Withings → Garmin
Syncs: Weight · Body fat · BMI · Muscle mass · Bone mass · Water % · Visceral fat · Weigh-in timestamp
Weigh-ins must come from a Withings (or Nokia) scale; the Withings API only shares data recorded by a Withings (or Nokia) scale.
SmartScaleSync is a 3rd party tool and is not affiliated with the apps listed above.

Frequently asked questions
If you can’t find what you’re looking for, email our support team!
How much does it cost?
$1.58/month ($18.99 billed annually) or $2.49 billed monthly. One membership covers every scale and destination. First time customers get a 7-day free trial, cancel anytime before you're charged.
How does it work?
Signup and start a membership. Connect at least one weight destination; then connect a weight source. After you weigh in, SmartScaleSync picks up the new weigh-in and syncs it to your weight destination(s). Some scales also provide body composition data (body fat, muscle mass, etc). We sync as much as possible: if your scale reports a metric and a destination accepts it, we send it.
How are my passwords and access tokens protected?
All passwords and access tokens are encrypted with AES-256-GCM using AWS Key Management Service; the keys live inside AWS's hardware security modules and cannot be exported, even by us. Passwords are collected in an isolated frame served from a separate domain that loads no third-party JavaScript. When possible, the credentials are used to retrieve access tokens (that are then encrypted) so that we do not need to store encrypted passwords. Your access tokens and passwords are decrypted only when needed to sync your weigh-ins or refresh an access token. When you disconnect a service from SmartScaleSync, we immediately delete the associated encrypted credentials or access tokens.
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 weigh-ins from the past?
Our subscription service will only sync weigh-ins that are recorded after your membership has started. If you would like to sync your full weigh-in history to Garmin you can purchase this separately as a one-time add-on.
Is there an app I'm supposed to download?
No! SmartScaleSync is just a website, there is no app that you need to download.
