These are my must-haves:
-If you like Pandora, give Songza a shot. It has what it calls a "music concierge" that fits playlists to what you're most likely doing at any time of day. It's a pretty neat concept. Not as vast a library as Pandora, but it's still pretty good.
-I love my tech, so I have the TWiT app to stream video or catch up on podcasts.
-Bleacher Report's Team Stream...love all the updates on all my favorite teams and leagues.
-Flipboard is best on the iPad, but it does well on the iPhone too.
-Pocket...to catch articles, video or pictures I may not have time to read or see right away. Before I got Pocket, I don't know how many articles I never got around to reading because I couldn't read it at that moment. Pocket makes it easy and I like the layout of the article in the app.
-Buzzfeed...I need general internet randomness in one place. They have it.
-Offical Weight Watchers app...unbelievably helpful in my battle with the bulge.
-Other basics...Facebook, Twitter, Starbucks, The Weather Channel & Tapatalk.
So that's just (more than) a few. I 'd strongly recommend Songza, Pocket and Team Stream. They're each pretty nice at what they do.
