Coffee shops (especially with endless coffee) is where I produce. I love the background noise and activity around me, it actually helps me be more productive and creative. In fact I got much of my studying done for my ordination exams in a coffee shop. So needless to say, coffee shops are where I go to get stuff done.
Yet, needless to say, I can't always work in a coffee shop, that is why I love this app called Coffitivity
It creates that nice, coffee shop "white noise" - just enough to make you feel like you are actually there.
They have apps available for the Mac, iOS and Android...so there is something there for everyone.
Check Coffitivity out and give yourself a boost of productivity (and if you don't believe that this can help...see the research HERE)
