A new streetcar arrival app for iPhone called Pocket Rocket can see into the future to determine your fastest route, according to an article on blogTO. A clean interface and the ability to estimate arrival times at future stops makes this the most advanced mobile app yet for predicting public transit travel times in Toronto. Costing a bit less than a TTC token, it sure beats texting for next vehicle arrival information or using the TTC Trip Planner for accuracy and peace of mind when standing out in the cold.
