Zwift does natively integrate with both Fitbit and Withings - but these connections are known to be flakey. If you're looking for a more reliable way to sync your weight to Zwift, SmartScaleSync can help.

To set things up, create a SmartScaleSync account, then connect a weight source, and then connect Zwift as a weight destination.

Going forwards, if you start a SmartScaleSync subscription ($18.99/year or $2.49/month), SmartScaleSync will automatically upload your completed weigh-ins to your Zwift account. All new users have a 7-day money back gaurantee.
