Keeping track of expenses

I wanted to share a bit about how my man and I know where our money goes.

 We have a list which has 7 categories.  They are the expenses that are not fixed.  We spend the same on our phone bills, and insurance every month, however we spend over and under budget on groceries and doctor's appointments.  The irregular categories include
-Groceries
-Anna's entertainment (lunch out, coffee, beers etc.)
-Dominik's entertainment
-Music (Dominik's instrument budget)
-Art (Anna's art supply budget)
-Un-categorized expenses
-Olive Green Anna expenses

Neither of us have a smart phone yet, so we keep track on paper.

Where do you keep track of your spending? Do you use an app?
