HouseMart is a mobile application that allows roommates to buy, sell, and track surplus household items in one centralized place, rather than through text message chains. It underwent user testing, and testers gave high ratings to the account creation, house creation, and viewing and buying items features, but identified issues like the inability to change houses or buy your own items. Based on feedback, the MVP2 version added the ability to settle debts between roommates and set buy/delete permissions, as well as ease-of-use features like displaying item costs and owners.
