Mobile App _ Fitness Tracker

Roylance my client is gym owner, He owns over 25 franchises in the state of New York. The gym has over 3,000 fitness freaks who love to track their fitness goal.
The epic is, most of them sharing their daily activities with their mates and doctors for better advise. Gym clients were using different apps for activity tracking and sharing those activities on another app. Also, they love to share sometimes their states with Roylance.
Roylance picked the problem as the use of multiple apps is frustrating and we should come up with our own gym app for personal branding and make it easy to use for our clients in one and only one standalone app servicing the multiple things.
Here is the dashboard for this app.
