Open event project provides a platform for managing all the activities in an event. It has different mobile applications for both attendees and organizers. My proposal aims at enhancing the attendee app by providing more event information, integrating more payment methods and improving the registration process. In the current state of the app, all features are implemented according to the previous version of eventyay server. My goal is to integrate new features which are implemented (or will implement during GSoC) in the frontend (https://next.eventyay.com) and the server (https://api.eventyay.com/).
