Fitflex

– The fitness industry has rapidly evolved, yet traditional gym membership models remain inflexible and financially inefficient for many users who are unable to attend the gym regularly. This research proposes FitFlex, a smart and scalable digital fitness platform that allows users to access any partnered gym and pay only for the duration of their workout session. The system is designed to enhance user convenience, promote flexible gym access, and eliminate long-term membership obligations. FitFlex integrates QR-code authentication, real-time workout time tracking, and a secure digital payment gateway to ensure transparency and cost- effectiveness. The application architecture consists of three major stakeholders—user, gym owner, and administrator—each enabled with dedicated modules for seamless interaction and management. Users can locate nearby gyms, start workout sessions by scanning QR codes, track session history, and make automatic payments based on actual usage. Gym owners can monitor user activity and manage gym information, while the administrator oversees system security and performance.
