I tend to set tasks with good intentions — write an essay, finish a book, feed the kids. And yet, I often find myself getting distracted by friends sending me a constant stream of cat GIFs. Now, you can resist the temptation using Forest — an app designed to help you stay focused on the job at hand. Choose the length of time you wish to abstain from your device. You’ll then see a tree begin growing on your device. Exit the app and the tree will wither before eventually dying a horrible, natural death (you cruel, cruel human being). The app provides useful statistics showing just how self-disciplined you truly are.
