'Should I Run?' is an iPhone app for the daily commuter. Using real-time transit data, we tell you if you need to hustle to make the next train, or can just take it easy. 'Should I Run?' takes the guesswork out of your commute with a few quick taps.

We recognize that transit users don't want to miss a train they could have made. But at the same time it's hard to quickly get access to all of the information needed to make a train.
