Perfect replacement for your default camera. I'm on a ROM with a pretty poorly working camera right now and Snap took care of that right away. Looks great, light on resources and overall higher quality than stock.
It seems like there's a shortage of good games in the Play Store right now, so I'm glad I came across this classic. It's somewhat similar to the original Pitfall but also adopts a bit of a Temple Run feel. Graphics are about PS1/Dreamcast quality.
Snack Pack is essentially a lightweight toolbox for customization. It comes with quite a few wallpapers, clean looking icons and links to all the top launchers in the play store - $1.50 seems a little steep, but the icons alone are worth it I'd say.
The problem with icon packs usually lies in the lack of replacement icons for your favorite apps - it doesn't matter how perfect the icons are if you still have 20 apps with the stock logo. Suave HD is beautiful and has 750+ icons.
Best set of premium widgets period. I used HD Widgets for a while for the Sense-style clock, but between the two BW definitely places first - you're not going to find a more customizable set of widgets anywhere else.
My absolute favorite Twitter app on any platform. Super customizable and adds a ton of functionality to Twitter like read later and comments with RTs. Brought to you by the same folks who brought you Friendcaster for Facebook.
I've been using GO Launcher for quite a while now, but the default Sense lock screen on my phone was still a little bland. With GO Locker, you can change your lock screen to anything - highly recommend to un-rooted users who want more customization.
You've probably seen tons of MMOs for Android like Star Legends or Order & Chaos - both of which are pretty entertaining, but kind of limited in the way of gameplay/story lines. Arcane Legends is the fullest MMO experience I've seen on Android so far
Privacy on the Web is a rising concern -- for Mac/Linux/PC, there's Tor. But what about Android?
From the developers who brought you Tor, there's now Orbot for Android - so you can rest assured that you'll remain anonymous, even on the go.
Probably one of the best Android first-person shooters out there (aside from NOVA 3, of course) - if you like COD and other FPS games, then you'll be hooked on this. (Note that you need to have a decent specced device in order to run MC 3)
You could get an iPad and drool over a stupid piano app, or you can stick with Android and get lost in this crazy synthesizer. Caustic 2 is a little different than most synth apps in the sense that it's more along the lines of a full-on DAW.
Pandora and iHeartRadio are great most of the time, but what about when you want to access local stations from around the world, or record what you're listening to. That's where Tunein comes into play.
