While we do not have a direct connection with Garmin, you can indirectly connect Withings App with Garmin via a third-party app, such as Health Connect. Here's how:

Note: Make sure that Health Connect is connected to Withings App first.

1. Open Health Connect
2. Go to the Settings tab.
3. Go to My Apps & Devices.
4. Select Garmin Connect.
5. Tap Connect.
6. Follow the on-screen instructions.
7. Now, the data collected by Garmin Connect will be available in Withings App via Health Connect's data.
