The best smart scales
Starting a fitness plan, or just want the numbers to log themselves? These scales send every weigh-in to your phone, so you can watch the trend instead of scribbling in a notebook.
A smart scale does two jobs. It weighs you, and it sends a small electrical signal through your bare feet to estimate body fat, muscle and water, then passes everything to an app that draws the graph for you.
Treat the body-fat and muscle figures as estimates: they're most useful as a trend, so weigh at the same time of day and compare week to week. Every pick here pairs with its maker's app, and most can share readings with Apple Health, Google Fit or Fitbit.
What matters
- The readings you'll actually use: weight, BMI and body-fat estimates.
- Bluetooth, or Wi-Fi for syncing without your phone nearby.
- Stones, kg or lb, and how many people can share it.
- Whether it links to Apple Health, Google Fit or Fitbit.

RENPHO Elis 1 Smart Scale
£35.99 RRP
A slim glass scale that sends 13 readings, from weight and BMI to muscle mass and a body-fat estimate, to the Renpho Health app, which passes them on to Apple Health, Google Fit, Samsung Health or Fitbit.
What owners say: Owners find it simple to use, like how much information it gives, say it links up well with the Fitbit app, and think it's well worth the price.
A closer look: It keeps readings when the phone isn't nearby and syncs them next time, so there's no need to open the app every morning. There's also a Renpho app for Apple Watch (not the original Series 1).

- Syncs with Apple Health, Google Fit and Fitbit

Easiest to read
Etekcity ESF-551 Smart Scale
£20–£30 Price range
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 0.05lb steps and tracks 13 measurements in its app.
What owners say: Owners find it easy to set up and use, say it's accurate and connects easily over Bluetooth, and reckon it feels like a pricier scale.
A closer look: Baby mode is handy for keeping an eye on a growing baby between clinic weigh-ins, or for a pet that won't sit still on the scale alone. Switch to Zero-Current mode when only your weight is wanted.
- 13 body measurements
- Extra-large LED display
- Baby and pet mode
- Zero-Current mode for weight only

Posture Smart Scale with Fitdays App (FG220)
£20–£30 Price range
A roomy 6mm glass platform, about 30 × 26cm, gives a steadier stand than a small scale, and its 13 readings go to the Fitdays app and on to Apple Health, Google Fit, Samsung Health or Fitbit.
What owners say: Owners find it well built and reliable, say it connects quickly and gives accurate readings, and find that watching the trend in the app helps keep them going.
Heads up: Pair it with the Fitdays app when you set it up: the full set of readings only appears once it's connected.
A closer look: Give each person their own profile in the app so readings don't get mixed up. Stand still with bare feet on the four electrodes, and the body readings come through with the weight.
- 13 body measurements
- 6mm glass, 30 × 26cm platform
- Syncs with Apple Health, Google Fit and Fitbit
- Up to 180kg
- White LED display

Best budget
eufy Smart Scale A1
£29.99 RRP
Small enough, at 26cm square, to slide under a cabinet in a tight bathroom, and it connects to your phone the moment you step on. It gives 12 measurements, and up to 16 people can have their own profile.
What owners say: Owners like how sleek and well made it is, find it easy to use, and say the app makes it simple to follow their weight and goals.
Heads up: It weighs in kg and lb only, not stones, so it suits anyone happy to switch to kilos.
A closer look: Keep it on a hard floor rather than a bath mat for steady readings, and step on barefoot so the electrodes can take the body measurements.
- 12 body measurements
- Compact 26 × 26cm
- Connects when you step on
- Up to 16 profiles
- Batteries included
Best for: Small bathrooms

What owners say: Owners love how smart and well designed it looks, and those who like the Withings app find it great for following their trends.
A closer look: There are modes for babies, pregnancy and athletes, plus one that hides the number at weigh-ins while still logging it, for anyone who'd rather not see it every morning. Carpet feet come in the box, for bathrooms that aren't tiled.
