VeSync App Setup
1. To download the VeSync app, scan the QR code or search
“VeSync” in the Apple App Store®or Google Play Store.
Note: Due to app updates and improvements, the VeSync app may be slightly
different than shown in the manual. In case of any differences, follow the in-app
instructions.
Note:
• For Android™ users, you may need to select Allow to use VeSync.
Note: You must create your own VeSync account to use third-party
services and products. These will not work with a guest account. With a
VeSync account, you can also allow your family and friends to use your
smart tness scale.
2. Open the VeSync app. If you already have an account, tap
Log In. To create a new account, tap Sign Up.

12
Note: You can change the name and icon at any time in the smart
tness scale settings.
3. Make sure your phone has Bluetooth®turned on.
4. Tap + in the VeSync app and select your smart tness scale.
5. Follow the in-app instructions to connect to your smart tness
scale.
If you are a new user, you will need to enter physical information
before weighing yourself for the rst time so the scale can calculate
your body metrics. Follow the in-app instructions to create a user
prole.
Note:
• Entering inaccurate information will make the scale’s measurements less
accurate.
• If you don’t identify with the available gender options, or are unsure, pick
the option that you think best physically matches you. This choice is
used for physical measurements, such as body fat percentages.
• Children under 3 years of age cannot measure body metrics other than
weight.
• Minors will need a guardian’s consent to create a VeSync account.

Using the Smart Scale
1. Place the scale on a hard, at surface.
Note:
• Placing on soft surfaces such as shaggy carpet may cause inaccurate
measurements or tipping.
• The scale can be used on low-pile carpet with a ber length 0.4 inches /
10 mm or less.
2. Step on the scale, then step off. Wait for the LED screen to
display “0.0” before using.
3. Place dry, bare feet on the scale’s conductive areas. Stand on
the scale until the display ashes several times, showing your
nal measurement. If your smart scale is connected to the
VeSync app, additional results (such as BMI, body fat, etc.) will
show in the app.
Note:
• To switch between pounds (lb), kilograms (kg), and stone (st), open the
VeSync app and select the weight unit in the Device Settings menu. To
see measurements besides weight, you must connect the scale to the
VeSync app (see page 11).
• Turning on Zero-Current Mode in the VeSync app will turn off the scale’s
electrical current and will only provide measurements for weight and
BMI. This mode can be helpful for users who are pregnant or who have
implanted medical devices, such as pacemakers.
• To measure your baby or pet, turn on Baby Mode and follow the in-
app instructions for weighing. Baby Mode will not measure other body
metrics and will only measure weight and BMI.

the rst time, remove the plastic insulator strip from the battery
compartment.

The smart scale doesn’t connect with the VeSync app.
• Make sure your phone’s operating system is running on iOS®10.0+ or
Android 5.0+.
• Close and relaunch the VeSync app. Make sure you’re using the latest
version.
• Make sure your phone has Bluetooth turned on. For Android users,
make sure your Location is turned on as well.
• Make sure your scale and phone are within 30 ft / 10 m of each other.
• Make sure the scale is not currently connected to any other phone or

My scale will only measure my weight, not my other metrics.
• Set up your smart scale in the VeSync app. Your weight will show on
the scale display, and your weight, and more results will show on the
app.
• If you’re wearing shoes or socks, the scale cannot measure health
metrics such as body fat. Step on the scale with bare feet. [Figure 2.1]
• Make sure to place your feet on the scale’s conductive areas.
[Figure 2.2]
• Make sure Bluetooth is turned on.
• Check if Zero-Current Mode is on. If it is, the smart tness scale will
provide measurements for only weight and BMI, not other metrics.
Note: If the scale has errors on the display, will not turn off automatically, or
has a problem not listed here, try removing the batteries for 3 seconds, then
replacing them. If the problem is not resolved, replace the batteries with new
ones.
If you still need help, please contact Customer Support (see page 24).
