If you eat the same meal often, then you can create a custom saved meal making it faster to log this meal the next time you eat it.
To create a saved meal from any meal on your daily log:
Tap the ... button next to the meal name
Tap "Save Meal"
Rename your meal as necessary
Tap the checkmark in the top right corner when done.
This will create a copy of this meal in your Saved Meals for fast logging moving forward.
