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
Use the Health Sync app, or a similar third-party app, to link to 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.
Syncing to Carb Manager
Once your device is pushing data, Carb Manager pulls activity minutes, calories burned, steps, weight, and blood glucose from Apple Health, and activity minutes, calories burned, and steps from Google Fit.
You may need to refer to instructions for your specific fitness device to determine how to enable syncing on the device itself.
