If your response is, "Huh? Wha...? Yo???", then good for you!
I'll admit that I was tempted to download it for my phone, mostly just to play around and see what all of the fuss is about. But I stood strong and so far, I'm not yet Yo-able.
But the furor over Yo (which, yes, was hacked today...) made me reflect on what apps on my phone could be called a "time dump". Maybe you have them too -- those simple little "I'll just spend a minute" tools that can suck up half an hour in no time.
Leaving Facebook and Twitter out of the occasion, right now the app that I should probably kick to the curb is 2048. I'm not a huge gamer and I don't socially share my results (because they are so bad it's embarassing), but I'll admit to being slightly addicted to this one. To limit its productivity sucking capacity, I've decided that I'm only allowed to play it after my work day is done and my workout has been logged. After that, all bets are off!
Your turn: Do you have any apps that are currently killing your productivity?
