One year ago today Navigon’s Mobile Navigator debuted on the App Store. It’s arguably the best turn by turn guidance app available and the one that I consistently recommend. And it’s even easier to recommend it when they do something awesome like slash their prices by half across the board. That’s right, you can get any of Navigon’s Mobile Navigator apps or add-ins half off until August 15th.

The best GPS app on iPhone just got a little bit better. Navigon’s MobileNavigator is already an amazing GPS routing app with its voice prompted directions, smoothly animated maps and excellent everything-I-can-think-of, but Today they’ve added Traffic Live for North America.
