I think they would be much more attraction and activities when they have maybe a mobile app and get feature in popular stores like Google playstore, IoS and the likes. I have seen the UI and I think they would become popular in short time if the UX is cool too
I agree with you mobile applications are much more handy for playing games and appreciating BApps, for an app to be widely used it needs to available in the app store and accessible for all users, I have a conviction that the team are considering launching the app soon as this would be a great service to the community.
