Charm is a Twitter companion app for iOS to organise Tweets into collections, save articles for later, cue up playlists of music you find, or transcribe conversations. You can use it to tell stories, hold on to jokes, capture Tweetstorms and monologues. Charm has features to curate Tweets from events you’re watching, too. Twitter is a non-stop glimpse into what’s happening in the world, and Charm is a tool that helps make sense of it, for yourself or to share with others.
