From housing bills and utility bills to bar taps, taxi fares, and movie tickets, Sally and her roommates constantly struggle to figure out how much each person owes another in total. Between her and her roommates, they find themselves either not remembering an amount of debt, disputing an amount of debt, or disputing a debt completely. One of Sally's roommates, Jackie, had once tried to take up the task of keeping track of everyone's debt with a personal finance application on her iPhone, but this task proved to not only be too cumbersome for not only Jackie, but she found it impossible to track all of the roommates down at once to settle debts since they all have different schedules (and don't want to settle debts when they're going out!). With her busy schedule, Sally would really love to be able to have a system that allows her and her roommates to keep track of their mutual debt, dispute any debts that are questionable, and review all of their transactions at the end of the month when they pay their bills. Notably, Sally would like to be able to easily add new transactions (when she foots the dinner bill for a group of friends), easily view all transactions posted, and also flag a bad post if she wants to dispute an faulty transaction.

Figure 6 shows the "settle dispute" pop-up menu. In this pop-up menu, there is a "new amount" field that is defaulted to $0.00. This default has been chosen to make it easy for users to accept disputes (clearing the debt). This type of menu also makes it easy for the two users to agree on a new amount of the debt if they choose so. if the new amount is set to $0.00, the debt will be automatically deleted on both of the user's accounts.Now, draw your attention to Figure 2.
