GreaterGoods WiFi Smart Scale

Amazing product, so much better than the more expensive Fitbit variant. My FitBit Aria scale got soaked when our sink leaked onto it and killed it, so I was looking for something to replace it with. Since it's shared between my girlfriend and I, it needed to support multiple independent users. Additionally it needed to sync all the data to FitBit, without requiring an app on the phone to sync the data between a third-party service and FitBit. It had to take body fat percentage as well as weight, and had to sync via WiFi. This product meets all those requirements, though the product description before purchase wasn't clear about the syncing with FitBit occurring without an app present. When it arrived, it simply contained the scale and a little piece of paper saying to go to a website for setup instructions and product registration. Going to the website prompts you to register your device by using Amazon authentication (like "log in with Facebook", but with an Amazon account). That automatically linked against the purchase they had recorded from my Amazon user, and registered the product for me. It also seemed to make the rest of setup even easier. Before you use the scale the first time, you're supposed to set it up. It seems it will still take all the same data if you don't go through setup with it first, but doesn't know who it's for or what to do with it so it will delete it after displaying it. First time setup _requires_ an app on either Android or iPhone for each user, and will walk you through your account setup with their own Weight Gurus service, user preferences for the scale, and connecting the scale to your WiFi (if no one else has connected it to WiFi yet). It was all very straightforward and worked pretty well. At the end, they ask you to step on the scale to get a first reading. My first time on the scale I had it on a slightly cushy surface, which made it think I weighed only 80 lbs (I weight 175). After the first time weigh in though, I got an accurate reading when placed on a hard surface, and was able to delete the original incorrect reading very easily from the app on my phone. Despite the app on your tablet or phone being required for setup for each new user (a different device is recommended for each user, but apparently not required), you don't actually need to keep it on your device after setup. My girlfriend didn't have space on her phone, so she deleted it and hasn't had any problems with it taking readings, sending the data to FitBit, or in controlling settings from the web login of her Weight Gurus account. If you keep the app on your phone, you can get notified of results every time you weigh in, track history of off kinds of data, set goals, etc. In addition to reading your weight and taking your body fat percentage (you select between Average and Athletic for the algorithm it uses to determine body fat percentage), it also determines your BMI based on the height you enter in your user profile, water content, bone mass, and muscle mass. It displays them as a series of numbers underneath your weight that iterate through the sequence after it completes sensing. It does a good job of detecting between multiple users (though there's a warning about auto-detection between users who are really close in weight), and better than the Aria it will actually indicate with an icon (U1, U2, U3, etc) which of the users it thinks you are. Also better than Aria, if you do expect you'll have problems with auto-detecting between users, they have a couple capacitive touch buttons in the middle of the scale where you wouldn't normally step, that allows you to manually select your user in a very intuitive fashion. While I'm not personally concerned about it, there is an interesting mode provided on a per-user basis for how the data measurements are displayed on the scale. If enabled, the measurements can be a +/- number since your last weigh-in rather than an absolute value that reveals how much you actually weigh. If you were concerned with keeping that information private, you could set that mode for your user to be able to get immediate feedback relative to your last weigh in without others knowing your full weight. You're still able to see full details on the web site or app though, so you're not missing out on the full feature set. I assume it's an intentional feature, but my only annoyance is that the angle of view on the on-scale display is pretty narrow. I have to bend down to slide the scale out from under my sink, and slide it back under (it sticks to the floor really well and doesn't want to slide without lifting), so I'm frequently trying to slide it back under the sink after it's finished with readings and is uploading to the cloud. That's when it cycles through all the extended stats like bone mass and water content, so I normally try to watch it while putting the scale away. The viewing angle of the LCD is so narrow though, that unless I have my face almost directly above the screen, I can't see what's on the display at all. Pros: Easy to setup Lots of data taken/tracked Simple interface Great auto-detection between users Lots of intelligent features. Links to FitBit without requiring an app to do the sync Does't require the app to use it after setup Links to a detailed Weight Gurus tracking system Provides basic measurement information even without connection to a Weight Gurus account Cons: Requires the app to setup Narrow angle of view on display (con for me, maybe a pro for others?) I've noticed there's also a Bluetooth version of this product that allows synchronizing data from the scale to the cloud more privately, and based on my experience with this product that's common to the manufacturer, I'd recommend that as well if you don't have or want to use WiFi.
