RK Fitness
Mobile gym administration app for managing members, plans, payments, attendance, and daily operations
Overview
RK Fitness is a mobile gym administration app that puts everyday fitness-centre work in the hands of the people running it. Member records, subscriptions, attendance, payments, and follow-ups live in one place, making the front desk less dependent on notebooks, spreadsheets, and scattered messages.
The Challenge
Gym operations move quickly: new enquiries need a response, members need to be enrolled or renewed, trainers need accurate member information, and payment follow-ups cannot be missed. The challenge was to make those connected tasks simple on a mobile screen while still giving the administrator a clear, reliable view of the business.
My Approach
I shaped RK Fitness around the natural rhythm of a gym's front desk and administration. The app keeps the daily picture close at hand, while focused member, plan, attendance, payment, and trainer workflows make routine work easy to complete. Firebase supports the connected data layer, Zod keeps form input dependable, and the WhatsApp integration supports timely member communication.
