The Christmas classic Love Actually closes on the Beach Boys tune ‘God only knows where I’d be without you.’ That’s the song I would dedicate to  the Freedom app.
Freedom is an app. that blocks your computer’s access to the internet. You set a timer, how many minutes or hours of ‘freedom’ you want, and you’re off the grid. Freedom can’t be switched off or overridden in any way before the timer runs out. In the words of Neil Gaiman, it ‘makes your computer something that’s never heard of the internet.’
