Google Maps. My job requires that I go to new places almost every day, and we cover a large territory (about 22M people), so Maps is a key part of my day - though Google Calendar is a close second.
I also have about a dozen less-known apps that I use very frequently in my day job as an Audio/Video Systems Integrator. While for some things it wouldn't be my first choice, in a pinch, I could do just about everything from my phone.
