Splitting bills with a partner or roommate is one of those small-but-recurring frictions in life. These apps make it easy to track shared expenses, calculate who owes what each month, and settle up without awkward conversations.
Most couples argue about money not because of the money itself, but because of the tracking. A shared spreadsheet works until one of you forgets to update it. These apps give you a single source of truth that both partners can see and update. Local-first, no subscription, no bank account linking.
