Head to Head: Withings WiFi Body Scale vs Fitbit Aria Scale [Review]

Withings WiFi Body Scale – $190.69 – £119.00


The Withings WiFi Body Scale device is slightly more expensive than the Fitbit, but also offers the same kind of electronic wizardry to deliver your weight, fat mass and overall BMI (body mass index) ratios to an online dashboard via your home WiFi. However, instead of integrating with a Withings fitness program, the scale is compatible with generic online fitness programs such as Daily Burn and RunKeeper. It also syncs with Google Health.


Like the Aria, the WiFi Body Scale runs on four AA batteries, which should last a few months before needing replacement, and the device is also capable of tracking the stats of up to eight people. We have to say that the overall ergonomics and design of the product also comes across as more appealing, it’s thinner, more shiny and the dial is definitely more legible in bright light. What we didn’t like so much is the fact that you inevitably leave a lot of fingerprints and smears on the glossy black surface from day to day handling, but we guess this is the price you pay for any shiny black object.


Set up of the Withings scale is also unfortunately more complex than the Fitbit Aria. Instead of simply logging on to an online wizard, you need to plug the scale into your computer via a supplied USB cable and run through a fairly cumbersome install process. We also had a few glitches trying to get the scale to install properly, which we are surprised to find on a product of this quality.

Once installed, the scale is great to use. Unlike the Aria, this scale comes with carpet feet for softer surfaces, but you so still need the bare feet for the body mass measurements. However the Withings is much faster in operation, and the results appear to be much more accurate. This could be because it gives a more granular result (including pounds and divisions) or because there’s a logical consistency in the results, we had no massive jumps or dives in weight as with the Aria, just a steady movement in either direction from day to day, week to week.


We felt more confident that the scale was actually working accurately, which we didn’t get from the Aria so much. The online dashboard for the scale is however not as intuitive or all embracing as the Fitbit one. The scale charts nicely, no question, but we found the interface to be a little more clunky, and initially the dashboard had problems identifying who we were until we told it. It’s not that the interface is awful, it’s just not as flexible as the Fitbit one (for instance there’s only a couple of charting options) and not as easy to do a time comparison.



The Withings WiFi Body Scale is a very good product, but there are some surprising issues in a few areas. The installation is a bit of a rigmarole, the synching has glitches and there’s definitely work that could be done to improve the user interface for the user dashboard. But apart from these issues, we have to give this device the edge in the head to head. It’s elegant, much faster, very accurate and just feels like it’s more of a solid product (even though the Aria has a heavier heft). The issues with the dashboard could easily be fixed with a bit of design intelligence, and even so the Withings is still the product to beat in this arena.

Pros: Lovely looking product, beautifully clear dial and fast in operation. Offers solid functionality in the areas that matter the most.
Cons: A little kludgy to install and set up, and the user dashboard could do with a more lightweight and modern makeover (or at least some themes). Also needs more upfront user help with integration with other online services.

Verdict: 8/10

  • I actually just purchased a Withings scale last week, and just wanted to add – fitbit's website plays nicely with the Withings scale. So, you can combine the nicer Withings hardware with the more polished fitbit website. Best of both worlds!

  • I’ve been using my Withings for over two year now and use it every day. Seeing one’s weight history really help in pursuing your efforts. Can’t recommend enough such a purchase.
    You can also monitor your weight using the Runkeeper application.

  • Hi Clippy and Nigel! Here's something I'm sure you'll like!

  • BTW Clippy, have you seen the free Health Companion app? It's our latest 4-in-1 health monitoring iOS/Android app :)

  • If you ever try to take Withings scale apart you will see it is put together with only double-sided tape which corrodes over time in humid environments! For paying, $159 I would expect a better build quality. Fitbit is much better build quality.

    Since the Body Fat weight scales pass a current through the body , they are a Class II Medical Device. Fitbit Aria “doesn’t even have FDA approval/clearance” for marketing it. Selling unapproved product is illegal as per FDA. Withings sold body fat scales for 2 years illegally before getting the FDA clearance.

    Lastly, both scales get completely confused if 2 people in the home are within 5-7 lbs of each other. So make sure of who all are going to use it before investing and what their weights are before buying.

    If you took multiple Body fat readings on any scale, expect to see wildly different readings- amazing how you would seem to lose or gain body fat so quickly:)

    • Thanks for the feedback. I was also amazed by the huge variations in body fat from day to day. Mysterious indeed.
