I designed an interactive high-fidelity prototype in Figma for a Finnish mobile payment app, focusing on improving usability and visual consistency. The prototype allows realistic user interactions to test and refine design decisions.
I created year- and month-level transaction graphs so users can view their sent payments for each contact over time, and added a payment categorization feature to help them understand what types of expenses each payment relates to.
