FitnessHub is a dedicated mobile application designed for members of gyms that utilize the GymOS system. This app streamlines the gym experience by allowing users to effortlessly book classes, manage their reservations, and access resources provided by their gym. The interface is user-friendly, making it easy to navigate through various functions tailored to enhance the overall fitness journey. Users can also manage key aspects of their accounts, although the specific features available may vary depending on the gym's offerings.

The application is not intended for self-sign-up; instead, gym members receive login credentials created by their respective facilities. This ensures that access is limited to authorized users only. While FitnessHub offers essential functionalities for gym members, any technical support is facilitated through the gym, which can escalate issues to the GymOS team if necessary. Overall, FitnessHub serves as a vital tool for managing gym activities and enhancing member engagement.
