Why aren't debts counted in expenses and income?

Taking or repaying a debt is not quite a transaction: on its own it does not change your balance.

Say you borrow 100 (income +100) and later repay it (expense −100). Total income and expenses each moved by 100, while your balance was not affected at all.

That is why debts are counted only in the “With debts” balance — so you always know how much money you actually have on hand right now. This balance is available on iPhone only; Android does not have it.

To see it on iPhone, tap the word “Balance” on the Summary: the “With debts” line opens below it. The line includes debts with the “Show on Summary” switch on; if there are none or they add up to zero, the line is hidden. More in How are debts counted in the balance?
