Ryazza is a mobile and web app that helps organize group trips, experiences, and activities. It caters not only to individuals planning trips with friends but also to professional organizers, tour guides, and travel agencies, as well as small tour operators. With Ryazza, users can describe their trip idea, invite friends, collect money, provide all the necessary trip information, and communicate with trip participants. Trip participants, whether casual friends or organized groups, can easily join the trip, make advance payments, and stay informed thanks to instant messages that the organizer can send. The app serves a broad group of people, ranging from millennials to seniors who are taking part in trips organized through a travel agency. Creating an easy-to-use and intuitive UI was crucial to ensure a seamless experience for all users.
