The Track Spends tool allows groups like roommates or families to easily track shared expenses through SMS. Users create an online account and add group members with their mobile numbers. Individuals can then SMS expenses like bills, meals, or purchases to the Track Spends number and have them recorded under their name. At any time, group members can view a total or itemized list of all expenses or filter by an individual to see what they have contributed. The tool aims to simplify the difficult process of expense tracking between groups living or spending time together.
