Which platforms do we support today?

SmartScaleSync is a 3rd party tool and is not affiliated with the apps listed below.

Weight Sources

Withings will share all data collected by your scale with SmartScaleSync (weight, body fat, bone mass, muscle mass, water %). You must have a Withings scale to use Withings as a source - the Withings API will only share weighins that come from a Withings scale.

Weight Destinations

SmartScaleSync can upload weight, body fat, BMI, and a weighin timestamp to Fitbit.

Frequently asked questions

If you can’t find what you’re looking for, email our support team!

    • How does it work?

      Signup and start a membership. Connect a weight source and at least one weight destination. When SmartScaleSync receives a notification from your weight source, we will sync the weighin to your weight destination(s).

    • Can you add support for a scale or missing destination?

      You can submit a scale request here, and you can submit a destination request here. Thank you for your submissions! They will help direct product development.

    • Do you sync weighins from the past?

      Our subscription service will only sync weighins that are recorded after your membership has started. If you would like to sync your full weighin history to Garmin you can purchase this separately for $34.99 (one time non-refundable charge).

    • Is there an app I'm supposed to download?

      No! SmartScaleSync is just a website, there is no app that you need to download.
