Fitbit Aria Wi-Fi Smart Bathroom Scale, Black

Product information

The Fitbit Aria smart scale tracks your weight, body fat percentage and BMI and sync with you smartphone or computer, giving you a picture of your long term progress and help you stay motivated.

By tracking your body fat percentage and BMI, Aria can give you a more accurate representation of your weight in relation to your height to help you understand whether your body is in the healthy range.

Aria will identify you by your name or initials and display your weight and body fat percentage discreetly. It can link up with up to eight people at once, and keeps everyone's information private by default.

Aria will sync stats directly to the users private Fitbit account through Wi-Fi so you can see real time updates on your progress through the Fitbit app or on Fitbit's website. Your Fitbit account analyses the information it gathers and displays it in easy to understand charts and graphs and can then help you focus on long-term trends. You can even earn badges as you achieve your goals to help give you that extra bit of motivation.

Q & As

Rated 3.2 out of 5 by 19 reviewers.
Rated 4 out of 5 by Great if you're a Fitbit-er I'm not going to lie, setting this product up was an absolute pain. I got to the point where I thought I would have to return it for not working. After much research on the internet I finally got the scales to sync with my wifi using the 'mobile' method. Once this was set up though it worked brilliantly. I use a Fitbit Charge HR and my wife uses a Flex and we share the scales. It automatically recognises each of us and syncs the data into our own apps separately. It's very slick If you've got money to burn and you'd rather have this data automatically sync into your app then I'd highly recommend it or else just use a pen and paper! 17 March 2015
Rated 5 out of 5 by No set-up problems here It took me less than five minutes to get this set up, and it's syncing with my Fitbit account exactly as it should. Can happily recommend. 06 March 2015
Rated 1 out of 5 by Good idea but rubbish software I real wanted this to work so I tried with 3 PC's and could not get it to interface. Returned it . 18 February 2015
Rated 5 out of 5 by Fitbit Aria It took me about 3 mins to set this up. The procedure is pretty standard for configuring internet connected 'things' in the home. There are quite a lot of negative reviews on here, but i really couldn't fault this. Works exactly as it should, looks great, build quality is good. For me, It just works! 16 February 2015
Rated 2 out of 5 by Very frustrating setup procedure It took all the patience I possess to set this thing up. From the slick appearance of the scale and the smart-looking automatic setup software you could be forgiven for thinking it's all very simple and user-friendly. Sorry, but it's just not. I contacted Fitbit support after it repeatedly failed to recognise my wifi network, and was given a checklist to work through. In the event nothing on the checklist turned out to be the problem, and it was only by pure luck that I got it to work (in my case denying access to the keychain on OSX and putting my wifi password in manually). I consider myself a fairly tech-friendly person and I was on the verge of taking this back, so my advice is if you're looking for something that's easy to set up and use, get another brand. It seems to be fine now that it's set up, but boy was it a headache to get there. I just don't expect this level of fuss and bother from a mainstream consumer product, so regrettably I don't recommend it. 12 February 2015
Rated 1 out of 5 by Manufacturing fault I bought this from John Lewis Bristol and when I set it up it displays an error message, and will not function. After going through the appropriate trouble shooting, I contacted fitbit customer services (no UK contact number) and it appears that this is a known issue for multiple users and the scale is faulty. Just check on their own forum and you will find vast numbers of people with the same issues. There is obviously an un-addressed manufacturing fault. Other users report this fault both from new, and when changing batteries for the first time. Buy this product at your own risk. 28 January 2015
Rated 1 out of 5 by Find an alternative It took hours to set this product up with the app on my phone. I was then unable to set it up to another device for another user. It is also inaccurate. It recorded my bodyfat as 40%. I compared this to two other sets of scales and body fat calipers, all of which were consistent in readings of 18-20%. I have returned this product and exchanged it for a similar Withings scale which is so much better. 03 January 2015
Rated 5 out of 5 by Fitbit Scales - Ours are excellent....great them... We have a Fitbit One each so thought to be consistent and sync over wi-fi would be fun..and it is... Ours set up first time and without a problem, easy to change weight from lbs to kgs etc...but you all then get same read out...not really a problem once you get used to kgs..we use MyFitnessPal to, so stay with kgs. The scales remember each used ID...up to 8 per weight association i think..had no problems with this. The read out on the scales says what is in progress..weighing..logging..uploading.. As with all scales where you stand may alter the weight reading a little...always best to take the average of say 3 readings if you are really bothered about this...delete the ones not needed off the Fitbit weigh what you are really only looking for changes..say once or twice a week. The extra data of BMI and body fat % is a calculates these and uploads them as well...go on the internet for male and female body fat will be very surprised at what you see...! The design is quite cool too.. In all, ours work well and give added fun and value to trying to stay a bit more fit and healthy. We would purchase again and love the product...enjoy. 14 November 2014
