The Bill Divider app lets you manage and split bills with other people. You can add a tip (service) and divide it equally with a specified number of people, or you can enter individual information for each person, and the app will calculate how much each of you has to pay. You can then save records to your device to review them later. If necessary, you can choose a currency to work with each bill.
Additionally, you can create custom categories to keep track of your records more easily.
