Zenpass is a platform that allows users to access any gym at any time with a prepaid pass, addressing issues with expensive subscriptions, inconvenient hours, and lack of freedom that users and gyms currently face. The platform aims to fix these problems through a single solution that is easier, cheaper, and unrestricted for users while providing more users, profits, and visibility for gyms. It works by allowing users to buy coins and book exercises, and also features a social community and advertising opportunities for both users and gyms.
