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.
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
- Your heart rate
- Your body-fat ratio
- The temperature and CO2-levels in your room
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. Here’s what I like about it:
2. 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.
3. 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…
This is the first in a series of product reviews here on the Addapp blog. To stay up-to-date and make sure you don’t miss out on the next posts, make sure you follow us on Twitter and like our Facebook page!
And that brings me to the things I don’t like
1. 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.
2. 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.
3. 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.
So, would I recommend forking out the extra $50?
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.
Have you used the Withings Smart Body Analyzer? We’d love to hear your thoughts in the comments.
