Ok, as some of you already know, I've made the switch to a smart phone (Galaxy S5). The main reason was the usefulness of all the apps (applications) that can run on these phones. I want this thread to be a sounding board for the various apps that make your phone useful. I'm a utilitarian kind of person rather than social so my preference is for apps that make my life and work easier. Also like some games.
Here are the apps that I've installed so far: Flashlight, Neflix, Angry Birds, and Clinometer, Blippar (not sure I'll keep that one, though). The phone (Verizon) came with a boatload. Not sure if I'll keep them or get rid of them until I get more familiar with the phone.
