Splitwise

Splitwise solves the problem of figuring out who owes whom when expenses are shared. You log any shared expense, assign who participated, and the app automatically calculates the balances and simplifies payments so you don't end up with a tangled web of IOUs. The platform handles currency conversion for international groups and connects to payment services to settle debts directly in the app.

It's essential for anyone managing shared costs, whether you're splitting rent with roommates, sharing a group trip, or dividing household expenses in a relationship. Unlike budgeting apps that track personal spending, Splitwise focuses purely on fairness in shared costs and making settlement simple.
