    Measures weight, body fat and water percentages, muscle and bone mass

    How?

    • SevenSmurfs on 18/11/2016 - 20:46

      Scales that measure body fat do this by sending a low electrical current through one foot and reading the current with a sensor under the other foot. The current passes through fat more slowly and the scale calculates the amount of resistance to come up with a body fat percentage. The accuracy of these body fat measurements should be taken with a grain of salt as they can be inconsistent and inaccurate at times.

      • Unseatingcargo1 on 18/11/2016 - 21:01

        They are inaccurate, BUT they seem to be relatively consistent. Though the initial measurement may be inaccurate, the actual deviation from that measurement should be relatively accurate.

          Your imaginary concept of how it works and why it should be consistent is cool.

          @Diji1: A lot of people from the fitness community stand by what I say. The initial reading is wrong, but you can use that as a control for future weigh ins.

        • Unseatingcargo1 on 18/11/2016 - 21:51

          @Diji1: Jesus mate. What you're looking at is consistency in the readings and the trend that follows. DEXA scans aren't even very accurate, so nobody at all should be relying on this form of body fat measurement.

        • tazmaniak on 18/11/2016 - 21:53

          @Diji1:
          I use a similar thing at home. It consistently tracks fat loss. Yes, my bodyfat percentage is about 1% higher than what it states, but it accurately tracks trends down and up. Bear in mind that if you eat relatively low carb, your water retention will drop and the fat percentage will read higher than normal. You can tell because it'll read muscle mass as being higher/bf lower after carb-loading.

        • ProspectiveDarkness on 18/11/2016 - 22:10

          @Diji1: You might want to actually check on the scientific terminology before running your mouth like that.

          In the case of tracking changes, precision is better than accuracy. Accuracy refers to the closeness to the exact desired target value - in this case, the actual weight. So with higher accuracy, you might be closer to the real world figure, but you can still be inconsistent with the measurements and have a higher deviation between data points, they'll just be closer to the target on average. Precision refers to consistency of the results; so you'll consistently get similar values over a smaller range with high precision.

          So once you establish a baseline, whether right or wrong, you can track changes in weight with high precision, but low accuracy. The numbers can be wrong, they just have to be consistently wrong.

          So yes, when people talk about the scales working fine because they're consistent, they're right. You don't just assume it's consistent (AKA high precision), you check it by repeating the same measurements and comparing them. Accuracy is nice, but it's not what's important here.

          Source: have actually been educated on how to perform science experiments.

        • 8azinga on 18/11/2016 - 23:16

          This review shows that it isnt even consistent, being just under 1kg different after after doing 2 measurements within a minute of each other

        • EightImmortals on 19/11/2016 - 03:25

          @gazza88: Yeah I bought a similar scale a couple of years back and the weight measurements were erratic to say the least.

          @Diji1: Rekt.

        • pos on 19/11/2016 - 11:18

          I really wish manufacturers just released measurement statistics of these things. It would definitely put this to rest.
          Nobody has really posted any evidence that these scales really have good precision. And that's not to mention that they don't suffer from other problems, like scale-factor errors. If they do, then they basically have no use at all, unless you manage to keep the exact same body fat percentage and weight…

        • hell0 on 19/11/2016 - 12:25

          @Diji1:
          That is pretty rude of you Diji1. I hope you hold yourself to such high standards as you impose on others. Of course you don't, but i am sure you tell yourself that your intentions are what matters. lol

    How does this compare to Fitbit Aria?

    • cryptos on 18/11/2016 - 21:22

      I have Fitbit aria, imo it is much better than these:

      Wifi uploads direct to Fitbit online, no Bluetooth needed
      Fitbit site offers good tracking platform as stated these types of fat calculators are best when you can plot the information over time, also the Fitbit apps read the online information and provide plots graphs etc

      • Diji1 on 18/11/2016 - 21:37

        fat calculators are best when you can plot the information over time

        Why is that best when they're wildly inaccurate? Only a fool would even use it for that.

        • cryptos on 18/11/2016 - 22:31

          What he said above, deviation over time will give you an indication of weight gain or loss, works for me, what is your solution?

    • boomramada on 18/11/2016 - 22:43

      $100 more?

      • [Deactivated] on 19/11/2016 - 00:31

        Before this deal they were both around $150 so they were kind of on par price-wise

    • bagachin on 18/11/2016 - 23:53

      I hit the buy button and yet to use this, but I have a broken Fitbit Aria after about 2 years of on and off usage (hence the purchase). I would say that when it's working, its very convenient and it just synced over the WiFi. I can only assume Fitbit Aria will be much more convenient than the constant resync of the Bluetooth like this one is. Like many said, accurate or not, not my major concern, I am aiming to track the movement and trend of my weight. So as long as it sync easily and measure consistently, I am happy as Larry.

      Lastly, Fitbit costs 3 times more, so my expectation for this scale will likely be 3 times less than what I have with Fitbit, considering how much it is and what it offers, I think it will be a good enough product.

  • [Deactivated] on 18/11/2016 - 21:04

    Wait, so you can't use this with my fitness pal app??

    • O O on 18/11/2016 - 21:20

      It showed up in myfitnesspal apps list. I think they should work together, as myfitnesspal just pull the data from libra app/site.

  • BuyNow Think Later on 18/11/2016 - 21:40

    What type of batteries it uses?

      I think so, it's in the Google App Store.

      • BuyNow Think Later on 18/11/2016 - 21:47

        Thanks. It states "The Runtastic Libra app requires the Runtastic Libra Scale." without the Fitness. This is a "Runtastic Libra Fitness Scale".

          Yeah seems that it works on Android but it didn't on launch. A 2013 review said iOS app only but this 2015 review mentions android app and also on their website.

        Yeah I get what youre saying, more people gave it 5 stars but more people gave it 1 star than gave it 4 stars

        • Domingo on 19/11/2016 - 08:15

          And the same percentage for the number of people who gave it 3 star vs 2 star.

          I can point out numbers too.

          @Domingo:

          You could also look at it like 3.2 ppl out of 10 gave it 5 stars and 2.5 ppl out of 10 gave it 1 star.

          The question for me then becomes is the half persons opinion worth more that the one fifths persons opinion?

  • tomlikesbeetroot on 19/11/2016 - 01:45

    I've owned one of these for about 2 years and very happy with it.

    Weight results can vary if you move it around a lot, I use it in the exact same spot on a hard surface and it's very consistent.

    It was within 2% of a dexa scan for body fat readings.

    The app is also good, never has any issues with the Bluetooth connection. Does a good job of storing history and showing trends, integrates seamlessly with myfitnesspal.

    Can anyone else speak for the accuracy of this?
    Interested in a scale that can accurately measure body fat but I read online that this could vary up to 10% bf difference

    • ozlab on 19/11/2016 - 06:52

      plenty of reviews at amazon.com

  • rodtp on 19/11/2016 - 06:57

    I grabbed one this morning. I was after one of those "smart" scales but I couldn't justify paying $150+. The black model is now gone, the white one still showing in stock. Thanks OP!

  • fozzie on 19/11/2016 - 09:00

    Blimey, I ordered a xiaomi only a week ago!paid the same as this but is coming from China. Would have prefered this at this price

    A friend and I bought one of these each a few years ago. they were both inconsistent with each other and did not match skin fold tests I had to measure fat content. I personally wouldn't recommend the product

    • stonkered on 19/11/2016 - 13:22

      I reckon most know what they're getting in to for $50.

      • adamjb007 on 19/11/2016 - 13:51

        I'd buy this for $20 and keep my $30 https://www.bigw.com.au/product/house-home-glass-digital-bat…. The benefit of the runtastic scales really lies in the app why you get graphs and data records on your phone so it is useful in that sense

        • [Deactivated] on 22/11/2016 - 19:01

          Id rather pay the $30 and get all the extra info and convenience of my weight automatically saved. With that you get nothing and you'll have to write the info down.
