In the coming weeks we’ll be reviewing self-measuring gadgets that we use. We will tell you what we like about them and what not.
Let’s kick-off with the Withings Smart Body Analyzer or WS-50.
Like it’s smaller brother, the WS-30, the Smart Body Analyzer is a Wi-Fi scale but with more functions. In addition to your weight, it also measures
The WS-50 sells at $50 more than the WS-30. Is it worth the extra money?
I’ve been using it for seven months.
I love the automatic Wi-Fi-sync. It works like a charm. As soon as I’m off the scale I can look at my data on the well-designed Withings mobile app (image to the right).
I like the fact that it measures CO2 levels and the room temperature: it gives me two more variables that may influence my sleep. As a self-measuring freak I am always looking for connections and the more data I get, the higher the chance that Addapp shows me a surprising revelation.
The resting heart rate is an important health indicator: I want to measure it every day. The best moment to capture it is in the morning, right after waking up. I can think of no more comfortable way to do that: I just have to hop on the scale, wait a few seconds and voilà: there’s my heart rate…

It’s a shame but the heart rate just isn’t accurate. I compared the results with Withings blood pressure device: the WS-50 is up to 20 beats wrong, making the function effectively useless.
The WS-50 isn’t portable. True, the WS-30 and all other scales have the same problem but I wish I could roll it up and stuff it in my bag. I want to measure every day and I have to enter the data manually when I am on the road. That’s inconvenient even though I don’t travel that often.
The body fat measurement is another promising function that doesn’t work well in practice. The major problem here is the software. You have to tick a personal profile on the app. But look at the choices you get:
These choices sound more like software versions than body types. As weird as they are, I could live with them if I knew how to pick the right one. But there’s no such explanation. And as I get very different results in each setting, I can’t even start to make sense of it all.
I’d be very happy with the WS-50 if the heart rate and fat mass measurements worked.
Not that I am unhappy: the scale measures my weight accurately and syncs ever so well. But, I assume the smaller brother does that just as well. The only reason to upgrade would be to measure temperature and CO2 in the room – is that worth 50 bucks? I don’t think so.
