Zwift does natively integrate with both Fitbit and Withings - but these connections are known to be flakey, and Google has announced it is shutting down the Fitbit API. 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 ($1.58/month billed annually at $18.99, or $2.49 billed monthly), SmartScaleSync will automatically upload your completed weigh-ins to your Zwift account. First time customers get a 7-day free trial, cancel anytime before you're charged.

Please note: Zwift does not allow your weight to be updated while you are in an event.
