Designing a financial management smartphone app for users with mixed literacies

India is experiencing a radical technology transformation as smartphone ownership and data usage has skyrocketed, with penetration even into low-income areas in urban India. This provides an opportunity to design more inclusive services on the smartphone. This paper describes the design of SalaPrayana, a financial management application for end-users with a range of literacies. Designing apps for a target audience with a range of literacies introduces tensions between visual interface design and the complexity of information conveyed. We present our designs and discuss some of these challenges. We found we could communicate familiar information, such as payment history, easily to all users, but other more complex information such as 'Loan Status' remained challenging.
