Renpho vs Withings Smart Scale: Which One Should You Buy?
Written by Dr Muhammad Usman, MBBS
Two names come up often when UK shoppers look for a smart scale: Renpho and Withings. Renpho usually costs around £20 to £30. Withings Body Smart costs £89.95 in the UK, with the premium Body Comp at £139.95 (on sale).
The practical question is whether Withings is worth paying more for.
The honest answer is: it depends entirely on what you want the scale to do. This guide breaks down every meaningful difference between them so you can stop going back and forth and just buy the right one.
If you want to convert any reading from either scale, our kg to stone converter and stone to kg converter are available. And if you are unsure what your weight means for your health, our BMI calculator puts the numbers into NHS context.

Accuracy: Are They Actually Different?
For raw weight measurement, the difference between Renpho and Withings is likely to be small. Both use load-cell technology and convert the measurement to the display unit you choose.
Research on consumer smart scales has found median weight errors of under one kilogram compared with clinical readings. Treat that as general context, not a guarantee for every model.
Where they genuinely differ is body composition. Both use bioelectrical impedance analysis (BIA) to estimate fat, muscle and bone. The Withings app uses a more developed algorithm and presents the data alongside reference ranges and trend context, which makes the readings more useful in practice. Renpho’s BIA readings are accurate enough to track trends over time, but they can fluctuate more noticeably day to day.
For pure weight tracking, both are reliable. For body composition, Withings gives you more confidence in the numbers.
App Quality: The Biggest Difference
This is where Withings has the clearest advantage. The Health Mate app presents weight trends with clear graphs and adds context around BMI and changes over time.
It can also combine scale data with sleep, activity and heart-rate data from other Withings devices.
The Renpho Health app is functional and easy to use, and it connects to more third-party platforms than Withings does, including Samsung Health and Fitbit. But the data presentation is simpler and there is less context around what the numbers mean for your health.
If the app experience matters to you and you want your weight data presented in a way that helps you make decisions, Withings is meaningfully better.
Connectivity: Bluetooth vs Wi-Fi
Renpho connects via Bluetooth only. This means your phone needs to be nearby when you step on the scale for the reading to sync. It is not a dealbreaker for most people, but if you leave your phone in another room while you weigh in, the data will not transfer until you open the app.
Withings Body Smart adds Wi-Fi. You step on the scale, the reading syncs to your account automatically regardless of where your phone is. For households with multiple users, this is particularly useful because each person’s weight goes to their own profile without anyone needing to manage it.
Setup Compared: What to Expect Out of the Box
Renpho setup is quick and app-first. Download the Renpho Health app, enable Bluetooth, create an account, then step on the scale to wake it and pair. The whole process takes a few minutes and is forgiving if you make a mistake.
Withings setup takes slightly longer but pays off afterwards. Install Health Mate, create an account, pair over Bluetooth, then configure Wi-Fi inside the app for automatic syncing. The extra minute of setup gives you automatic cloud syncing from then on, with no phone required nearby.
The practical difference: with Renpho, your phone must be nearby with Bluetooth on for every weigh-in to sync. With Withings, Wi-Fi handles syncing automatically in the background, so weigh-ins upload even when your phone is in another room.
Long-Term Value: Beyond the Sticker Price
The price gap (£89.95 vs under £30) looks large, but the total cost picture is more nuanced.
Battery and maintenance. Withings advertises around 15 months from 4 AAA batteries. Renpho battery life varies with use but is generally measured in months. Neither scale has a subscription requirement for core features, though Withings promotes its optional Withings+ service.
Build and longevity. Withings uses a heavier tempered-glass chassis with a premium feel that tends to hold up well over years. Renpho is lighter and more portable but feels less substantial. Both should last for years of normal bathroom use.
Resale value. Withings scales retain more secondhand value thanks to brand recognition. This rarely decides a purchase, but it reflects the build quality gap.
When Renpho is the smarter long-term buy: if you are unsure whether you will stick with smart-scale tracking, spending under £30 to find out is sensible. You can always upgrade later.
When Withings pays for itself: if you weigh daily for years, the Wi-Fi auto-sync, better app and longer battery life compound into a noticeably smoother experience.
Stone Display: Only Withings Handles It
For UK users, being able to weigh in stone matters, and this is a clear differentiator. Withings supports stone display (kg, lb, st lb). Renpho does NOT support stone display: it shows kilograms or pounds only.
For Withings, the unit is changed through the Health Mate app under Profile and Preferences. The underlying data is always stored in decimal kilograms, so switching display units never changes your historical data.
If you buy the Renpho and think in stone, you will need to convert readings manually. Our kg to stone converter gives you the answer immediately.
If your scale is currently showing kilograms and you need to convert the reading, our kg to stone converter gives you the answer immediately. For a full explanation of why smart scales default to kg in the first place, see our guide on why smart scales use kilograms.
Who Each Scale Is Best For
Renpho is ideal for:
- Anyone buying their first smart scale and wanting to try one without a big financial commitment
- People whose priority is weight tracking rather than detailed body composition analysis
- Households where everyone uses different health apps and needs broad compatibility
- Anyone who is budget-conscious
Withings is ideal for:
- People who want the best app experience available on a smart scale
- Anyone who tracks health data seriously and wants meaningful context alongside the numbers
- Households where auto-sync matters because multiple people use the same scale
- People who may expand into other Withings health devices (blood pressure monitors, sleep trackers)
- Anyone who is pregnant or wants pregnancy mode tracking
How We Compared These Two Scales

All specifications were verified from official manufacturer websites (renpho.com and withings.com) in October 2026. Key verified facts: Withings Body Smart costs £89.95 with Wi-Fi + Bluetooth and stone display; Renpho Elis 1 offers 13 metrics over Bluetooth only with kg/lb display and no stone support. We did not physically test either scale.
Interpreting the Comparison
Dr Muhammad Usman, MBBS
Both scales can be useful for recording weight trends. The more expensive scale is not automatically more accurate for weight; the main differences here are app features, connectivity and how body-composition estimates are presented.
Weigh yourself at a consistent time, ideally in the morning after using the bathroom. Body weight fluctuates during the day because of food, water and clothing, so a consistent routine makes the trend line more useful. A single reading in isolation tells you very little.
If you are unsure whether your current weight is healthy for your height, our BMI calculator gives you an NHS-aligned result in both stone and kilograms.
