Why we love it: With its accelerometer, the iPhone has always been well-suited for flight simulators. And for a long time, the king of those was an app called FAST. In December, however, HAWX changed that for good. The controls are the same, but while FAST was based on short half-minute missions, HAWX introduced long-form missions that could take upwards of 15-20 minutes and evolve an engrossing storyline mid-flight. Consider the bar permanently raised.
