UI Design - Let's go app

Let's go app - Let's go app (AKA. 动吧) is an app designed for runners, cyclers and walkers to track their activities, connect sport-friends and find local outdoor events. The client, a local entrepreneur in China, found my team to help him make his idea became true. I was the UI designer and product manager for this app. I didn't say I was the UX designer because at that time I didn't know much about UX design and UX roles, though I did things like user research, wireframing and prototyping for the project.
