Once you have created your group with friends or family, click the 'Add expense' button on the group's main screen.
On the next screen, you will see a list of all your transactions in DolarApp. There, you will have to tap the green button with the "+" icon.
You need to fill in all the requested information:
Description: a brief explanation/name for the manual expense.
Amount: the total amount you paid.
Currency: select one of the available currencies (USD, MXN, ARS, COP, BRL).
After completing the manual expense information, you can specify how to split the account with the group members. That's it!
