PollTracker is the political app of the moment.
The must-have campaign app of this political season is not from the Romney or Obama camp--though each has its own candidate for iPhones and Android devices. In these closing weeks the app of the moment is the free PollTracker, which keeps you wired with hour-by-hour updates of polls for both local and national races.
PollTracker defaults to a "Presidential Dashboard" with a big, clean scoreboard showcasing the Romney versus Obama race nationwide, based on a weighted average of a variety of polls. Tap on "Swing States" to see the presidential race for Ohio, Virginia and 10 other key Electoral College races.
