Twitter is launching its new Moments app in the UK today (15 December), showcasing how it can streamline the experience of using the social networking site. Available on Apple's app store and Google Play, the service aims to curate the best pictures, tweets, headlines and stories gathered from across Twitter for viewing in one handy at-a-glance feature. The service can be used to catch-up on the latest memes to rock the microblogging service or for keeping up to speed with favourite sport and news stories.
