Why Combine Withings with Your Wearable
Wearable devices like Apple Watch, Garmin, Polar, and Oura Ring track your activity, sleep, and heart rate — but they don't measure body composition directly. A Withings smart scale fills that gap by providing accurate weight, body fat, and muscle mass data. Vitalstat brings everything together so you can see how your training, sleep, and nutrition affect your body composition over time.
Privacy & Security
Withings connection uses OAuth 2.0 for secure authorization. Your Withings account credentials are never stored by Vitalstat. OAuth tokens are stored in your device's encrypted Keychain. Body composition data from Withings is cached locally on your device and never uploaded to external servers.
