With a lot of negative comments in your thread especially with the UI and UX of the website you promote, better consider taking every posts as a recommendation to improve you and your platform. Also, I would like to recommend that you would make an API that connects to your data (preferably the median calculation of most famous odds platforms which many had wished you consider adding) then make a widget on smartphones that connects to that API. You need to make an app ofcourse but it wouldn't be that hard if you only focused in having a widget and internet connection permissions. After making an app, you need to run in three phases: Alpha Test, Beta Test, then the official release.
