50 Android apps you must install before the world ends

So you’re new to Android, eh? Welcome to the club, we think you’ve made a great decision! In the event you haven’t already filled your phone or tablet with a slew of Android apps and games, we’ve got just the resource you need. We’ve put together a list of 50 must-have apps that you should seriously consider before the world ends. Okay, so assuming the world continues on beyond December 21, these are the apps we feel are definitely worth your time and/or money.
Note that this is not necessarily our official endorsement of “the top 50 Android apps of all time” and that such a list is often hard to put together. That said, we really like this mix of apps and games as they speak well for Android. We’ll certainly put together more lists along these lines, especially as time goes and new stuff shows up.
Honestly, this is one of the more difficult things to assemble and we feel terrible having left of gems. You’ll notice that there are no big first-person shooters or high-res 3D games on the list. We tried to cater to the average user and come up with 50 titles we’d feel good telling anyone and everyone to check out. You could do much worse than to use this as a starting point for your foray into Android.
