These apps/games are good
Jetpack Joyride
Robot Unicorn Attack 2
Taptitude
Super Hexagon
Plants Vs. Zombies
Beat Hazard
Temple Run games
Steam
Amazon App Store (nice free apps somtimes :)
App Gratis (same as above)

Mikandi, a porn app. jk it's not must have:p Must haves are Battle.Net Mobile Authenticator, WhatsApp, TaskSwitcher (how this isn't there to begin with is beyond me), and an app that shows in numbers how much battery is remaining. Also ColorNote is good to have. And some program so I can block numbers. I also like to clean cache and stuff.

The best games are probably Robinson (dev, fix the damn latest crash bug please), Bubble Shoot and Bubble Totem. Marble Saga is good, so were Brightwood Adventures and Ice Age Village until I got bored. Shipwrecked and Dream Zoo were good until I was no longer able to play them in my phone because of the 35mb apk download limit. Dark Summoner is all right even though it's repetitive and not really fun.

Whatsapp is most used ofc:)
