VeSync app setup
The VeSync app is continually being improved and may change over time. If there are any differences, follow the in-app instructions.
- To download the VeSync app, scan the QR code or search “VeSync” in the Apple App Store or Google Play Store.
- Open the VeSync app. If you already have an account, tap Log in. To create a new account, tap Sign up.
- Make sure to enable Bluetooth permission for the app and turn on Bluetooth. For Android users, allow the app to access nearby devices in your phone settings.
- Tap + in the VeSync app.
- Select your smart scale from the device list.
- Follow the in-app instructions to complete setup.
Using the smart scale
Placing the scale on soft surfaces such as shaggy carpet may cause inaccurate measurements or tipping. If necessary, this scale can be used on low-pile carpet with a fiber length of 0.4 inches / 10 mm or less. If the scale cannot be turned on or the battery is low, it needs to be charged. Charging the scale may take up to 3 hours.
- For the best results, place the scale on a hard, flat surface.
- Step on the scale, then step off. Wait for the screen to display “0.0” before using.
- Place dry, bare feet on the scale’s conductive areas. Continue standing on the scale, then step off when the display shows “BYE”. If your smart scale is connected to the VeSync app, additional metrics that are not selected for display on the scale will show in the app.
PreciSync technology
The smart fitness scale uses PreciSync auto-recognition technology to select an existing user profile based on weight, an ideal feature for a household with multiple users. To use this function, you must first connect the scale to your VeSync account and sync user information with the scale.
How PreciSync works
The scale will compare the user’s current weight with all user profiles synced to the scale.
- If only one user profile is within 6.5 lb of the current weight, it will be automatically stored under that user’s profile.
- If multiple user profiles are within 6.5 lb of the current weight, the display will prompt the user to tap their right foot to select a user profile.
- If no user is within 6.5 lb of the current weight, the weight will be automatically stored as a guest profile without prompting the user to select a profile.
Maintenance
Clearing the smart scale
If the scale has been moved or flipped upside down, it must be cleared to ensure accurate results.
- Place the scale on a hard, flat surface.
- Step on the scale until digits appear on the display, then step off.
- Wait until the scale displays “0.0”.
Cleaning the smart scale
- Use a slightly damp cloth to clean the surface of the scale, followed by a soft, dry cloth to wipe away any remaining moisture.
- Do not use chemical or abrasive cleaning agents to clean the scale.
Troubleshooting
The scale doesn’t turn on
- Restart the scale by using a safety pin or paper clip to press the “Restart” button near the charging port.
- Charge the scale with the provided charging cable for 3 hours.
