So, you think you know football? How the action will unfold on the field? What players will outperform the others? A new app from Redwood City, Calif. start-up WinView, Inc. which synchronizes live TV with mobile provides users with a chance to showcase their pigskin knowledge and prognostication skills to win cash prizes while facilitating interaction during live-game viewing. The Super Bowl LI matchup between the New England Patriots and Atlanta Falcons culminates the app’s rookie run with pro and college football, which has drawn some 100,000 downloads this past season, and has attracted PepsiCo. as a sponsor.
