Tablet / Phone Apps you must have

So for those that have an android OS or iOS phone / tablet. I'm curious what you guys like to fiddle around with when you have the free time. What applications are the first things you download onto your phone/tablet that you really enjoy, or find functions well with your daily life?

-Scramble with Friends [Like Words with Friends, but more of a boggle style. Really enjoyable when i'm sitting around with a few handful of minutes to waste.]
-Pandora or Google Music [Must have muh musics!]
-Manga Watcher [Since i have so many mangas i keep up with, lets me know when the sites release them]

So what are yours?

Scramble with friends
words with friends
draw something
facebook
dropbox
facebook messenger
vlc remote

off top my head.

Why do you have Facebook AND Facebook messenger? Seems redundant IMO. But that's beside the point. My must-haves are as follows:

Facebook
eBay
Craigslist
Plants vs. Zombies
Lux Touch
UNO
Phase 10
Solitaire
My mobile banking app

And yeah that's the essentials. I've got a LOT of games on here, but most of them are just pointless ways to kill time. Nothing essential.

Facebook is good for Facebook but not chat. Messenger is built solely for chat and is awesome.
