Watching live sports can get very emotional, even for the fans sitting in front of their TVs. That’s why Fanmode, a London-based startup, is developing an app to help the audience express their feelings and be heard. The company even has plans to integrate the app into wearables for easier reaction tracking. By aggregating real-time sentiment data during live sport events, Fanmode’s platform would be transformed into a virtual arena, where all fans are connected to the action. It could also potentially open up a feedback loop between the fans and their teams, essentially revolutionizing the way we watch live sports.
