Best Android apps for 2013 (unofficial The Verge awards!)

Inspired by a thread at /r/Android, I was wondering: what apps that were released in 2013 would you consider to be the best (both aesthetically and functionally)? The general sentiment on Reddit seems to be favoring Pushbullet. Let's have your three nominations (in no particular order) and have our own unofficial awards based on those votes. Apps that were not released in 2013 will be disqualified.
