SmartScaleSync can sync your Withings scale with Garmin! We can retrieve your weight, body fat, BMI, muscle mass, bone mass, water % and visceral fat index from Withings and upload them to Garmin, along with the timestamp of the weigh-in. We can also sync blood pressure readings from Withings to Garmin.

The same membership can also send your weigh-ins to Strava, Zwift, Intervals.icu and more. The table below lists each destination and what we can send to it from Withings.

How to set it up

  1. Create a SmartScaleSync account and open the settings page.
  2. Connect Garmin, Strava, Zwift, Intervals.icu or any of your other apps as weight destinations. You can connect as many as you like.
  3. Choose Withings as your weight source, click "Connect to Withings" and approve the connection on the Withings site.
  4. If you start a SmartScaleSync membership ($1.58/month billed annually at $18.99, or $2.49 billed monthly), then anytime you step on the scale Withings will send us a notification and this will trigger a sync immediately.

Things to know

  • You must have a Withings (or Nokia) scale to use Withings as a source. The Withings API will only share weigh-ins that come from a Withings (or Nokia) scale.
