What's in the range
- Smart scales: bathroom scales that log every weigh-in to a phone app, so you see how things change over weeks and months. Besides weight, they estimate body composition, such as fat and muscle. Higher-end models add further readings.
- Activity trackers: slim bands that count steps, record exercise and monitor sleep, with a small display for the time and notifications.
- Smartwatches: the same tracking on a bigger screen, plus alerts for messages and calls. Calling watches include a speaker and microphone so you can answer from your wrist.
- Circulation boosters: you rest your feet on the unit while sitting, and electrical muscle stimulation makes the muscles in your feet and calves tense and relax.
Which product suits you?
| Product | Suits | Worth checking |
|---|
| Smart scale | Following weight and body composition trends over time. | Which readings it takes, and whether it connects by Wi-Fi, Bluetooth or both. |
| Activity tracker | Counting steps and logging sleep with something light enough to forget you're wearing. | Battery life and whether the app supports your phone. |
| Smartwatch | A clearer screen, phone alerts and, on some, calls from your wrist. | Case size, screen type and water resistance. |
| Circulation booster | Stimulating the feet and lower legs while you sit. | The intensity levels, a remote, and whether body pads are included. |
Making the choice
How much detail from a scale?
Any smart scale records weight and keeps your history in the app. The question is whether you also want the wider set of body composition figures. Treat those as estimates, most useful for spotting a trend rather than as precise numbers. Most scales recognise several people, which suits a shared bathroom.
Tracker or smartwatch?
A tracker is light, low-key and comfortable in bed. A smartwatch is easier to read and does more, but it's bigger. To take calls without your phone in hand, choose a calling watch. Colour AMOLED displays are brighter and crisper than standard screens, which helps in sunlight.
Will it work with your phone?
All of these depend on an app, so confirm it supports your phone first. Scales link by Wi-Fi, Bluetooth or both; with Wi-Fi, readings upload even when your phone isn't nearby.
Battery life
Expect to charge a watch or tracker every few days or so, depending on its display and which functions you run. Scales are far less demanding, lasting months per charge or set of batteries.
Circulation boosters
Compare the number of intensity levels, check for a remote so you needn't bend down, and see whether pads are included for use on other parts of the body.
Before you order
- These aren't diagnostic medical devices. Treat the numbers as a guide to general fitness, and see your GP about anything that worries you.
- Check who shouldn't use it. Muscle stimulators, and scales that send a current through the body, can be unsuitable during pregnancy or for anyone with a pacemaker or similar implant. The manufacturer's guidance explains this; ask your GP if in doubt.
- Weigh on a hard floor. Scales give the most consistent readings on a firm, level surface rather than carpet.
- Check the fit. Slim wrists especially: check the watch face dimensions and strap options listed.
- Check water resistance. Not every watch can go swimming or in the shower.

Health & Fitness: your questions answered
What does a smart scale measure?
Weight first, then estimated figures for things like body fat and muscle. Results are saved to an app, building a picture over time. Advanced models add extra measurements.
How accurate are the body composition figures?
They're estimates, worked out from a tiny electrical current sent through the body. They're best for tracking change over time, weighing at the same time each day, rather than as exact values.
Activity tracker or smartwatch?
A tracker is a slim band for steps, workouts and sleep. Smartwatches add a larger display and closer links to your phone, from notifications to answering calls on the calling models.
Do I need a smartphone?
For scales, trackers and watches, yes. Setup happens in an app, which also keeps your history. Confirm your handset is supported first.
What does a circulation booster do?
Mild electrical pulses from the footplate work the calf and foot muscles, tensing and relaxing them as you sit. Read the manufacturer's guidance on who it's suitable for before you buy.
Can a household share one smart scale?
Usually, yes. Most smart scales identify different people and file their results under separate profiles; the product page says how many users it supports.
