Ever wondered what you were doing on this day last year? Or the year before? Or the one before that? Then you need Timehop.

This memory-jogging app delves into your social media accounts (Facebook, Twitter, Instagram, Foursquare and Flickr) and your images to show you what you were doing on today's date throughout the past.

Information is presented in a pleasant way, by an amusing cartoon dinosaur. We're not quite sure if the app is trying to suggest you're a dinosaur, or not!
