On iOS devices, the Carb Manager app badge is a feature that can display either your current remaining carbs or your current daily carb count. The selected amount appears as a red badge on the app's home screen icon.
To enable this feature, go to Settings > App Badge, and select one of the following options:
- Remaining. Shows how many carbs you have remaining for the day.
- Consumed. Shows how many carbs you've eaten so far today.
