Sumally Pocket, operated by Sumally Inc., is a storage service that lets users store their belongings and manage them from a smartphone. I was responsible for designing and implementing the iOS app for the service's launch.

Making the app feel pleasant to use was a priority throughout development. I paid close attention to performance, animations, and sound effects to make everyday interactions feel smooth and enjoyable.

After the iOS launch, I continued to contribute to the service through service design for new features and development support for the web and Android versions.

Key contributions

Building the iOS app for the service launch

I worked across iOS development, from architecture design to implementation. We addressed technical and interaction challenges and delivered the app on schedule in approximately six months.

Refining performance and interactions

I focused on performance improvements and interaction design and implementation to make the app feel good to use. This included refining responsiveness, animations, and sound effects, with attention to the small details that shape the overall experience.

Service design and development support after launch

After the iOS release, I became involved in service design for new features. I also supported development of the web and Android versions, contributing to the service's expansion to other platforms.
