Fairly learns them. A group expense app should know that the chat goes quiet when someone asks “so who owes what?” Fairly learns who always pays, what's never shared, when you settle. Every learned rule is visible in the group and editable. The personalization is inspectable, never hidden.

One clean sweep. Everyone captures as you go — even offline in a restaurant basement. When the trip ends, one sweep checks for missing expenses, flags duplicates, converts currencies at the day's rate, and simplifies who pays whom into a few transfers. It stops to ask at every step that matters.
