The Beurer BF800 is one of 3 app enabled sets of bathroom scales I have at home at the moment. The Withings Smart Body Analyzer - Black
along with the Medisana BS 430 Connect Body Analysis Scale with Bluetooth
. I haven't finished trying the Medisana scales yet; but have all three side by side as I write the review. The Beurer sits in the middle in terms of price; along with features. The Medisana is considerably cheaper than either the Withings or Beurer BF800 here.
The scales come in a very multilingual box; and boast of numerous certifications from the german TUV testing agency. You can use these scales stand alone and there is a bright easy to read LCD screen on the scales to let you use them in that way; but if you do you are spending a lot of money for the glossy look. Downloading the app from the App Store I was immediately impressed with one feature Beurer has that no other health tracking app I have used before had - you don't have to send your data to the cloud and risk that the TUV security certificate on the box ever gets broken; you can keep it safe on your phone.
Connecting the scales to the phone requires you to press a button on the base and hold your phone running the app near the scales; the scales are presumably using Bluetooth 4 to connect which saves them from pairing to your phone via the bluetooth menu. Once that is done taking a reading to the scales a question of standing on them with the app open and the BF800 measure your weight (up-to 180kg which is about 28stones for the imperialists.) After reading your weight it also quickly reads Body Fat %, Water % and Muscle % of your weight through your feet (you need to take your socks off.) The reading is very quick; much more so than the withings. The app will show you the last reading along with a chart and raw data display. If you are traveling away from home you can also manually enter a weight reading. The app itself does look a bit simple compared to the colorful charts on the Withings app; though the data they show is the same.
The scales do lack some functionality compared to the withings; which can also measure the CO2 content of the atmosphere in your home - though I'm not sure how useful that is. The scales give a similar reading to the other 2 I currently have. I really like that you can choose to upload your data to the cloud or not which gives you extra privacy choices. I have the white scales and they look quite nice; if you want to use them without the app the screen is far better than the one on the Withings.
Between the Withings and the Beurer the basic function of taking weight measurements is identical. Bearer's app has additional abilities for movement and blood pressure monitoring so there are more devices out there to round out measuring your health. The app is a bit simple; but the privacy benefit allowed by not sharing your details wins it back to 4 stars for me.
