We've released an updated version of our NFL Tracker. It is definetly a beta version as we've been unable to test the watch a game feature on a live game (since the games only happen once a week).
We still have a few known bugs but most of the app looks to be working good.
Plus, dont forget to try our MLB Tracker which is a bit more stable and will give you an idea of what the NFL Tracker watch game feature will be like.
Also - if you like either program and are experienced in generating traffic / promoting websites please contact us -- we have a lot to learn in that area
