Preview before sendingYou stay in control of the first import.
No duplicatesEvery source measurement has a unique fingerprint.
Minimised dataOnly what the transfer needs.
Get started
Three steps. Then your data flows.
The setup guides you in the right order. You can inspect every detected measurement before anything is first sent to Garmin.
Create your space
Verify your email and explicitly consent to the transfer. Nothing is connected without your action.
Link your accounts
Authorise Withings, then connect Garmin. MFA is supported and your Garmin password is never stored.
Start the transfer
Choose a date, inspect the preview and confirm. Then sync on demand or automatically.
Body composition
Much more than weight.
Typical workarounds stop at weight. BodyRelay sends the six values Garmin Connect can receive whenever your Withings scale provides them.

Secure by design
Your measurements are not a product.
BodyRelay does not sell your data. The service keeps only what is needed to deliver transfers, provide support and prevent duplicates.
Encrypted at rest and in transit
Provider tokens and temporary data are encrypted before storage, with HTTPS for every exchange.
Your Garmin password is never stored
It is used only to establish the Garmin session and is not written to the database.
Delete whenever you choose
Disconnect a provider or delete your account from your space, without contacting support.
Control before the first send
The preview separates compatible and ignored measurements before anything is written to Garmin.

TroubleshootFrequently asked questions
Before you link your accounts.
Is BodyRelay affiliated with Withings or Garmin?
No. BodyRelay is an independent third-party service. Withings data is read through the official Withings API and sent to Garmin Connect.
Do I need to install an app?
No. BodyRelay works in your browser. Once the accounts are linked, automatic mode works without keeping an app open.
Can I import old weigh-ins?
Yes. Choose a start date and the measurements you want. BodyRelay shows a preview before confirmation and avoids resending the same data.
Which data is not transferred?
Garmin Connect cannot receive every Withings-specific value, including ECG, vascular age and segmental measurements. They are marked as incompatible and are not sent.
What happens if a transfer fails?
Temporary failures are retried with progressive delays. Your history clearly shows the transfer state and you can start another sync.
