Notes on Mobile
You can add notes to your budget categories from the mobile app. To do that, tap the category then tap Details. You’ll see a section to enter a note there.
If you want to add an account or month note, you can do that on the Web App!
A note about Line Breaks
There isn’t a way to enter line breaks directly in the mobile app. You can copy multiple lines of text from another app and paste it into the Notes section of a category though and the line breaks will remain!
