First off I want to say that I absolutely hate the fact that if VeSyncFit thinks you gained weight or made negative progress, it plays this sound effect like you’re a failure. That’s an awful way to motivate people to use the scale and track their data, and there is no way to turn it off or change the sound or anything. Also, VeSyncFit seems to have difficulty registering the data coming from the scale. The first time I used it, it told me I had lost 20 pounds, then I weighed myself the next day and I had only lost roughly ten pounds but VeSyncFit didn’t seem to like that so I had to mess around with it to get the right data in. The scale is nice and works the way it should, but VeSyncFit is next to useless. Would definitely recommend to buy a different scale with a better app, if you really want the data kept on your phone/mobile device.
