Management app for golf games

It is a cross-platform mobile application for creating and managing golf club games. It caters to two primary types of users: hosts and players. Hosts can create, cancel, start, and end golf rounds and invite players to participate. On the other hand, players can confirm or reject invitations to join the rounds and provide feedback after completing games. The application supports invitations for both registered and unregistered users. Unregistered users receive notifications about invitations via email. Once they register, they will gain access to the details of their rounds. Moreover, users can determine their role during registration by entering and confirming a registration code. Users can also log in using their Google or Facebook accounts. The application features automated notifications sent to users via phone or email for specific events or upon request of other users.
