About the project:
Developing a mobile application targeted at users interested in sports betting. The client is from the USA. It supports a vast variety of sports, from American football to golf and racing. Here’s a list of sports leagues: NFL (American football), NBA (basketball), MLB (baseball), NHL (ice hockey), NCAAF (college football), NCAAB (college basketball), MMA (mixed martial arts), PGA (golf), NASCAR (stock car racing league). Users will be able, as in most standard applications, to register (create their unique profile), and track real-time stats on games, namely, various betting odds for a wide variety of sportsbooks. At the same time, a user can make their own virtual bets on specific games within the application, see the result of their bets at the end of the game, keep statistics, and monitor the bets of other users (follow them). In addition, there will be a section with articles where users will be able to read sports news and add them to their bookmarks. There’s a social component that is planned but yet not fully developed. The client has something like a social network in mind.
