Fintech Mobile App

Transforming complex banking technology into seamless, user-friendly experiences.

ACO Bank redesigned mobile app homepage with clear account overview and quick actions ACO Bank simplified payment interface with improved accessibility ACO Bank security and fraud prevention screen with user-friendly controls

Context

Advanced technology, smartphones, and digital banking began changing the game over 20 years ago; however, back then, they were not accessible to everyone.

Today, in our fast-paced world, most people know how to use online banking but they don't want to waste time, everyone's in a rush. Meanwhile, older generations often feel left behind, saying their minds aren't built for the complexity of modern technology.

Iteration

ACO Bank low-fidelity wireframes showing homepage, payments, and navigation structure
Research

Guerrilla user testing

Usability testing was conducted with 20 participants representing diverse age groups and digital proficiency levels, validating that the wireframes were intuitive for both experienced and first-time users.

Research

Some feedback

  • Users over 50 struggled to locate quick-access actions
  • The dashboard layout felt too busy at first look
  • Users were unsure about security prompts
ACO Bank usability testing results and iteration insights from 20 participants

During the iteration phase, the screens were refined based on insights gathered from usability testing. These improvements reflect direct user feedback and aim to enhance clarity, efficiency, and overall user experience.

Redesigning the homepage for clarity, speed, and better decision-making

  • Clear account overview
  • Quick forecast access
  • Simplified shortcuts
  • Personalised promotions
  • Optimised navigation

Faster and clearer credit card payments

The "Make a payment" and "Set up a direct debit" buttons were made larger to improve visibility and make key actions easier to find. This change supports quicker payments and helps users take action with more confidence.

Faster access to customer support

The "Request a call" and "Start chat" buttons were added to the first Help screen, allowing users to quickly find answers or contact support without navigating through multiple pages.

Improving visibility and ease of payments

Buttons were optimised and font sizes increased to improve readability and make the "Pay someone" screen easier to navigate.

Consolidating payment actions for faster access

The "Pay a bill or company" and "Send a money request" buttons were added, along with a "More actions" section at the bottom of the screen.

Updating security & fraud screen

Reducing friction and increase user confidence in fraud prevention and account safety.

Reflection

Working on this project on my own helped me understand why it's important to think about rules and limitations early on.

User testing showed me that my first ideas were not always correct and that small improvements can make the experience easier for users.
