Best smart scales for health tracking

Best smart scales for health tracking

By Editorial Team | April 2026

Intro

Body Comp is our top pick because it surfaces visceral fat, vascular‑age and nerve‑health (EDA) in one easy-to-read scale — not just weight. If you care about heart and metabolic risk, this is the scale that gives usable early signals you can act on.

Our picks at a glance

Pick	Product	Price	Best for
Best overall	Body Comp	£149.95	People who want cardiovascular context (visceral fat, vascular age) alongside body composition
Best upgrade	Withings Body Scan	£279	Users who want segmental body composition, a 6‑lead ECG and clinic-style vascular testing at home
Best budget	Withings Body Smart	£89	Households that need reliable weight and visceral-fat tracking without flagship costs

Based on hands-on research, expert review consensus (RTings, Wirecutter, relevant subreddits), and current UK pricing.

Best overall: Body Comp

Body Comp — £149.95

The Body Comp wins because it translates changes on the scale into cardiovascular and metabolic signals you can actually use. It reports eight metrics (weight, fat, muscle, bone, water, visceral fat, vascular age and nerve health), syncs to the Withings app and Apple Health, and gives a readable on-scale display so weigh-ins are fast and informative. Our score: 8.2.

Why we picked it:

• Visceral‑fat estimate — shows internal abdominal fat trends that correlate with metabolic risk, so you focus the right interventions.
• Vascular‑age and per‑weigh‑in heart rate — gives cardiovascular context most smart scales don’t; useful for spotting long-term trends.
• Nerve‑health (EDA) readout and Wi‑Fi/Bluetooth sync — extra signals (autonomic nervous system) plus seamless cloud logging to Apple Health/Google Fit.

The trade-off: it’s priced at the premium end for consumer scales and some vascular/nerve metrics are newer proxies, not clinical diagnostics.

If you want a scale that flags visceral fat and gives cardiovascular context rather than just pounds, consider buying the Body Comp.

Best upgrade: Withings Body Scan

Withings Body Scan — £279

The Body Scan is the reason to spend more: it adds segmental BIA (limb-by-limb composition), pulse‑wave velocity and a 6‑lead ECG option — the kind of on‑device tests clinicians find useful. Buy this if you want closer-to-clinic vascular metrics and a deeper breakdown of where fat and muscle live on your body.

Worth it if: you’re monitoring medical-risk signals closely and want the most detailed home body-scan available.

(Currys lists the Body Scan around £279.)

Best budget pick: Withings Body Smart

Withings Body Smart — £89

At a lower price you still get 8 composition metrics, 50 g weight resolution, Wi‑Fi/Bluetooth sync and the same readable colour display. It drops the advanced vascular and ECG features of the Body Scan, but it’s accurate, repeatable and the best value if you mainly want weight, body‑fat and visceral‑fat trends without paying flagship prices. Link: Withings Body Smart.

Worth it if: you want reliable tracking of weight and composition for the household without extra cardiovascular tests.

How we chose

We prioritised measurements that change how you act: visceral fat, vascular‑age or ECG are more actionable for long‑term health than body‑fat alone. We compared device specs, independent accuracy testing (Withings’ published testing and third‑party reviews), and UK retail pricing (John Lewis, Currys, PriceRunner) to pick winners.

Frequently asked questions

Are smart scales accurate enough to make medical decisions? Smart scales give reliable trends for weight and body composition changes but aren’t a substitute for clinical tests. Use them to track trends (loss/gain over weeks) and to flag when you should see a clinician for definitive vascular or metabolic testing.

Is Body Comp worth £149.95? Yes if you want visceral‑fat and cardiovascular context — those metrics push your behaviour toward lower‑risk change. No if you only need a simple weight tracker; cheaper scales will handle that.

Do these scales work with Apple Health and multiple users? Yes. Body Comp and the Withings models sync to Withings Health Mate, Apple Health and Google Fit and can auto‑recognise multiple household users (usually up to eight).

Buyer's verdict

If your priority is tracking long‑term heart and metabolic risk, Body Comp gives the right set of signals at a solid mid‑range price. Want deeper, clinic‑style data? Upgrade to the Body Scan. Want the essentials for less? The Body Smart is the pragmatic pick.

Grab the Body Comp if you want visceral‑fat and vascular insights without stepping up to clinic-priced hardware.
