The top 5 at a glance
A smart scale weighs you, then sends a tiny electrical signal through your bare feet to estimate body fat, muscle and water, and passes the readings to a phone app over Bluetooth. Most measure through the feet alone; scales with a handle add electrodes for the hands, for a fuller reading. Some show only your weight and leave the rest to the app; others put several readings on the display.
Treat the body-fat and muscle figures as estimates, best read as a trend: weigh at the same time of day and compare week to week. Every scale here passes its readings to Apple Health, Samsung Health and Google Fit, on iPhone or Android. Makers advise anyone with a pacemaker or another implanted device to check before using the body-fat readings, and some scales have a weight-only mode for that.
What matters
- Unlimited user profiles, if the whole household will use it.
- A weight limit with room to spare, and a roomy platform.
- A baby mode, for weighing a baby or pet in your arms.
#1RENPHO Elis 1 Smart Scale
$30–$50
A slim glass scale that shows your weight and sends 13 readings, from BMI to muscle mass and a body-fat estimate, to the Renpho Health app, which passes them on to Apple Health, Samsung Health or Fitbit. It keeps readings when the phone isn’t nearby and syncs them later, so there’s nothing to open first thing in the morning.
What owners say: Setting up the app is easy and the scale is simple to live with, owners say, and many find its readings accurate, which is what counts when they’re tracking toward a goal.
A closer look: There’s a Renpho app for Apple Watch too (not the original Series 1). Take care with the glass corners: Renpho warns against knocking them into the tub or a wall, so it’s best set down well away from both.

#2Etekcity ESF-551 Smart Scale
$20–$30
The extra-large, bright display is easy to read from standing, and Baby mode lets you hold a baby or the cat while it takes your own weight away. It reads in fine 0.02 kg (0.05 lb) steps and tracks 13 measurements in its app, which passes them on to Apple Health, Samsung Health, Google Fit, Fitbit or MyFitnessPal.
What owners say: Accurate, simple and easy to read, owners say, with an app that sets up on the phone in minutes and works well. Durability gets a mixed verdict.
A closer look: Everyone in the house can have a profile, as the app takes unlimited users. Zero-Current mode is there for anyone who only wants a weight and BMI, with no signal sent through the feet, and Etekcity suggests it for anyone with a pacemaker.
- Weight-only mode for pacemaker wearers

#3RENPHO Elis 2X Smart Scale with Large Display (R-A018)
$50–$75
Skip the app for a quick check: step on and the large display shows weight, body fat, muscle mass, water, bone mass, BMI and metabolic age, with the full 13 readings and the long-term trends in the Renpho Health app. The glass top has an ITO coating that RENPHO says sharpens accuracy, on a compact 28 cm (11 in) square.
What owners say: Owners like how it looks, how easy it is and how clearly the display reads, and its small footprint suits a cramped bathroom. Battery life lets some of them down, and opinions on accuracy vary.
A closer look: Athlete mode, chosen in the app, is there for anyone who trains hard, and the pet and baby modes weigh a dog or a baby held in your arms. With battery life the usual complaint, a spare set of AAAs in the bathroom cabinet saves a blank screen one morning.
- Glass coated for accuracy
- Metabolic age on the screen

#4GE CS10H 8-Electrode Smart Scale with Handle Display
$100–$150
Pull up the handle and eight electrodes read through your hands as well as your feet, for a fuller picture than a feet-only scale, with more than 50 readings in the Fit Profile app. The 13.5 cm (5.3 in) colour screen sits on the handle itself, so weight, BMI and body fat are read at eye level, with no bending down to the floor.
What owners say: It does what a good scale should, owners say, reasonably accurate and for some a match for the doctor’s office, and it’s easy to set up. They think it good value, find it handsome in the bathroom, and say the connection holds up well.
Heads up: Not for anyone with a pacemaker or another implanted medical device, or during pregnancy, as the maker warns.
A closer look: Stand on a hard, level floor, hold the handle and keep still for the 10 to 15 seconds a reading takes, since steady readings are what make the trend worth following. The maker calls the figures estimates for long-term tracking rather than medical readings.
- 8 electrodes, hands and feet
- Reading in 10–15 seconds
- Fitbit and Apple Watch too
Best for: Detailed body-composition tracking
- Readings in the app
- 50+

#5Vitafit Smart Scale with LED Display (black)
$10–$20
Thirteen readings, from weight and BMI to body fat, water and muscle, go to the Vitafit app and on to Apple Health, Google Fit or Samsung Health. It weighs in fine 0.05 kg (0.1 lb) steps, takes unlimited users, and Vitafit backs it with a three-year warranty.
What owners say: Pairing it with the app takes moments and it’s easy to live with, owners report, with tracking they find useful and a look they like. Accuracy, the Bluetooth connection and the app itself get mixed verdicts.
A closer look: Zero-Current mode weighs without sending a signal through the feet and shows just weight and BMI, which is how Vitafit suggests weighing babies and children. Every reading is kept in the app, so the weekly trend builds up without any notes to keep.
- 3-year warranty
