Main functions and features of Splitwise
Splitwise revolves around a few basic pillarsRecord expenses, divide them as you like, organize groups, monitor balances, and facilitate payments. Although the idea is simple, the application is quite polished and offers very practical features.

The heart of the app lies in its system for Add and manage expenses quicklyEach time someone pays for something, a new expense is created indicating the total amount, the person who paid in advance, and with whom it is shared.
The division can be done in several ways: equal distribution, percentage distribution, fixed amounts, or even individual distribution If each person has ordered something different.

This organization into groups makes it very easy to review afterwards what has been spent on a specific trip or on a season living with certain people. It is not necessary to mix expenses from different contextsand each group has its own independent balance sheet.
Some people also use groups as a kind of "event": a special dinner, a birthday party, or a festivalYou create the group, add only those who participate in that plan, and record the expenses for that day or weekend there.
