We're working on direct integration with Samsung devices but in the meantime, check below to see if you can connect your Samsung device via a 3rd party fitness app to Google Fit or Apple Health as an intermediary.
Samsung Devices and Android
Download the Health Sync app from the Play Store, open it, and link it to your Google Fit app. Please disable direct activity tracking in Google Fit so that only your Samsung data writes to Google Fit.
Once you've connected your Samsung to Google Fit, link to Carb Manager by going to Settings > Fitness Device Links and toggling Connect with Google Fit to On.
Once your device is pushing data, Carb Manager pulls activity minutes, calories burned, and steps from Google Fit.
Samsung Devices and iOS
First, check to see if your device is compatible with the Apple Health app. If it isn't compatible, search for a third-party app that will link to Apple Health.
Once you've connected your fitness device to Apple Health, link to Carb Manager by going to Settings > Fitness Device Links and toggling Connect with Apple Health to On.
Once your device is pushing data, Carb Manager pulls activity minutes, calories burned, steps, weight, and blood glucose from Apple Health.
