Expenses
Open a wallet and tap the Expenses card to see its expenses. Fen shows one year at a time, newest first.
The expense list
The header sums up the selected year, for example "You spent $1,240.00 across 18 expenses in 2026. Your top source is Hardware Store at $410.00." The top source is the merchant you spent the most with that year.
