Just install the app, enter your name, height and gender, and you're ready to step aboard and start weighing. The Eufy Smart Scale C1 is refreshingly fast and easy to set up. We’ve put the latest smart scales from Garmin, Withings and Eufy through their paces, testing how easy they are to use and initially set up, if their readings are accurate and consistent, how they sync with their adjoining apps, and to see if the information they present to us gives us a clear picture of our health. Together with the best fitness trackers or best smartwatches from these ecosystems, you'll get a far more complete picture of your health than you would using either device alone. Most can connect to an app, via Wi-Fi or Bluetooth, and add your measurements to ecosystems like Fitbit, Google Health Connect, or Garmin Connect automatically. Most of them give you your stats simply by you stepping on them, once you've set them up. The best part of all that is that it’s very easy to learn how to use a smart scale. The electrical current travels through your fat, muscle, and bone at different speeds due to the different tissue densities, and because the current records the speed at which it travels, it can tell you how much of each you have in your body. Smart scales utilize BIA by sending a current of electricity from your feet through to your body.

This is usually done via a process called biometric impedance analysis, or BIA.
