Wireless Scale & Wi-Fi Body Scale: what’s different?

As we are about to release the Wireless Scale WS-30 in late September 2012 (in Europe), many of you ask us what the differences are between this new model and the original Wi-Fi Body Scale. Some already have the WBS01, our first generation of connected scales. Some are thinking of buying their first smart scale, and wonder which one they should buy. Which features are available on each of these two scales? What makes the Withings WS-30 a next generation connected scale? Here are the answers.


What differentiates the Wireless Scale from the Wi-Fi Body Scale?

1. A Bluetooth function

The Wireless Scale (WS-30) has an extra connectivity feature (compared to the WBS01). It has Bluetooth. This means you can do things you couldn’t do before:

  • The Wireless Scale offers a new cable-free PC-free experience! You don’t need any computer or Wi-Fi network to setup your scale. You can do it through a Bluetooth connection, standing next to your newly acquired scale, taping a few times on your smartphone or tablet.
  • You can weigh-in even without a Wi-Fi network. This means that after you step up on your Wireless Scale, it will beam up the tracking directly to your IOS device. This can come handy if your scale is too far away from your Wi-Fi router, if it’s down momentarily, or if you’re away from home in a Wi-Fi-free area: a cabin in the woods, an (under-equipped) hotel room, on the road in an Airstream…
  • This is what makes the WS-30 a next generation connected scale. Weight-tracking has never been so fun and easy.


2. An entry-level price tag

The WS-30 is our entry-level scale. It’s recommended retail price is €119.95, which is less than the price of the Wi-Fi Body Scale (our high-end model). The reason why this WS-30 is purse friendly is that, even though it measures your weight and BMI, it doesn’t measure your impedance, the body data necessary to give you your body composition (read the following paragraph for more details).



What feature does the Wi-Fi Body Scale have that the Wireless Scale doesn’t have?

Fat mass calculation

The Wi-Fi Body Scale measures weight, and calculates your BMI (Body Mass Index) and fat mass (how much fat – in percentage or in pounds/kilograms – there is in your body composition). The Wireless Scale does not calculate your fat mass.

  • Knowing your fat mass is interesting to have an idea of your risk of weight-related diseases. So is the Body Mass Index. But some say looking at your body fat mass (or percentage) is better because the BMI calculation applies a single equation over a diversity of physical conditions.
  • If you are in the process of loosing weight by exercising a lot, you will build muscle and shake off fat at the same time. The evolution curve of your fat mass will let you see how much fat is “turned” into muscle. Some might even get reassured to see that you can get healthier while maintaining the same weight.


What features do the Wi-Fi Body Scale and the Wireless Scale share?

1. No power on, no zeroing

Once setup, both scales are ready to be used everyday, right away. No need to switch the power on, no need to calibrate. Just step on it!

2. Position control

The Wireless Scale let’s you know if you’re in the right position to do the weighing. If not, it tells you what to do.

3. Automatic recognition

Both scales work for the whole family. When you step on one of these Withings scales, your trigram pops up shown on the screen. The scales recognize who you are among its recurrent users. Step on Withings scale and let it send your latest weigh-in to your online secured account.

4. Weight and BMI

Both scales measure weight and calculate your BMI with the same accuracy (100g graduation).

  • Your weight can be expressed in pounds (lbs), in kilograms (kl) or in stones (St Lb). You can switch units of measurement in the “Settings”.
  • Your BMI (Body Mass Index) is an equation mixing your height and your weight. Its result helps you assess if you have a healthy weight/height ratio. BMI categories: if your BMI is under 18.5 you are considered “Underweight”; from 18.5 to 24.9, you have a “Normal weight”; from 25 to 29.9, you are “Overweight”; and if your BMI is higher than 30, you are in the “Obese” category. Note: if you are a weight-lifter or a top level athlete the general BMI model isn’t going to be as accurate. On My.withings.com, once you have signed in, you can switch “body composition model” in the “Info” tab of the dashboard.
  • Easy-to-understand graphics which let you track your weight through time. Our app even creates a smoothed out curve based on your weight trackings, leveling peaks. We recommend you consider this curve to have a clear understanding of the trend your weight if following and to stay away from the emotional roller-coaster of day-to-day monitoring.

    actually, nothing seems to work with my partner, Training Peaks. been off for an hour now…. and even after logging it, i’m getting nothing. This is honestly the major reason I selected this scale, as I don’t use an iphone or Android device. Pretty disappointed.

    Seems strange to have a new model come out and leave out the bodyfat measurement feature. It would have been nice to have the option to have both the new features (eg, bluetooth) AND bodyfat measurement. Basically, bodyfat measurement is really a must-have; it’s a shame to have to get it in the “old”, previous-gen model for a higher price. It makes one wonder whether it was left out because it was not functioning accurately, or whether it was truly more expensive to manufacture.

    Hi Jimmy! Thanks for your comment! The Wireless Scale is our entry-level scale (we didn’t have one before). To get body fat measurement AND versatile connectivity (Bluetooth & Wi-Fi), you must wait a few more days: the Smart Body Analyzer will soon be available ;) You should submit your email on this page to get notified of its availability in your region: http://www.withings.com/en/bodyanalyzer/keepmeinformed

    Hi Stravos! The Smart Body Analyzer WS-50 has just been released and is available from our store: http://shop.withings.com/en_eu/smart-body-analyzer-black.html

  • http://blog.withings.com/ Withings

    Hi James! Sorry to hear that. Even though both boxes approximately have the same shape, the 2 models have distinct names. The new model of our flagship body scale is called “Smart Body Analyzer” or “WS-50″, and the original model “Wi-Fi Body Scale”. The icons on the package, detailing the features of the scale, are different – as well as the prices. And as you brought your scale in an Apple Store, we can’t do much. We advise you to look into their return policy. There might be a chance… Thank you for your understanding.

    Hi Friimpe! Water in the body is distributed between intra-cellular water and extra-cellular water. Monitoring the hydration rate is essential with a medical accompaniment, which we
    recommend in the event of any doubts.
    This is why we have chosen not to directly display the hydration rate in the Withings WiFi body scale for the general public. Thank you for your understanding.

    Hi Glen! Sorry to hear that you didn’t find this information. On the product page of the Smart Body Analyzer, in the Software requirements section, we wrote:
    • iPhone (3GS or later), iPad (all versions) or iPod touch (3rd generation or later), with iOS 5.0 or later and Internet access (mobile data or Wi-Fi)
    • Bluetooth-enabled Android smartphone or tablet with Android 2.3.3 or later, Internet access (mobile data or Wi-Fi)
    • Cannot be setup from a computer

    On the box itself, we wrote:
    • Software requirements
    iPad, iPhone, iPod touch running iOS 5 (or higher) required or Android device version 2.2.3 or later.

    As for your suggestion to allow for setups via a PC and to broaden the compatibility to other platforms than iOS and Android, I’ve forwarded it to the product manager.

    Thank you for your understanding.

    Hi Adam! Thank you for your interest! Actually both the original Wi-Fi Body Scale (WBS01), the WS-30 (Wireless Scale) and the WS-50 (Smart Body Analyzer) support up to 8 users :)

  • Sami Lauren

    My WBS01 suddenly stopped calculating Fat Mass. This happened at the end of the September. Why is that?? I’ve paid for that feature – I do not want the body analyzer scale.

    Hi Domnic! Just go into the side menu (tap on the “3 line icon” in the top left hand corner of the screen. Then, go into “Settings/Units”. Tap on “Fat mass in %” to switch off the option. You fat mass will be displayed in kg/lbs.
