but a friend and former classmate of mine recommended using pomodoro, an old-school forced-focus technique that has something to do with a tomato (that's what pomodora means, in italian) and a genius named francesco cirillo. naturally, there's an iphone/ipod touch app for it. (to reassure the millenial in you; because, of course, nothing is legit if it doesn't have an app)
i've been using pomodoro over the past couple of days, and i've gotta say it works. go here to learn more about it.
