Here Are 13 Apps We Couldn't Live Without In 2013

It’s been an important year for apps, those chicklet-sized, colorful squares on your smartphone, not just because the companies behind them continued to command multi-billion dollar valuations, but because of their increasing impact on offline life. A few years ago, the apps we couldn’t live without were casually addictive games that created a small black hole in our daily commute. Now apps are playing the role of match-maker (Tinder), or helping us lose weight and keep it off (MyFitnessPal) or acting the part of digital concierge when it’s late and we really need a cab (Uber). As we rely on apps more and more, the Big Data plumbing behind them is helping marketers and advertisers get a better idea, for better or worse, of who we are.
