Reducing the stress of Toronto commuters

PRESTO is a transit fare card used mainly in the Greater Toronto Area. In the app, users can check the balance of their cards, add funds, and manage other settings. These features help users commute daily without going to a station or a ticket machine. As a daily user of the Presto app, I saw an opportunity to improve its confusing and frustrating UX and UI design so I decided to redesign the app as a personal project.

My Role

For this project, I worked as a UX/UI designer and completed the whole process from research to prototyping.

🔍 Problem

Design audit and app store reviews revealed that the app had confusing navigation and lacked user-friendly UI. This could be a challenge especially for an app targeting commuters on the go.

💡 Solution

My solutions were making user flow intuitive by organizing the content, creating simple and easy to navigate interface, and prioritizing accessibility in designs.

ℹ️ Information Architecture

Listing all existing features and organizing them using an information architecture allowed me to see the flow in a bigger picture.

✏️ Low-fidelity Wireframe

Based on the flow created with IA, wireframes dictate contents and placement on each screen.

🎨 UI Style Guide

🔨 High-fidelity Mockup

While utilizing the company’s existing brand identity, my task here was to assign colours to each elements that ensured accessibility.

Sign In / Sign Up Flow

The key here was to make the registration process, which could be daunting for users, as easy and as pleasant as possible. By providing clear call to action on each step, it reduces users’ cognitive load.

Load Funds Flow

One of the main features of the app was Load Funds. Knowing the importance of reducing the frictions in this flow, I spent a lot of time revising in detail. Observing how a user interact with it and think about it helped me improve the design.

✨ Design Comparison

Conclusion

This mobile app redesign project successfully improved the user experience by organizing the flow, simplifying the interface, and maintaining accessibility throughout the screens. Frequent user testing ensured that the design is intuitive and functional.
