One gym. Two connected experiences

Native apps for the people running a gym and the members training there, connected through a Node.js backend.

The project

Gym teams needed to keep track of attendance, expiring memberships and outstanding balances. For members, the product had to make fitness content and daily routines easy to reach. These different tasks shaped the product’s structure.

About these images

Manager images are original onboarding screens supplied with the project. Member screens are cropped from the original interface design board. These are historical design assets, not captures from a running app; example dates and values are not adoption or fitness results.
