In 2011, the MTA began to look at ways of displaying service disruptions due to weekend engineering works in a visual format. On September 16, 2011, the MTA introduced a Vignelli-style interactive subway map, "The Weekender", to its website. The web app provided a way for riders to get information about any planned work, from late Friday night to early Monday morning, that is going on either on a service(s) or station(s) of the subway during the weekends. On June 11, 2012, the MTA duplicated "The Weekender" site as a free mobile app download for iOS. On November 29, 2012, an Android version of the app was released.
