The coolest part about the Words with Friends app? .... You can basically play Scrabble at your own pace! You don't have to get all anxious about putting down your tiles quick enough so that the next person can take their turn, making it your choice to stay up until 4AM playing.
4. Tiny Tower -- James randomly downloaded this app on my phone one day after seeing how awesome it was it was on Attack of the Show. I love to micro-manage things, and I love this game.

The coolest part about the Tiny Tower app? .... It works on real-time and progressively gets more difficult. Right now it takes me 1 1/2 days to build a floor. I like to race the clock to try and build the next floor before the previous one is completed. oh.my.gosh.so.much.fun.
