Mercury Mobile App
Mercury Energy has developed a mobile app that allows their customers to easily manage their bills, energy usage and much more. The team has been working on this project for over six months and they have created something amazing. In fact, the app was recognized as a finalist in the 2023 BestAwards.
The Brief
Mercury Energy needed a complete digital overhaul — marketing site, chatbot, web app, and mobile app, all under one project. A significant undertaking with a lot of moving parts.
My Role
UX and UI design for the mobile app, working as a contractor embedded within the Catch Design team.
Approach
The mobile team's priority was consistency. We built a design system first — establishing the foundations before a single screen was designed. From there, we developed experience patterns to keep the UX coherent across the app, no matter how many hands were involved.
Deliverables
- UX design
- UI design
- Mobile design system
- Experience patterns and component library
Outcome
A polished mobile app delivered as part of one of the larger digital projects in the energy sector. The design system built during this project gave the broader team a solid foundation to build on well beyond launch.
