Project Overview

Complete redesign of a mobile banking application focused on simplicity and user trust. Through extensive user research and iterative design, we transformed a complex banking experience into an intuitive financial companion.

The Problem

Users found the existing app confusing and overwhelming, with 68% struggling to complete basic transactions. The complex navigation and lack of clear feedback led to high support costs ($2.3M annually) and low adoption rates among new customers (only 23% activation within first week).

The Solution

Conducted extensive user research with 200+ participants to identify pain points, then redesigned the entire experience with a focus on clarity, simplicity, and building trust through thoughtful micro-interactions. Implemented a card-based architecture, simplified navigation from 5 levels to 2, and added real-time transaction feedback.
