkier to store than a flat scale.
Pros- 8 electrodes and a handle for arm, leg and torso estimates
- 44 metrics in the app, with Apple Health and Fitbit sync
- Costs less than the Withings, with far more body detail
Cons- Bluetooth only, with no Wi-Fi sync
- The handle makes it bulkier to store
- Segment numbers are estimates, so watch the trend
- 3. Best Budget Pick
RENPHO Elis 1
BeastScore 88 / 100Typically $20–$30 on Amazon (checked October 21, 2026)The Elis 1 is the easy way to try a smart scale. The listing says it has 4 electrodes, measures 13 body metrics, shows weight, BMI and body fat on the display, and sends the rest to the RENPHO Health app over Bluetooth. It syncs with Apple Health, Samsung Health and Fitbit, supports unlimited users, measures in 0.2 lb steps and handles up to 400 lbs on tempered glass. It is among the most popular smart scales on Amazon, which tells you how many households start here. The catch is that cheap body fat numbers are the least reliable. Use it to watch your weight trend and treat body fat as a rough guide.
Pros- The lowest price of any scale here
- 13 metrics, unlimited users and Apple Health sync
- Tempered glass with a 400 lb capacity
Cons- Only 4 electrodes, so body fat is a rough estimate
- The display shows just 3 metrics
- Bluetooth only, so you need your phone nearby
- 4. Best for Garmin Users
Garmin Index S2
BeastScore 86 / 100Typically $180–$210 on Amazon (checked October 21, 2026)If you already wear a Garmin watch, the Index S2 puts your weight and body composition in the same Garmin Connect account as your runs and sleep. The listing says it measures weight, weight trend, body fat percentage, BMI and skeletal muscle mass, plus bone mass and body water. It syncs over Wi-Fi, supports up to 16 user profiles and runs up to nine months on four AAA batteries. The listing calls it a sleek design with a high-resolution color display. The downside is price: it costs the most here, and it only makes sense inside the Garmin ecosystem. Without Garmin Connect, a Withings gives you more for less.
Pros- Weight and body composition land in Garmin Connect
- Up to 16 profiles for a large household
- Battery life up to 9 months on 4 AAA batteries
Cons- The most expensive scale here
- Best only if you already use Garmin Connect
- Foot-only measurement, so no arm and leg breakdown
- 5. Best Mid-Price Wi-Fi Scale
Wyze Scale Ultra
BeastScore 84 / 100Typically $40–$60 on Amazon (checked October 21, 2026)The Wyze Scale Ultra is the middle step between a budget starter scale and a Withings. The listing highlights an extra-large 4.3-inch color display you can customize in the app, Wi-Fi and Bluetooth so your weigh-in syncs even when your phone is in another room, and 13 body metrics including heart rate, which shows only in the Wyze app. Data goes to Apple Health, Health Connect and Fitbit, and it is FSA and HSA eligible. The trade-offs: it measures through the feet only, so there is no arm and leg detail, and Wyze’s handle-style BodyScan gives you more body detail for a bit more money.
Pros- Wi-Fi and Bluetooth sync at a mid-range price
- Large 4.3-inch color display with customizable metrics
- Syncs with Apple Health, Health Connect and Fitbit
Cons- Foot-only body composition, so no segment data
- Heart rate shows only in the Wyze app
- The Wyze BodyScan gives more detail for a little more

Quick tips before you buy
Soft floors and bathmats throw off the readings. Put the scale on tile or wood, and keep it in the same spot every day.
Water in your body shifts through the day. A morning weigh-in after the bathroom and before breakfast gives the most steady trend.
The scale is only half the product. Make sure its app syncs with Apple Health, Health Connect or Garmin Connect, whichever you already use.
Body fat scales send a small electrical current through your body. Makers warn against using them with a pacemaker, another implanted device or during pregnancy. Ask your doctor first.
Quick answers
What is the best smart scale?+
For most people it is the Withings Body Smart. It is clinically validated per the listing, tracks weight to within 50 g, adds body composition and heart rate, and syncs over Wi-Fi. The Wyze Scale BodyScan with Handle is the better value if you want more body detail, and the RENPHO Elis 1 is the best budget pick.
Are smart scales accurate for body fat?+
They are good at showing change over time and weaker at the exact number. Home scales estimate body fat by sending a small current through your body, and results shift with hydration, food and the time of day. DEXA is the standard for exact body fat. Weigh in under the same conditions and watch the trend.
What is the best smart scale for body composition?+
The Wyze Scale BodyScan with Handle gives the most detail for the money. Its 8 electrodes and handle estimate fat and muscle in each arm, leg and torso, with 44 metrics in the app. The Withings Body Smart is the better pick if you care more about weight accuracy and a polished app than about segment data.
What is the best smart scale for Apple Health?+
The Withings Body Smart is listed as Apple Health compatible. The RENPHO Elis 1 and both Wyze scales also list Apple Health sync. The Garmin Index S2 is built around Garmin Connect, so check the Garmin app’s sharing options before you buy if Apple Health is a must.
Do I need a Wi-Fi smart scale, or is Bluetooth enough?+
Bluetooth is enough if you keep your phone nearby when you weigh in, because the scale sends the reading to the app on the spot. Wi-Fi saves each weigh-in to the cloud without your phone, which is handy for families. The Withings Body Smart, Wyze Scale Ultra and Garmin Index S2 support Wi-Fi.
Are smart scales safe with a pacemaker?+
Not without asking your doctor. Body fat scales pass a tiny electrical current through your body, and the makers advise against using them with a pacemaker or another implanted medical device. They also advise against use during pregnancy. If that applies to you, use a plain digital scale instead.
Is a smart scale worth it over a regular scale?+
Yes if you want trends, body fat and an app that logs every weigh-in for you. A smart scale also supports several users on one device. No if you only want a number. A plain digital scale is cheaper and shows your weight just as well.
