You can group your spending into custom categories on the Blackbullion app.
To do this, head to the ‘Spending Summary’ tab and scroll down until you see a button that reads ‘Create Custom Category’ - click this. This will take you to a screen with all your custom categories. There will be a banner which reads ‘Create New Category’.
If you click this, you will be led to create a custom category. From here you can choose a name for your category, an icon to represent the category and a colour for this icon.
