The first stage of the game tracker app is nearly finished in development. Admin users can add teams, set up sports leagues and seasons, and schedule matches. The second stage is to implement the prediction algorithms, and the third stage is to present a public view of those algorithms.
The hardest part of programming this part of the app is trying to design a responsive html view of the match schedule. Especially on the editor side. There's a lot going on with lots of teams, dates, and scores, so making it easy to use on a mobile device is quite the challenge.
