Reszone

Designing the Reszone fitness app.

Five Reszone app screens on floating phones.

A device that tracks you. An app that tells you what to do with it.

Reszone is a fitness device paired with an app. It monitors workouts and health, then recommends exercises based on what it sees. My job was to design the app, so the data from the device turned into something people would actually use. Designed end to end, then handed off cleanly to developers.

UI Design - End to End
Timeline:
15 days

They had a UI. It just wasn't the one.

The team came with an older UI, and it wasn't working. I said so, explained why, and we agreed to start fresh. Better to say it on day one than to polish something I didn't believe in.

The screens that turn data into a next step

A fitness device collects a lot about you, and numbers on their own don't make anyone want to work out. The job of these screens was to take what the device monitors, from workouts to health, and turn it into something clear, then point to what to do next: the exercises recommended for that person. I designed every screen end to end in 15 days, with no research phase and one sole designer, so each decision had to earn its place. What you see here is the version that went to the developers: clean, consistent, and built so the data stays easy to read and the next step stays obvious.

What 15 Days and Zero Research Taught Me

No research doesn't mean no thinking.

There was no time or budget for user research, so I leaned on what I could do: competitive analysis, and a clear sense of what a person wants from a fitness app, which is to see their progress and know what to do next. Two platforms in 15 days meant picking what deserved attention and letting the rest wait. What I'd do with more time is talk to the people wearing the device. That is the honest gap.
